Scope — This assessment examines the public institutional architecture governing U.S. counter-terrorism and counter-designated-terrorist strike activity, with particular emphasis on AFRICOM operations in Africa and Operation Southern Spear in the Western Hemisphere from 2025 through 12 September 2026, while using earlier statutory and policy instruments only where necessary to establish the governing baseline.

Executive Summary / BLUF

The verified public record does not support the proposition that the United States has ceased assessing civilian harm or abandoned formal accountability mechanisms for counter-terrorism strikes; instead, it supports a narrower but strategically more consequential conclusion, namely that Washington retains a substantial civilian-harm assessment architecture while providing insufficient public evidence to permit independent evaluation of whether several rapidly expanding strike campaigns are achieving their stated operational and strategic objectives.

Congress requires the Secretary of Defense to report annually, by 1 May, on civilian casualties resulting from U.S. military operations, requires consideration of credible public and nongovernmental reporting, and requires the unclassified report to be released publicly at the same time as its submission to Congress unless a written national-security certification justifies withholding it; Congress extended this reporting requirement through 31 December 2030.

The Department’s 2025 Section 1057 report assessed that U.S. operations during that calendar year caused 153 civilian deaths and 243 civilian injuries, all of the 2025 casualties identified in the report arising from three operations in Yemen, while SOUTHCOM assessed that no incident in its area of responsibility in 2025 met the Department’s “more likely than not” threshold for civilian casualties.

The same report demonstrates that the assessment machinery remains capable of revisiting old cases, because AFRICOM re-examined an April 2018 Somalia strike after receiving additional information and concluded that the operation had killed one additional civilian, a teenage male, beyond two previously acknowledged civilian deaths.

AFRICOM’s public reporting likewise has not disappeared: its official civilian-harm portal currently lists quarterly assessments through FY2026 Q2, covering the quarter ending 31 March 2026, when the command reported two newly received reports of possible civilian harm and three carried-over open assessments, with none closed during that quarter; however, the public portal does not presently list an FY2026 Q3 report covering April–June 2026, notwithstanding the existence of pending cases at the end of Q2.

The larger assessment deficit concerns campaign effectiveness and target-level transparency rather than the complete absence of civilian-harm procedures, because the Lead Inspector General reported that SOUTHCOM would not publicly disclose its measures of effectiveness for Operation Southern Spear, even as the command acknowledged that drug-trafficking organizations were adapting through alternative shipping routes, air traffic and containerized transport.

That distinction matters because Operation Southern Spear had already involved at least 45 small-vessel strikes and 156 people killed or presumed dead between September 2025 and March 2026, while cumulative obligations reached $647.0 million through 31 March 2026; the public record therefore permits measurement of operational activity and expenditure far more readily than measurement of strategic effect.

The principal governance risk is accordingly not “unaccounted warfare” in the absolute sense, but the development of an asymmetric accountability system in which strike occurrence, expenditure and selected civilian-harm determinations are visible while target-validation standards, campaign-level effectiveness metrics and the relationship between tactical outputs and strategic outcomes remain substantially outside the public record.

U.S. Counter-Terrorism Strikes: When Tactical Action Outruns Strategic Accountability

The contradiction in U.S. counter-terrorism policy is no longer the scale of force but the weakness of the public machinery used to judge whether that force works. Section 1057 of the National Defense Authorization Act for Fiscal Year 2018 requires an annual accounting of civilian casualties from U.S. military operations, yet the report covering 2025 reached Congress only on 10 August 2026, three months after the statutory deadline, while U.S. Southern Command had already obligated $647 million between September 2025 and March 2026 for Operation Southern Spear. The institutional question is therefore narrower and harder than whether Washington should reveal sensitive targeting intelligence: it is whether a government that conditions comparatively small counter-terrorism assistance programmes on baselines, indicators and independent evaluation can continue expanding lethal campaigns while disclosing progressively less evidence about whom they kill, what effects they produce and whether adversaries are adapting faster than the operations designed to suppress them.

The reporting obligation survived; the reporting discipline did not

Congress created a military-specific accountability requirement in the National Defense Authorization Act for Fiscal Year 2018, requiring the Secretary of Defense to provide the congressional defence committees with an annual accounting of civilian casualties caused by U.S. military operations no later than 1 May, which makes delayed reporting a statutory performance issue rather than a dispute over voluntary transparency. The chronology recorded in the dossier is difficult to dismiss as a single administrative failure: the report covering 2023 arrived in December 2024, the report covering 2024 arrived in July 2025, and the report covering 2025 arrived on 10 August 2026, even though that latest document states that its casualty determinations were current as of 1 February 2026, three months before the legal deadline and six months before delivery to Congress. National Defense Authorization Act for Fiscal Year 2018

The content of those reports makes the delay more consequential because the assessed civilian toll rose from two people killed and two injured in the 2024 report to 153 killed and 243 injured in the 2025 edition, all in Yemen, while the statutory framework also requires the unclassified report to be made public when transmitted to Congress unless the Secretary certifies that publication would threaten national security. The institutional problem is therefore not that the Pentagon lacks a reporting mechanism, but that a mechanism specifically created to connect military action with congressional oversight has repeatedly failed to operate on the timetable Congress prescribed. 2024 Civilian Casualty Report

AFRICOM moved from casualty counts to geographic coordinates

The deterioration is visible at the level of operational disclosure as well as statutory reporting, because U.S. Africa Command stated in January 2024 that a strike near Caad in central Somalia killed six al-Shabaab members and no civilians, while by March 2025 its public language had contracted to the statement that enemy combatants had been killed and no civilians injured or killed, and by August 2026 releases were routinely limited to the date, targeted organization and distance from the nearest town. The operational-security explanation is incomplete on the dossier’s own evidence because releases across all three periods carried effectively the same warning that units and assets would not be disclosed, meaning that the security restriction remained constant while the information provided about results materially declined. U.S. Africa Command, January 2024 strike release

AFRICOM’s separate civilian-harm publication series had once offered a second layer of accountability, beginning in April 2020 and running for 22 consecutive editions, but the dossier records that the most recent assessment then available covered the period ending 30 June 2025, leaving four quarters from July 2025 through June 2026 unpublished during what the dossier describes as the command’s largest sustained strike campaign. Members of Congress had welcomed the quarterly mechanism when it was established, precisely because it supplied information that individual strike releases could not, yet the disappearance of that cumulative assessment layer means that the public is increasingly asked to infer campaign performance from announcements that disclose progressively less. AFRICOM Civilian Harm Reporting

Southern Spear makes the financial asymmetry impossible to ignore

The accountability problem becomes harder to treat as a communications issue when expenditure is considered, because U.S. Southern Command reported obligating $527.9 million in a single quarter for Operation Southern Spear and $647 million between September 2025 and March 2026, while the first Lead Inspector General report delivered to Congress in May 2026 recorded that the operation’s mission statement was classified, the list of organizations designated for targeting was not publicly releasable, the accounting of strikes was withheld, the criteria used to choose between lethal action and non-lethal interdiction were not disclosed, and SOUTHCOM would not publicly release its measures of effectiveness. Operation Southern Spear, Lead Inspector General Report

That imbalance matters because expenditure can be audited without revealing targeting intelligence, while effectiveness can be evaluated in aggregate without publishing sources, methods or patterns of life; nevertheless, when the Inspector General sought even a strike count, the dossier records that it had to construct one from the New York Times and ABC News because the command would not provide a public figure. The result is an accountability structure in which Congress and taxpayers can see hundreds of millions of dollars being obligated but cannot reconstruct from the public record the basic chain from expenditure to strike activity, from strike activity to disrupted trafficking, and from disruption to the policy objective the operation was intended to achieve. Operation Southern Spear, Lead Inspector General Report

A zero-civilian-casualty finding raises a classification question, not a numerical one

The 2025 civilian-casualty report records no civilian casualties from the maritime campaign in the Caribbean and eastern Pacific, while the dossier records that the campaign had killed at least 221 people in no fewer than 66 strikes and that Representative Sara Jacobs, a member of the House Armed Services Committee, said after a briefing that defence officials did not require positive identification of every person aboard targeted vessels, provided that a connection to one of the organizations designated as foreign terrorist organizations in 2025, or an affiliate, could be established. That combination does not by itself prove that the Department’s civilian-casualty assessment is wrong, but it makes the underlying classification methodology central to any serious evaluation of the reported zero. 2025 Civilian Casualty Report

The dossier identifies the problem concretely through the 2 September strike in which 11 people aboard a vessel came from communities on Venezuela’s Paria peninsula, an area described in local reporting as a hub for human trafficking, while Rear Adm. Brian Bennett of the Joint Staff acknowledged in a classified briefing that some of the dead could have been trafficking victims. If a person aboard a designated vessel can potentially be a trafficking victim rather than a member of the designated organization, the analytical question becomes whether civilian status is being assessed individually after the strike or inferred from the pre-strike classification of the vessel and its presumed organizational connection; the public record described in the dossier does not resolve that distinction. Joint Staff briefing account

Tactical pressure is visible; strategic effect is not

The strongest evidence that strike counts are an inadequate measure of performance comes from SOUTHCOM itself, because the May 2026 Lead Inspector General report records the commander’s testimony that cartels had adapted to military pressure by changing routes and shifting activity toward air traffic and shipping containers. That adaptation can represent successful deterrence if the new routes are materially more expensive, slower or less reliable, but it can represent simple displacement if cocaine reaches the United States in similar quantities through alternative channels; the dossier records only one direct assessment of the market effect, a leaked Drug Enforcement Administration analysis finding no change in cocaine supply or price. Operation Southern Spear, Lead Inspector General Report

The contrast with State Department counter-terrorism assistance is unusually sharp because the dossier records that roughly 20 East African projects worth about $80 million annually between 2018 and 2025 operated with baselines, agreed indicators, continuing performance reporting and independent evaluation, while underperforming programmes or programmes that failed to report could have funding withheld. A 2020 State Department Office of Inspector General inspection nevertheless found that the Bureau of Counterterrorism itself was not meeting departmental monitoring standards and identified one employee responsible for 86 projects worth almost $147 million, after which the failure was formally documented and corrective action required; the relevant difference is therefore not that civilian assistance performed perfectly, but that underperformance itself entered an institutional evaluation process. State Department Office of Inspector General, 2020 inspection

The cost of secrecy is highest when partners disclose what Washington withholds

The operational-security case for restraint is legitimate because detailed battle-damage assessments can expose sources, methods and patterns of life, while al-Shabaab and the Islamic State can exploit erroneous public claims for propaganda purposes; however, the dossier records that AFRICOM releases in 2024 and 2025 had already published casualty numbers and named individuals while withholding units and assets, and that the quarterly civilian-harm series ran for 22 editions without any cited adverse operational-security incident. The relevant policy choice is therefore not between full tactical disclosure and silence, but between releasing aggregate information sufficient to judge results and withholding even the outputs that would permit outsiders to test whether the campaign is producing durable effects.

The contradiction became particularly visible after the joint U.S.-Nigerian operation of 16 May 2026, when AFRICOM reported only that American and Nigerian forces had killed multiple terrorists and stated on 18 May that analysts were completing their assessments, while the dossier records that the command never subsequently published the result; on 19 May, by contrast, Nigeria’s Defence Headquarters announced that its own assessment indicated that the operation had eliminated 175 Islamic State fighters, named three additional commanders and listed destroyed targets, although the dossier explicitly notes that this figure was not independently verified. Washington and Abuja faced the same adversary and propaganda environment, yet the partner government supplied the only numerical public account of an operation involving U.S. forces. AFRICOM, 16 May 2026

Over the next 12–24 months, Congress will either restore the measurement chain or finance a widening information deficit

The next 12–24 months will determine whether the present reporting gap becomes an administrative episode or an institutional model, because Section 1057 already supplies Congress with a statutory casualty-reporting mechanism, 22 U.S.C. §2656f separately requires the Secretary of State to transmit an annual terrorism report by 30 April, and the dossier records that the edition released on 1 May 2026 still covered 2024 rather than 2025. The pattern therefore extends beyond one combatant command: statutory reporting is arriving late or with outdated reporting periods while military activity and expenditure continue in real time. Country Reports on Terrorism 2024 — U.S. Department of State

The cost of inaction will fall first on Congress, because appropriators will be asked to authorize or continue funding without a stable public chain connecting inputs, operations and outcomes; it will fall on the Department of Defense, because progressively thinner reporting transfers credibility from documented evidence to institutional assertion; and it will fall on taxpayers, because $647 million committed to Southern Spear by March 2026 becomes impossible to evaluate against strategic effect if the command’s measures of effectiveness remain unavailable even in sanitized form. Congress does not need tactical intelligence to correct that imbalance, because it can condition future appropriations on the reporting requirements already established and insist that classified operational detail remain protected while aggregate outcomes, casualty assessments and effectiveness measures return to an auditable schedule.

Legal and institutional accountability architecture

The controlling issue is whether existing law and Department policy require enough information to establish what happened, whom operations harmed, how those determinations are reached and whether reporting mechanisms are functioning consistently across combatant commands.

Operational transparency and measurable effectiveness

The central analytical problem is the widening separation between measurable tactical activity — strikes, vessels attacked, forces deployed and money obligated — and the limited public evidence establishing whether those activities are producing the intended strategic outcomes.

Governance consequences and decision thresholds

The principal decision question for Congress and the executive branch is not whether sensitive operational information must become public, but whether classified effectiveness measures can remain unavailable even in aggregated or sanitized form without weakening appropriations oversight, policy evaluation and institutional accountability.

Master Abstract

The public record shows an assessment architecture, but not a complete assessment chain

The strongest conclusion permitted by the official record is that the United States retains a considerably more developed civilian-harm assessment framework than a simple “transparency collapse” thesis would imply, yet that framework does not answer the separate question of whether current counter-terrorism and counter-designated-terrorist strike campaigns are strategically effective. Congress’s Section 1057 requirement obliges the Secretary of Defense to submit an annual report by 1 May on civilian casualties resulting from U.S. military operations during the preceding year, to consider credible all-source information including public and nongovernmental reporting, and to make the unclassified report publicly available when it is submitted to Congress unless publication is withheld through a written national-security determination; the FY2025 NDAA subsequently extended that statutory reporting architecture through the end of 2030.

Department policy goes further at the combatant-command level, because DoDI 3000.17, Civilian Harm Mitigation and Response, directs combatant commands to publish information at least quarterly concerning the status and results of civilian-harm reviews, assessments and investigations, subject to specifically enumerated exceptions involving operational security, investigative integrity, privacy, sensitive information and malicious disinformation. The same instruction requires reports, when publicly releasable, to identify newly reported incidents, pending cases, completed assessments and assessed civilian deaths or injuries, while permitting a command to omit a quarterly publication only if no new relevant incidents were received, no relevant assessment remained pending and no assessment was completed during the quarter.

That policy baseline makes the present accountability problem more precise rather than less serious, because the central deficiency lies increasingly in campaign evaluation rather than purely casualty reporting. The public record documents strikes, expenditure and selected casualty assessments, yet it provides substantially less visibility into the causal chain connecting those inputs to the missions’ declared strategic purposes.

Civilian-harm accounting remains institutionalized and capable of revision

The Department’s Annual Report on Civilian Casualties in Connection with United States Military Operations in 2025 provides the clearest current evidence that the assessment mechanism remains operational, because the Department concluded that military operations during 2025 caused 153 civilian deaths and 243 civilian injuries, applying a “more likely than not” evidentiary standard and explaining that the assessment process incorporates operational data, intelligence, imagery, open-source reporting and, where available, external information.

Those casualties were attributed to three operations in Yemen: the Department assessed 5 killed and 25 injured in Sanaa on 6 April 2025, 80 killed and 171 injured at Ras Isa Port on 17 April, and 68 killed and 47 injured near Saada on 28 April, producing the reported annual total of 153 killed and 243 injured. The report simultaneously recorded 15 additional Yemen incidents still undergoing assessment as of 1 February 2026, demonstrating that the annual figure represented a completed-assessment position rather than an assertion that all possible civilian-harm cases had been resolved.

The same document is analytically important for another reason, because AFRICOM’s reassessment of an April 2018 strike near El Burr, Somalia, using previous assessment material, strike footage evaluated with new methods, additional interviews and information supplied by civil-society organizations, resulted in acknowledgement of a third civilian death from an incident for which two civilian deaths had previously been recognized. That outcome establishes that the Department’s process can be evidentially reversible when sufficiently material new information becomes available, an institutional feature that strengthens the credibility of the architecture even though it does not establish the completeness of any individual assessment.

The appropriate analytical conclusion is therefore that official casualty figures represent Departmental assessments under a defined evidentiary methodology, rather than an independently exhaustive census of all civilians potentially harmed by U.S. operations.

AFRICOM combines very high strike tempo with thinner immediate strike-level disclosure

AFRICOM’s official strike register recorded 78 strikes during 2026 through 7 August, after which official releases confirm additional al-Shabaab strikes conducted on 4, 5 and 8 September 2026, establishing at least 81 publicly acknowledged AFRICOM strikes during the year through the latest of those operations.

The most recent individual strike releases identify the partner government, target organization, strike date and approximate geographic location while withholding details regarding units and assets on operational-security grounds; for example, AFRICOM’s release concerning the 7 August strike near Jilib states that the operation targeted al-Shabaab approximately 322 kilometres southwest of Mogadishu, while the 4 September operation is described as occurring approximately 175 kilometres west of Mogadishu, with neither release providing a casualty estimate or target-identification detail.

This reduced strike-level detail does not, by itself, establish non-compliance with civilian-harm policy, because DoDI 3000.17 expressly permits withholding or limiting information where publication could compromise classified or sensitive information, reveal operational patterns, obstruct investigations or amplify malicious disinformation. It nevertheless means that the public cannot infer battle-damage assessment, target-validation quality or civilian-harm status from the press releases themselves, which places greater institutional importance on the quarterly civilian-harm reporting system.

AFRICOM’s current public civilian-harm portal lists reports through FY2026 Q2, ending 31 March 2026, and that report records two new civilian-harm reports together with three carried-over open assessments, leaving five unresolved cases at quarter-end. Because the command’s portal presently does not list a Q3 FY2026 report covering April through June, the public record as of 12 September does not establish the subsequent status of those five cases through the quarterly reporting mechanism, although the absence of a presently listed report is not by itself sufficient to determine whether an authorized withholding or publication delay has occurred.

Operation Southern Spear exposes the sharper effectiveness-accountability problem

The most consequential evidence of an assessment gap appears in the Lead Inspector General’s reporting on Operation Southern Spear, because the operation combines substantial kinetic activity, significant public expenditure and an expressly stated strategic purpose with publicly unavailable effectiveness metrics. The first Lead IG report states that the operation was initiated in November 2025 to disrupt narcotics flows from designated terrorist organizations and transnational criminal organizations in the Western Hemisphere, while noting that the formal mission statement itself remains classified.

Between September 2025 and the end of March 2026, the U.S. military had struck at least 45 small boats, producing 156 individuals killed or presumed dead, while SOUTHCOM reported approximately $527.9 million in obligations during January–March 2026 alone and $647.0 million cumulatively from September 2025 through 31 March 2026. The quarterly expenditure included $248.8 million for operations, $58.3 million for personnel and $220.8 million for transportation across the Air Force, Navy, Marine Corps, Army and U.S. Transportation Command.

Those figures establish the scale of effort but not its effectiveness, because the same Lead IG report states that SOUTHCOM would not publicly release the measures of effectiveness it uses to assess Operation Southern Spear. General Francis Donovan nevertheless told Congress that trafficking organizations had adapted to military pressure by shifting routes farther west into the Pacific and relying more heavily on air transport and shipping containers rather than small boats, while a senior Department official argued that lethal strikes were intended to generate deterrence by raising the perceived cost of maritime narcotics movement.

The official record therefore supports competing mechanisms rather than a settled effectiveness judgment: kinetic strikes can increase risk and disrupt a specific maritime trafficking modality, yet traffickers can respond by route substitution, modal substitution, logistical dispersion or concealment inside commercial flows, which means a reduction in one observable transport channel does not necessarily equal a reduction in overall narcotics supply. Because the command’s aggregate effectiveness metrics are not public, the official record does not presently permit determination of which mechanism dominates.

Classification creates a legitimate boundary, but not a complete policy answer

Operational secrecy has a valid institutional basis, because the Department’s civilian-harm instruction expressly recognizes that aggregated disclosures can reveal tactics, operational patterns, sources, vulnerabilities and sensitive capabilities, while the Lead IG record confirms that portions of the Southern Spear mission architecture, targeted-organization list, personnel deployment and basing information remain non-public.

The policy problem arises when the protection of those inputs also removes the outputs required to judge public policy, because it is possible to protect target intelligence, surveillance methods, platform characteristics and rules of engagement while still releasing sanitized aggregate measures such as interdicted or displaced trafficking volume, route substitution, estimated network attrition, reconstitution rates, operational cost per measurable effect and changes in drug-flow indicators. The present record does not establish that such disclosure is impossible; it establishes only that SOUTHCOM has declined to release its effectiveness measures publicly.

This distinction is important for congressional governance because appropriations oversight cannot be reduced to knowing how much was obligated, while operational oversight cannot be reduced to knowing how many platforms were struck and accountability cannot be reduced to determining whether civilians were harmed. An analytically complete assessment chain requires at least four separable questions — Was the target valid; was the strike executed as intended; what harm resulted; and did the cumulative campaign advance its stated strategic purpose — whereas the current public record provides materially different levels of visibility across those four questions.

Competing Explanations or Pathways

The ACH gate is met because the same observed reduction in public operational detail can plausibly arise from materially different institutional mechanisms whose implications diverge and whose future indicators are observable.

Hypothesis	Diagnostic support	Disconfirming evidence	Indicators	Current standing
Operational-security recalibration	DoDI 3000.17 expressly authorizes withholding where disclosure threatens classified information, reveals operational patterns or affects investigations, while several Southern Spear mission elements are formally non-public.	Aggregate effectiveness measures do not inherently require disclosure of platforms, sources or target intelligence, and the official record does not establish that every meaningful aggregate indicator is operationally sensitive.	Resumption of sanitized aggregate outcome reporting while tactical details remain classified would strengthen this explanation.	Materially supported, but insufficient by itself to explain the breadth of the assessment gap.
Institutional shift toward output-based reporting	Official releases readily report strike occurrence, location, targets and expenditure, while strategic effectiveness measures remain substantially less visible.	Civilian-harm reassessment mechanisms remain active, including AFRICOM’s reopening of historic cases, showing that the Department has not wholly retreated from outcome assessment.	Continued growth in strike counts and expenditure reporting without equivalent outcome metrics would strengthen this pathway.	Strongly supported in the current public record.
Temporary reporting lag during operational expansion	AFRICOM retains a quarterly reporting architecture, and its latest public report still identifies unresolved cases rather than declaring them closed without explanation.	The absence of presently accessible Q3 FY2026 civilian-harm reporting while five cases remained open at Q2’s end weakens the proposition if the gap persists without a stated policy exception.	Publication of Q3/Q4 assessments with continuity of case identifiers and dispositions would substantially strengthen this explanation.	Plausible but presently unresolved.
Structural transparency contraction	SOUTHCOM withholds campaign effectiveness measures, strike-level casualty information is limited, and substantial parts of the mission architecture remain non-public.	Section 1057 reporting, DoDI 3000.17, AFRICOM’s quarterly mechanism and retrospective reassessment remain operative, which contradicts the stronger proposition that accountability architecture has been dismantled.	Failure to publish pending quarterly assessments, declining detail in statutory reports, or new exemptions from civilian-harm reporting would strengthen this hypothesis materially.	Partially supported, but the evidence currently supports selective contraction rather than systemic abolition.

Principal Gaps and Watch Indicators

The most important unresolved record concerns Southern Spear’s actual measures of effectiveness, because disclosure of even sanitized indicators covering drug-flow disruption, route displacement, network regeneration, interdiction substitution and marginal cost per operational effect would materially change the ability to determine whether the campaign is producing strategic effect rather than merely tactical attrition.

A second decisive gap concerns AFRICOM’s FY2026 Q3 civilian-harm reporting, because five assessments remained open at the end of March 2026 and the current public portal does not list the quarter covering April through June; publication of that report, or an official explanation invoking a specific DoDI 3000.17 exception, would materially clarify whether the current discontinuity reflects routine lag, authorized withholding or a weakening of reporting practice.

A third gap concerns target-status assessment in Southern Spear, because the Section 1057 report states that SOUTHCOM assessed no civilian-casualty incident from its 2025 operations, but the public document does not provide a vessel-by-vessel account explaining the status assigned to every person killed, while DoDI 3000.17 defines the civilian-harm assessment framework separately from the broader strategic question of whether a person was properly targetable under the legal and operational authority being exercised.

A fourth indicator is whether Congress seeks classified-to-unclassified bridging mechanisms, such as mandated aggregate outcome reporting, statutory certification that campaign-level metrics have been reviewed, or Inspector General publication of sanitized measures that preserve tactical secrecy while permitting oversight of strategic effectiveness.

A fifth indicator is the evolution of route and modality substitution, because SOUTHCOM’s own commander has already reported movement toward air traffic, shipping containers and more westerly Pacific routes, meaning that tactical success against small boats would become strategically ambiguous if trafficking volumes simply migrate into less vulnerable channels.

Net Assessment

The public record establishes a meaningful but precisely bounded accountability gap: the United States continues to possess statutory civilian-casualty reporting, command-level civilian-harm assessment, retrospective case review and Inspector General oversight, yet these mechanisms do not presently provide a complete public basis for judging whether some of the most kinetic contemporary counter-terrorism and counter-designated-terrorist campaigns are producing their claimed strategic outcomes.

The distinction between civilian-harm accountability and campaign-effectiveness accountability is decisive, because a strike can be accurately assessed as having caused no civilian casualties while still being strategically ineffective, just as a campaign can impose substantial tactical costs on an adversary while generating displacement rather than durable suppression. Operation Southern Spear makes that analytical problem unusually visible because official sources simultaneously document a substantial number of strikes, at least 156 killed or presumed dead through March 2026, and $647 million in cumulative obligations, while the command’s formal measures of effectiveness remain outside the public record and its commander acknowledges adversary adaptation.

AFRICOM presents a somewhat different governance profile, because the command has preserved a structured civilian-harm assessment system and publicly maintains an extensive strike register, yet the latest publicly listed quarterly civilian-harm assessment covers only the period ending 31 March 2026, notwithstanding continued high operational tempo and unresolved cases. The appropriate institutional judgment is therefore neither that the system is transparent nor that it has ceased functioning, but that public accountability is increasingly fragmented across separate reporting instruments whose combined output remains insufficient to connect tactical activity, target assessment, civilian consequences, expenditure and strategic effect into a single auditable chain.

Legal and institutional accountability architecture

Principal judgment

The United States possesses a materially stronger legal and institutional framework for documenting civilian harm from military operations than the current level of public operational disclosure might suggest, because Congress has imposed recurring statutory reporting duties, the President has retained an executive policy framework governing pre- and post-strike civilian-protection measures, the Department has converted those principles into a standardized assessment system under DoDI 3000.17, and combatant commands are required to maintain dedicated civilian-harm structures, preserve records, reassess cases when new information emerges and publish qualifying information at least quarterly unless specified exceptions apply. The decisive weakness therefore lies less in the absence of formal rules than in the distance between what the system requires internally, what it requires to be transmitted to Congress, and what ultimately becomes available to the public in a form that allows cross-command scrutiny.

That distinction is essential because four separate accountability questions are often collapsed into one: whether the operation had a lawful authority; whether the target and attack complied with applicable law and operational rules; whether civilians were killed, injured or otherwise harmed; and whether the campaign itself achieved the strategic objective for which force was employed. Existing law and policy impose significant documentary requirements across the first three questions, but they do not create an equally comprehensive public reporting regime for the fourth, and this asymmetry becomes particularly important when kinetic activity expands faster than the public evidence demonstrating its strategic effect.

Congress created a statutory floor that executive policy cannot simply replace

The core civilian-casualty reporting requirement derives from Section 1057 of the National Defense Authorization Act for Fiscal Year 2018, as subsequently amended, which requires the Secretary of Defense to report annually to the congressional defense committees on civilian casualties caused by U.S. military operations during the preceding year, with the reporting architecture now extended through 31 December 2030. The current statutory regime is therefore neither a voluntary transparency practice nor merely an executive-branch convention; it is a congressionally mandated accountability mechanism whose continued operation no longer depends upon whether a particular administration wishes to preserve the earlier executive reporting model.

The importance of that statutoryization became particularly clear in 2019, when Executive Order 13862 revoked Section 3 of Executive Order 13732, which had required the Director of National Intelligence to publish an annual unclassified summary of U.S. counter-terrorism strikes outside areas of active hostilities together with estimated combatant and non-combatant deaths. The revocation did not eliminate the broader civilian-protection policy contained in Executive Order 13732, because the 2019 order removed only that specific reporting provision while leaving the remainder of the 2016 framework in force, and the White House explicitly justified the change in part on the existence of the congressional Section 1057 mechanism.

This history produces an important institutional consequence: the present system is deliberately bifurcated between statutory reporting to Congress and executive/Department policy governing operational assessment, rather than resting on a single presidential transparency instrument. Executive Order 13732 continues to state that civilian protection is compatible with effective use of force and directs relevant agencies to maintain practices intended to reduce civilian casualties, investigate relevant incidents and draw lessons from operations, while Section 1057 separately requires an annual accounting to Congress.

The statutory architecture also reaches beyond the annual casualty report, because 50 U.S.C. §1549 requires the President, by 1 March each year, to report to designated congressional committees on the legal and policy frameworks governing U.S. uses of military force and related national-security operations, including the legal and factual basis for changes in those frameworks, the groups against which force is deemed legally available under the 2001 Authorization for Use of Military Force, and the criteria for determining whether a foreign force, group or individual is lawfully targetable. The statute requires the unclassified portion to be released publicly when submitted to Congress, although classified annexes remain permissible.

A second complementary mechanism, 50 U.S.C. §1550, requires reporting every 180 days on uses of force pursuant to the 2001 AUMF and on specified circumstances in which U.S. forces command, coordinate, move with or accompany foreign forces engaged in hostilities, including the legal and factual basis for treating particular organizations as covered by the authorization, the countries in which operations occurred, the circumstances requiring force and the expected scope and duration of operations. These provisions do not substitute for the civilian-harm regime, but they establish that Congress has constructed an accountability framework intended to connect authority, geography, adversary and operational activity, rather than treating casualty accounting as an isolated administrative exercise.

The Department has deliberately separated legal compliance from civilian-harm assessment

The most important doctrinal distinction in the present architecture is that civilian harm and unlawful conduct are not synonymous, and Department policy is explicit on this point. DoDI 3000.17 states that its civilian-harm requirements support implementation of the law of war while also imposing supplementary policy measures that go beyond what the Department regards as legally required; it further states that the occurrence of civilian harm does not in itself demonstrate a law-of-war violation and that the instruction creates no privately enforceable substantive or procedural right.

This separation is analytically sound because lawful attacks can still produce civilian casualties under the law of armed conflict where the target is a lawful military objective, expected incidental civilian harm is not excessive in relation to the anticipated concrete and direct military advantage, and feasible precautions have been taken; conversely, the absence of assessed civilian casualties does not by itself establish that targeting, authority or execution complied with every applicable rule. The Department's own 2025 annual report identifies distinction, proportionality and feasible precautions as relevant law-of-war protections but treats civilian-harm assessment as a separate process intended to determine whether civilian casualties more likely than not resulted from U.S. operations.

Where information obtained during a civilian-harm assessment indicates a possible law-of-war violation, however, the system is designed to switch from the civilian-harm track into the formal law-of-war reporting architecture. DoDI 3000.17 requires the Civilian Harm Assessment Cell, or the unit conducting the assessment, to refer credible information indicating a potential law-of-war violation through the chain of command under DoDD 2311.01, while credible indications of criminal activity require suspension of the civilian-harm assessment, preservation of evidence and referral to the appropriate criminal investigative authority.

Under DoDD 2311.01, DoD Law of War Program, combatant commanders are required to report qualifying incidents through operational reporting channels to the Chairman of the Joint Chiefs of Staff, Secretary of Defense and other designated authorities, with information subsequently distributed to offices including the Department's General Counsel, policy leadership, intelligence leadership, legislative affairs and Inspector General. The architecture therefore creates a potentially significant institutional escalation path when an ordinary civilian-harm review produces credible information suggesting unlawful conduct rather than merely unintended harm.

The distinction also protects analytical integrity because it prevents casualty assessments from being treated as surrogate criminal judgments, while simultaneously preventing the civilian-harm process from becoming a procedural dead end when evidence of misconduct emerges.

DoDI 3000.17 created a standardized Department-wide assessment system

The December 2023 issuance of DoDI 3000.17, Civilian Harm Mitigation and Response, converted the reform programme begun under the 2022 Civilian Harm Mitigation and Response Action Plan into a binding Department-wide policy instrument assigning responsibilities across the Office of the Secretary of Defense, Joint Staff, combatant commands and military departments. The instruction requires civilian-harm assessments to be conducted regardless of the sensitivity or security classification of the operation, directs the collection and preservation of relevant operational data, and requires consideration of information from both U.S. Government and external sources.

At combatant-command level, the instruction requires the establishment or maintenance of Civilian Harm Assessment Cells, together with a Civilian Harm Assessment and Investigation Coordinator at command level or, where appropriate, within subordinate operational commands. These cells are expected to combine expertise in intelligence, joint fires, civil-military relations, post-strike analysis, regional and cultural knowledge and legal advice, while the Department's Civilian Protection Center of Excellence is charged with providing training, analytical support, doctrinal development and institutional learning across the force.

The procedural architecture begins when information indicates that civilian harm may have resulted from a U.S. military operation, at which point the command conducts an initial review intended to correlate the report with U.S. operational data and determine whether sufficient grounds exist for a fuller assessment or investigation. The individual or unit conducting the review is required to be objective and not directly involved in the event being assessed, while the documentation should identify relevant information sources, describe the information underlying the preliminary conclusion and recommend whether the matter should progress to a civilian-harm assessment or formal investigation.

When a full civilian-harm assessment proceeds, the assessing unit must likewise not have been directly involved in the event, must consider all reasonably available information from military, governmental and external sources, and must produce a report that, where practicable, records the assessment result, information sources, evidentiary basis, potential need for investigation, lessons learned and recommendations for reducing future civilian harm.

The applicable evidentiary threshold is the Department's “more likely than not” standard, meaning that civilian harm is assessed as resulting from U.S. military operations when the available information provides greater reason to believe that it occurred than that it did not. Where casualties are assessed to have occurred, the assessment should, to the extent practicable, distinguish deaths from injuries and provide a specific number or bounded estimate when exact determination is impossible.

This is a consequential institutional standard because it is higher than mere plausibility but does not require the degree of proof associated with a criminal proceeding, which makes it appropriate for operational fact-finding while simultaneously limiting what can legitimately be inferred from a negative assessment. A conclusion that civilian harm was not established under the “more likely than not” standard therefore means that available evidence did not cross the Department's assessment threshold; it does not logically establish that no civilian harm occurred.

External information is formally admissible rather than peripheral

The current policy expressly rejects a closed intelligence model in which only military-generated reporting is considered, because DoDI 3000.17 requires commands to consider reasonably available information from external sources and contemplates material from nongovernmental organizations, news reporting, social media, local authorities, witnesses, allies and partner governments alongside intelligence, surveillance and reconnaissance data and operational reporting.

The Department's 2025 annual report demonstrates that this is more than nominal language, because CENTCOM reported continuing assessments of 15 Yemen incidents arising from NGO reporting as of 1 February 2026, while AFRICOM reported that its 2025 civilian-harm workload included reports received through its public portal, civil-society organizations and open sources.

The strongest demonstration of evidentiary reversibility is AFRICOM's reassessment of the 1 April 2018 El Burr, Somalia strike, which had already resulted in acknowledgement of two civilian deaths; after receiving additional civil-society information, the command reopened the case, revisited original source material and strike footage using newer analytical methods, conducted additional interviews and ultimately acknowledged the death of an additional civilian, identified in the official report as a teenage male.

DoDI 3000.17 expressly institutionalizes this principle by requiring an assessment to be reopened, or an investigation initiated, when previously unassessed relevant information emerges that could alter an approved result or when other developments create significant doubt about the accuracy of the previous conclusion.

That reopening mechanism is one of the strongest elements of the current architecture because it recognizes that operational information is inherently incomplete at the time of a strike and that later access to witnesses, imagery, civil-society evidence or improved technical analysis can change the evidentiary balance.

Public reporting is mandatory in principle but contains substantial command discretion

DoDI 3000.17 does not merely require internal assessment; paragraph 5.3 directs combatant commands to publish information at least quarterly on their unclassified public websites concerning the status and results of civilian-harm reviews, assessments and investigations, subject to defined exceptions. The required public content includes newly identified incidents, pending cases, reopened cases and completed assessments, with completed cases ordinarily describing the date, location and type of operation, its general purpose, whether civilian casualties were assessed as more likely than not, and the assessed numbers killed and injured.

The rule nevertheless contains four important limitation mechanisms, because commanders can omit, delay or restrict information when public disclosure would compromise confidentiality, impede an assessment or investigation, interfere with legal proceedings or individual privacy, amplify adversarial disinformation, reveal classified or sensitive information, or expose operational patterns, tactics, techniques and procedures through data aggregation.

A command may dispense with a quarterly report entirely only where all three specified conditions are met during the relevant quarter: no new possible civilian-casualty incidents were identified or received; no reviews, assessments or investigations remained pending; and no relevant reviews, assessments or investigations were newly completed. This requirement is particularly important for cross-command audit because it means that complete silence cannot automatically be interpreted as an authorized “nothing to report” quarter when unresolved cases remain open.

At the same time, the exceptions mean that public reporting is not mechanically identical to internal assessment. A command can remain internally compliant with assessment and record-retention requirements while publicly disclosing substantially less information if it invokes one of the policy's operational, investigative or security limitations, and the instruction does not require that every withholding decision be accompanied by a detailed public legal explanation that would itself disclose the protected information.

The central accountability tension therefore resides not in whether exceptions exist — some are operationally unavoidable — but in whether their application remains narrow, auditable and comparable across commands.

AFRICOM currently provides the clearest command-level implementation record

AFRICOM's public portal presents the most visible example of the quarterly mechanism contemplated by DoDI 3000.17, because the command has published civilian-harm assessment reports since April 2020 and explicitly states that its current reporting practice is carried out in accordance with the Department-wide instruction. Its FY2026 second-quarter report, covering the period ending 31 March 2026, recorded two new civilian-harm reports, three reports carried forward from earlier quarters and no assessments closed, leaving five assessments open at quarter-end.

That publication illustrates several strengths of the institutional model because it distinguishes newly received cases from carried-over cases, reports unresolved workload rather than only confirmed casualty events, identifies the evidentiary threshold applied by the Department and states that previous assessments can be reopened when new relevant information emerges.

The same record also creates a measurable accountability test: because five cases remained open at the end of March, the “no report necessary” exception contained in paragraph 5.3(g) could not be satisfied for a subsequent quarter merely on the ground that no new incidents had been received, unless those cases had first been completed or otherwise removed from the pending category under an applicable withholding provision. The public AFRICOM portal currently lists reports through FY2026 Q2, so the absence of a publicly listed Q3 report covering April–June 2026 is analytically significant, although the official record reviewed here does not establish whether this reflects publication delay, a deliberate limitation under paragraph 5.3, or another administrative circumstance.

The correct institutional formulation is therefore that a reporting discontinuity is observable, while non-compliance is not yet established by the public record alone.

CENTCOM demonstrates that annual statutory reporting can contain more detail than routine operational releases

The 2025 Section 1057 report provides substantial detail concerning CENTCOM operations in Yemen, identifying three incidents assessed as more likely than not to have produced civilian casualties and reporting an aggregate 153 civilians killed and 243 injured, distributed across strikes in Sanaa on 6 April, Ras Isa Port on 17 April and the vicinity of Saada on 28 April 2025.

The report further describes the evidentiary basis at a generalized level, noting the use of U.S. intelligence, imagery and open-source reporting and explaining that witness interviews and site visits were not conducted in those specific cases because of the contested operational environment. This matters institutionally because it shows that the statutory annual report is capable of disclosing not merely casualty totals but selected information concerning how the conclusion was reached and which investigative tools were unavailable.

The same report records that CENTCOM had 15 additional Yemen incidents still under assessment as of 1 February 2026, which prevents the published annual number from being treated as a final exhaustive casualty census for all U.S. military activity conducted during 2025.

For Iraq and Syria, the report also makes an important attributional distinction because the Combined Joint Task Force–Operation Inherent Resolve publicly treats civilian casualties as coalition effects for strategic and policy purposes rather than routinely separating them by nationality, whereas Section 1057 requires the Department to report casualties attributed specifically to U.S.-operated weapons. Consequently, apparently different command-level and Department-level figures can coexist without necessarily being contradictory, because the underlying attribution rules are not identical.

This illustrates a wider cross-command governance problem: formal Department-wide standardization does not eliminate differences in operational reporting architecture, mission design or attribution practice, and those differences must be explicitly reconciled before comparing commands numerically.

SOUTHCOM exposes the boundary between civilian-harm accountability and campaign accountability

SOUTHCOM's treatment under the 2025 Section 1057 report presents a fundamentally different analytical problem, because the command assessed that no incident in its area of responsibility during 2025 met the Department's threshold for civilian casualties resulting from U.S. military operations, notwithstanding the beginning of a lethal maritime campaign against vessels associated by the Department with designated organizations.

That result is an official civilian-harm determination under the Department's methodology, but it does not independently answer how each person killed was classified, how target status was established in every incident, whether the legal basis for each strike was identical, or whether the campaign reduced the strategic threat it was intended to address. Those questions sit partly within different reporting systems covering targeting authority, operational intelligence, use-of-force law and campaign effectiveness rather than inside the civilian-harm assessment alone.

The first Lead Inspector General report on Operation Southern Spear underscores that distinction because SOUTHCOM told the Inspector General that it could not publicly release the measures of effectiveness by which it assessed the operation, even though the report documents that from September 2025 through March 2026 the U.S. military struck at least 45 small boats, producing 156 people killed or presumed dead.

The report also states that the formal Southern Spear mission statement is classified and that other operational information, including certain details concerning the campaign, is not publicly releasable, while the Lead IG nevertheless reports strategic claims concerning disruption of narcotics flows and adaptation by trafficking organizations.

This does not establish that SOUTHCOM's internal accountability system is defective, because the public record cannot show what classified congressional reporting, targeting documentation, operational legal review or internal metrics contain; it does establish, however, that public civilian-harm reporting and public strategic-effectiveness reporting are not equivalent, and that successful operation of the first cannot be used as proof that the second is adequate.

Congressional visibility is materially greater than public visibility

The architecture is designed around differentiated audiences, and this fact explains part of the apparent transparency deficit. Congress receives reporting under Section 1057, 50 U.S.C. §§1549 and 1550, War Powers mechanisms and operation-specific oversight provisions, while classified annexes can protect intelligence, targeting criteria and operational methods that would be inappropriate for general release.

The public, by contrast, generally sees only the unclassified portions of those instruments, routine command releases, quarterly civilian-harm publications and later Inspector General reporting, which means the public record cannot be assumed to reproduce the complete oversight record available to congressional committees.

That distinction is legitimate but creates a governance dependency: when public disclosure contracts, confidence increasingly rests on the assumption that classified congressional oversight is receiving sufficiently detailed, timely and analytically usable information, and that committees possess the capacity and willingness to challenge inconsistencies that cannot be tested externally.

For that reason, delayed statutory reporting has greater significance than an ordinary communications delay, because the annual Section 1057 report is one of the bridges deliberately created between operationally protected information and democratic oversight. When that bridge arrives late or when the public version omits information that Congress specifically required in unclassified form, the issue is not merely reputational; it concerns the functioning of the statutory oversight mechanism itself.

The Civilian Protection Center of Excellence adds institutional memory but not independent adjudication

The Civilian Protection Center of Excellence, created under the Civilian Harm Mitigation and Response Action Plan and incorporated into DoDI 3000.17, serves as the Department-wide hub for analysis, training, doctrine, data, lessons learned and operational support, with responsibilities that include monitoring civilian-harm trends, supporting command assessment capability and reviewing implementation of earlier recommendations.

Its existence addresses one of the historic weaknesses of decentralized military assessment systems, namely the risk that knowledge generated by one command, conflict or investigative team fails to migrate across the institution, because the Center is expressly designed to aggregate lessons and standardize capabilities.

It is nevertheless important not to overstate its institutional role: the Center is not an external tribunal, independent prosecutor or autonomous casualty-verification body, because it operates within the Department of Defense and supports command and Departmental processes rather than replacing them with external adjudication. The principal value of the Center therefore lies in standardization, professionalization and institutional learning rather than independent legal accountability.

The current architecture is strongest at determining process, weaker at guaranteeing public comparability

The verified framework is sufficiently developed to answer several important questions affirmatively: Department policy requires reports of potential civilian harm to enter a structured process; assessments must consider reasonably available internal and external evidence; assessors should be institutionally separated from direct involvement in the event; cases can be reopened when new information emerges; indications of possible law-of-war or criminal violations trigger separate reporting mechanisms; combatant commands are expected to maintain dedicated assessment capability; and qualifying information should ordinarily be published at least quarterly.

What the framework does not guarantee is identical public visibility across operational theaters, identical investigative opportunity across permissive and non-permissive environments, identical attribution rules across coalition structures, or publication of every piece of information needed to reproduce the Department's conclusion independently.

The commander's discretion to restrict publication for operational security, investigative integrity, privacy or anti-disinformation reasons is operationally defensible, but it also means that the public cannot determine solely from missing data whether information was never collected, remains under assessment, has been classified, was withheld under an authorized exception, or was simply not published on schedule.

That ambiguity is the single most important institutional weakness in the current public architecture because a standardized internal process can coexist with a fragmented external record.

Key judgments

The present U.S. system should not be characterized as lacking a civilian-harm accountability architecture, because Congress, the executive branch and the Department have constructed overlapping mechanisms covering use-of-force authority, civilian-harm assessment, law-of-war reporting, periodic public disclosure, institutional learning and congressional oversight.

The system's most developed component is the civilian-harm assessment process itself, which now possesses a Department-wide evidentiary standard, command-level assessment cells, external-source requirements, reopening procedures and escalation routes where misconduct or legal violations are indicated.

The most important weakness is the translation from internal assessment to public accountability, because security exceptions, differences in command practice, coalition attribution rules and the separation between casualty assessment and campaign-effectiveness measurement mean that the external record can remain too incomplete to reproduce or compare official conclusions.

AFRICOM currently offers the strongest public command-level implementation evidence, CENTCOM's annual reporting demonstrates substantial incident-level analytical detail in selected cases, and SOUTHCOM illustrates the sharpest divide between a formal civilian-casualty determination and the broader evidentiary requirements needed to judge targeting logic and campaign effectiveness.

The legal architecture is therefore neither empty nor sufficient: it provides a credible institutional basis for answering whether civilian harm was assessed and how the process should operate, but it does not ensure that an external reviewer can independently establish who every person killed was, why every strike was legally and operationally justified, and whether the cumulative campaign delivered its stated strategic effect.

What would change the assessment

Publication of AFRICOM's subsequent FY2026 civilian-harm reports with continuous tracking of the five cases open at the end of March would strengthen the judgment that the current reporting discontinuity is administrative rather than structural, while continued absence without an identified withholding basis would increasingly support a finding of degraded implementation.

A public Department or Inspector General record demonstrating that all combatant commands are meeting paragraph 5.3 of DoDI 3000.17 through either command-level or authorized subordinate-command quarterly reporting would materially strengthen confidence in cross-command consistency.

Release of sanitized Southern Spear effectiveness metrics, or a congressional certification describing those metrics without exposing sensitive operational information, would substantially narrow the present separation between civilian-harm accountability and strategic-effectiveness accountability.

Evidence that casualty assessments were systematically excluding material external information, relying on personnel directly involved in the assessed incident, failing to reopen materially challenged cases or bypassing DoDD 2311.01 when credible law-of-war concerns emerged would materially weaken the assessment of institutional robustness.

Conversely, publication of audit evidence showing standardized case handling, reproducible evidentiary standards, complete quarterly tracking and timely Section 1057 compliance across commands would support a stronger conclusion that the present deficiencies are predominantly public-transparency limitations rather than failures of the underlying accountability machinery.

Open official record

The official record reviewed for this chapter does not publicly establish the complete legal rationale, target-identification criteria or strike-by-strike targeting record for Operation Southern Spear, and those elements therefore cannot be reconstructed from the civilian-harm framework alone.

The public record does not yet explain why AFRICOM's public quarterly series currently ends with FY2026 Q2 despite five assessments remaining open at the end of that quarter, and no inference of violation should be made until an official explanation, later publication or documented withholding decision is available.

The official record also does not provide a single consolidated public audit showing whether every geographic combatant command has implemented paragraph 5.3 of DoDI 3000.17 in materially equivalent fashion, which prevents a definitive finding that Department-wide standardization has produced Department-wide public consistency.

Finally, the public record does not establish whether the classified congressional oversight generated under use-of-force statutes contains sufficiently detailed information to resolve the present public gaps concerning targeting status, operational effectiveness and campaign-level causality, because the very nature of that record places substantial portions outside open-source verification.

No decision-useful visualisation is supportable from the verified record, because the relevant architecture is primarily legal and procedural rather than quantitative, while converting command-level reporting differences into a numerical transparency score would require unsupported weighting and would therefore create false precision.

Operational transparency and measurable effectiveness

Principal judgment

The central accountability problem in current U.S. counter-terrorism and counter-designated-terrorist strike operations is not that tactical activity has become impossible to observe, because the official record contains substantial information on strike frequency, targeted organizations, geographic areas, deployed naval and aviation assets, civilian-harm assessment activity and obligated expenditure; the problem is that these observable outputs are not matched by an equivalently transparent body of evidence demonstrating whether the campaigns are changing the operational environment in the direction required by their stated objectives, which produces a widening analytical separation between what U.S. forces are doing and what those actions are demonstrably accomplishing. This distinction corresponds directly to the U.S. military's own assessment logic, under which measures of performance evaluate whether assigned tasks are being accomplished while measures of effectiveness assess whether operations are producing the changes in conditions necessary to achieve objectives and the desired end state, meaning that strike counts, vessels destroyed, sorties generated or money obligated cannot by themselves establish strategic effectiveness even when those figures are accurate and complete. U.S. Army doctrine describes operational assessment as continuous evaluation against both measures of effectiveness and measures of performance, while the Army's doctrinal discussion of those concepts defines performance measures as criteria tied to accomplishment of friendly tasks and effectiveness measures as criteria tied to changes in system behaviour, capability or the operational environment. Measures of Effectiveness in Army Doctrine — U.S. Army

The consequence is particularly important in campaigns whose adversaries are adaptive networks rather than fixed military formations, because destroying a platform, killing an operative or disrupting an individual route is a directly observable tactical result, whereas demonstrating that the operation has durably reduced an organization's ability to regenerate personnel, reroute logistics, substitute transportation modes, replace leadership, finance activity or continue delivering the underlying threat requires a substantially broader assessment architecture. The Department itself recognized this distinction when it adopted the Civilian Harm Mitigation and Response Action Plan, which explicitly connected improved civilian understanding and assessment not merely to humanitarian objectives but to better strategic outcomes and optimized military operations, thereby acknowledging institutionally that tactical execution must ultimately be judged by its effect on the operating environment rather than by activity alone. Civilian Harm Mitigation and Response Action Plan Fact Sheet — U.S. Department of Defense

Southern Spear exposes the distinction between activity and effect with exceptional clarity

Operation Southern Spear provides the clearest current example because its tactical and financial footprint is documented in considerable detail while the command's own strategic measures remain unavailable to the public, creating an unusually direct demonstration of the difference between operational transparency and effectiveness transparency. According to the first Lead Inspector General Report to the United States Congress on Operation Southern Spear, the Department initiated the operation in November 2025 as a mission intended to disrupt narcotics flows from designated terrorist organizations and transnational criminal organizations in the Western Hemisphere, while Joint Task Force Southern Spear became the lead military command under U.S. Southern Command and the formal mission statement itself remained classified. Operation Southern Spear, Report to Congress, January 1, 2026–March 31, 2026 — Department of Defense Office of Inspector General

The operation is therefore far from invisible at the tactical level, because the same official report records that from September 2025 through March 2026 the U.S. military struck at least 45 small boats, resulting in 156 individuals killed or presumed dead, while the force posture supporting the campaign had included the aircraft carrier USS Gerald R. Ford with its embarked air wing, nine Arleigh Burke-class destroyers, two Ticonderoga-class cruisers, three amphibious ships with an embarked Marine Expeditionary Unit, a Freedom-class littoral combat ship, support vessels and P-8 Poseidon maritime patrol aircraft, although SOUTHCOM stated that a complete accounting of personnel and air assets was not publicly releasable. Operation Southern Spear, Report to Congress — Department of Defense Office of Inspector General

Financial visibility is similarly substantial, because SOUTHCOM reported approximately $527.9 million in obligations during January–March 2026 and $647.0 million in cumulative obligations from September 2025 through 31 March 2026, with the quarterly figure comprising $248.8 million for operations, $58.3 million for personnel and $220.8 million for transportation across participating military components and U.S. Transportation Command. Operation Southern Spear, Report to Congress — Department of Defense Office of Inspector General, funding table

Those figures establish that the government can publicly account for important categories of input and output, including resources committed, major platforms deployed, vessels struck and human fatalities associated with those strikes, yet the decisive effectiveness variable remains unavailable because SOUTHCOM told the Inspector General that it could not publicly release the measures of effectiveness used to assess the conduct of Operation Southern Spear. The same report records that General Francis L. Donovan, then Commander of SOUTHCOM, testified to Congress in March that trafficking organizations had adapted to the pressure imposed by the operation by using alternative shipping routes and modalities, specifically increasing reliance on air traffic and shipping containers rather than small boats and shifting transit routes farther west into the Pacific. Operation Southern Spear, Report to Congress — Department of Defense Office of Inspector General, “Effectiveness” section

That official admission of adaptation is analytically decisive because it creates at least two competing interpretations of the same kinetic results, neither of which can be resolved from the strike count alone: one interpretation is that lethal pressure is increasing the expected cost of maritime trafficking sufficiently to deter use of vulnerable small-vessel routes, while the competing interpretation is that trafficking organizations are substituting routes and transport modes without materially reducing the quantity of narcotics ultimately entering the United States, which would mean that tactical suppression of one channel has produced displacement rather than strategic denial. The Department's own senior official offered the first interpretation when Joseph Humire, Performing the Duties of Assistant Secretary of War for Homeland Defense and Americas Security Affairs, told Congress that lethal strikes generated deterrence by raising the risks faced by cartels moving narcotics through the Caribbean and eastern Pacific, whereas General Donovan's testimony concerning displacement toward air traffic, containers and western Pacific routes establishes the countervailing adaptation mechanism within the same official record. Operation Southern Spear, Report to Congress — Department of Defense Office of Inspector General

The campaign's target commodity matters when effectiveness is measured

The strategic measurement problem becomes more demanding when the composition of the U.S. drug market is incorporated, because the official evidence demonstrates that the principal narcotics threats do not move through identical production systems or transportation corridors, which means that a maritime strike campaign cannot validly be assessed against aggregate U.S. drug harm without distinguishing which commodities and routes the operation is structurally capable of affecting. The Drug Enforcement Administration's 2025 National Drug Threat Assessment identifies Colombia as the primary source of cocaine entering the United States, followed by Peru and Bolivia, while explaining that Mexico-based cartels obtain large South American cocaine shipments that can move by sea, air or land through Mexico, Central America and the Caribbean before onward distribution; DEA laboratory analysis further found that approximately 84 percent of domestic cocaine samples seized and analysed in 2024 were of Colombian origin, while wholesale cocaine purity rose from 86 percent in 2023 to 88 percent in 2024. 2025 National Drug Threat Assessment — Drug Enforcement Administration

The same official Southern Spear report, drawing on DEA information, states that fentanyl and methamphetamine consumed in the United States are produced almost entirely in Mexico, that more than 80 percent of cocaine reaching the U.S. market originates in Colombia, and that DEA had received no information indicating that Venezuela was a source of fentanyl or fentanyl precursor chemicals; more importantly for campaign assessment, DEA informed the Inspector General that fentanyl was neither produced in nor trafficked through the countries or shipping lanes constituting the Southern Spear area of operations, while Mexican-produced fentanyl, methamphetamine and heroin typically enter the United States through land transportation and legal ports of entry rather than through the maritime routes being struck. Operation Southern Spear, Report to Congress — Department of Defense Office of Inspector General

This does not demonstrate that Southern Spear cannot affect narcotics trafficking, because cocaine remains a major illicit commodity and maritime routes are materially relevant to its movement, but it does establish that strategic effectiveness must be measured against the specific flows the operation can plausibly influence rather than against an undifferentiated national drug threat, since reductions in cocaine movement through targeted maritime corridors would not by themselves establish an equivalent reduction in fentanyl availability, methamphetamine supply, overdose mortality or total illicit-drug harm within the United States. DEA's own published threat assessment reinforces the point by describing the U.S. drug environment as a heterogeneous market in which synthetic opioids, methamphetamine, cocaine and other substances arise from different production chains and trafficking systems. National Drug Threat Assessment — Drug Enforcement Administration

Expenditure visibility does not provide an efficiency measure without an outcome denominator

The availability of the $647.0 million cumulative Southern Spear obligation figure makes financial scrutiny possible but does not, by itself, permit a defensible calculation of campaign efficiency, because the denominator required for such a calculation remains uncertain and the expenditure base is broader than the direct cost of individual lethal engagements. The official quarterly financial table includes operations, personnel and transportation expenditures across the Air Force, Navy, Marine Corps, Army and U.S. Transportation Command, while the operation simultaneously supports surveillance, force posture, interdiction, mobility, logistics and other mission requirements, which means that simply dividing cumulative obligations by the number of vessels struck or persons killed would create an analytically misleading “cost per strike” or “cost per casualty” measure that neither the Department nor the Inspector General treats as an effectiveness metric. Operation Southern Spear, Report to Congress — Department of Defense Office of Inspector General

A defensible efficiency assessment would instead require an outcome variable tied to the stated strategic objective, such as the volume or value of targeted narcotics denied to trafficking networks, durable reduction in relevant maritime flows, increase in trafficker operating cost, degradation of network throughput, reduction in successful deliveries, measurable deterrence from participation, displacement costs imposed on alternative routes, or a documented change in relevant U.S. wholesale price, purity and availability indicators that could plausibly be attributed to the operation rather than to unrelated enforcement or market developments. Because SOUTHCOM's actual measures of effectiveness remain non-public, the official record does not presently supply enough information to calculate any such ratio without introducing unsupported assumptions. Operation Southern Spear, Report to Congress — Department of Defense Office of Inspector General

AFRICOM presents the opposite pattern: strike activity is unusually visible, strategic effect is much harder to quantify

AFRICOM's public record provides a remarkably clear measure of operational tempo because the command maintains an official strike register identifying dates, approximate locations, targeted organizations and, in some cases, strike classifications, with the register recording 78 strikes during 2026 through 7 August, including operations against al-Shabaab and ISIS-Somalia, after which AFRICOM issued additional official releases confirming al-Shabaab strikes conducted on 4 September, 5 September and 8 September 2026, bringing the minimum number of publicly acknowledged 2026 AFRICOM strikes to at least 81 as of the present assessment, even though the central strike register itself had not yet incorporated those September operations when reviewed. U.S. Africa Command Strike Record and U.S. Africa Command September 2026 releases provide the underlying official record.

The distribution of those strikes also demonstrates that tactical data can be quite granular without resolving the larger effectiveness question, because AFRICOM's register identifies multiple 2026 operations around the Golis Mountains against ISIS-Somalia and an expanding series of operations against al-Shabaab around Jilib, Jamaame, Kismayo, Lower Juba and other areas of southern Somalia, with several June strikes explicitly classified as collective self-defence. U.S. Africa Command Strike Record

AFRICOM explains publicly that its strikes are intended to degrade terrorist organizations' ability to plan and execute attacks threatening the United States, U.S. forces and U.S. citizens abroad, while describing African partner forces as the preferred first line of action against regional terrorist activity; however, the official public strike register does not systematically pair each strike or sequence of strikes with standardized information concerning confirmed fighters killed, leadership attrition, destroyed materiel, reduced attack frequency, territorial denial, organizational regeneration, changes in freedom of movement, disrupted financing, reduced recruitment or the survival of the targeted capability over time. U.S. Africa Command Strike Record and Policy Statement

This difference between an observable strike series and an incomplete strategic-effect series matters because a counter-terrorism organization can suffer repeated tactical losses while maintaining or increasing strategic capability through recruitment, replacement leadership, territorial access, taxation, coercion, local alliances, adaptive logistics or a shift in operational priorities, which means that the numerator “strikes conducted” cannot establish the denominator “terrorist capability removed.” U.S. military doctrine itself warns against confusing task accomplishment with changes in the operational environment, because measures of performance answer whether forces are accomplishing assigned tasks while measures of effectiveness address whether those tasks are producing the conditions required to reach the objective. Measures of Effectiveness in Army Doctrine — U.S. Army

Civilian-harm assessment provides one outcome stream, but it is not a campaign-effectiveness metric

AFRICOM's civilian-harm architecture supplies information that the strike register itself does not, but its analytical purpose must be kept distinct from campaign assessment, because the command's civilian-harm reports are designed to determine whether U.S. operations harmed civilians and to track unresolved allegations rather than to demonstrate whether military pressure has reduced terrorist capability. In its FY2026 second-quarter report covering the period ending 31 March 2026, AFRICOM recorded two new reports of civilian harm, three cases carried over from previous quarters and no assessments closed during the quarter, leaving five assessments open, while explicitly stating that its quarterly process operates pursuant to Department of Defense Instruction 3000.17 and that assessments use publicly available information, intelligence and operational reporting that are not necessarily all accessible outside the government. U.S. Africa Command Civilian Casualty Assessment Report; 2nd Quarter, FY2026

That reporting materially improves accountability because it provides a mechanism for examining the human consequences of operations and for reopening cases when new evidence emerges, yet a finding of no substantiated civilian harm cannot establish that a strike succeeded strategically any more than a substantiated civilian casualty finding automatically establishes that the underlying mission failed strategically. The Department recognized precisely this distinction when it designed its civilian-harm reforms around the proposition that protection of civilians contributes to strategic success but does not itself constitute the entirety of operational assessment, with the 2022 action plan calling for standardized data management, stronger assessment capabilities and incorporation of civilian-environment outcomes into campaign planning. Civilian Harm Mitigation and Response Action Plan — U.S. Department of Defense

The resulting architecture therefore creates two different evidentiary tracks that should not be conflated: civilian-harm assessment asks what consequences U.S. operations imposed on civilians, whereas campaign-effectiveness assessment asks whether those operations changed adversary behaviour, capability and the broader operational environment in a manner advancing the mission's political and military objectives, and only the second question can establish whether sustained kinetic activity is strategically productive.

Asset deployment is an input measure whose opportunity cost belongs inside effectiveness assessment

Southern Spear also demonstrates why force deployment should be treated as an input rather than an accomplishment, because the initial operation involved a force package that included a carrier strike group, multiple destroyers and cruisers, amphibious vessels, a Marine Expeditionary Unit, maritime patrol aircraft and substantial supporting infrastructure, after which the beginning of Operation Epic Fury on 28 February 2026 required the Department to reprioritize major assets toward U.S. Central Command, including the USS Gerald R. Ford carrier strike group that had previously supported operations in the Caribbean. Operation Southern Spear, Report to Congress — Department of Defense Office of Inspector General

This reallocation demonstrates that campaign assessment cannot be confined to whether an individual operation is producing measurable tactical outputs, because high-demand forces have alternative uses across theaters and therefore carry strategic opportunity costs that must be incorporated into any serious effectiveness judgment. A mission that produces observable disruption while requiring disproportionately scarce naval, aviation, intelligence or logistical resources can be operationally successful yet strategically inefficient if the same capabilities generate greater marginal value against competing threats elsewhere, while a relatively inexpensive mission can justify modest tactical effects if those effects impose disproportionate costs on an adversary; the official Southern Spear report does not quantify this opportunity-cost comparison, but the documented reassignment of major assets establishes that the trade-off is real rather than theoretical. Operation Southern Spear, Report to Congress — Department of Defense Office of Inspector General

Adversary adaptation is not automatically evidence of either success or failure

The movement of trafficking organizations toward air routes, containers and more westerly Pacific corridors should therefore be treated as a diagnostic indicator rather than a predetermined conclusion, because displacement can represent either successful coercion or incomplete suppression depending on the costs imposed and the volume ultimately preserved. If alternative routes require longer transit distances, more expensive logistics, more corrupt intermediaries, more detectable infrastructure, reduced shipment frequency or lower payloads, then displacement itself can represent meaningful operational success even if narcotics flows do not cease entirely, whereas displacement becomes much less significant if networks substitute routes rapidly and cheaply while preserving throughput, margins and market availability.

The current official record establishes the adaptation but does not publicly quantify the relevant elasticity, because SOUTHCOM has acknowledged route and modality substitution while withholding its measures of effectiveness, leaving unanswered the key questions of how much additional cost the adaptation imposes, whether shipment success rates have fallen, whether total relevant narcotics throughput has declined, whether traffickers require larger inventories or longer cycle times, and whether U.S. domestic market indicators reflect scarcity attributable to the operation. Operation Southern Spear, Report to Congress — Department of Defense Office of Inspector General

The same analytical principle applies to AFRICOM operations against terrorist organizations, because leadership replacement, movement from one district to another, temporary reductions in attack tempo or dispersal of forces can each represent meaningful pressure without necessarily representing durable strategic degradation, while an adversary's continued ability to regenerate, tax populations, recruit fighters, exploit political vacuums or resume attacks after a temporary reduction would weaken the inference that repeated strikes are changing the long-term security environment.

Transparency should therefore be assessed across an evidence chain rather than by counting press releases

A decision-grade transparency standard should distinguish at least five layers of evidence because each answers a different question: input transparency establishes what resources and authorities were committed; activity transparency establishes what forces actually did; immediate-effect transparency establishes what targets, people or materiel were affected; operational-outcome transparency establishes whether adversary capability or behaviour changed; and strategic-effect transparency establishes whether those changes advanced the policy objective strongly enough to justify the costs and second-order consequences. Southern Spear currently provides comparatively strong public evidence at the first two layers, partial evidence at the third, limited public evidence at the fourth and insufficient public evidence at the fifth, while AFRICOM provides an unusually detailed activity series and a formal civilian-harm outcome stream but no equivalently standardized public series connecting its high strike tempo to long-term changes in al-Shabaab or ISIS-Somalia capability. Operation Southern Spear, Report to Congress — Department of Defense Office of Inspector General and U.S. Africa Command Strike Record provide the principal official records for those two theaters.

This architecture explains why an operation can appear highly transparent when measured by frequency of official announcements yet remain difficult to evaluate strategically, because publishing every strike date would still leave the central causal question unanswered if the government did not also disclose enough information to establish how the adversary's relevant capability changed and whether that change endured.

The public record therefore supports tactical accounting more strongly than strategic attribution

The verified evidence supports a relatively strong conclusion that U.S. commands can count and disclose substantial categories of operational activity, but it supports a much weaker conclusion concerning public attribution of strategic outcomes to those activities, because the causal chain between a strike and a policy objective becomes progressively more difficult to establish as the analysis moves from immediate physical effects toward network behaviour, market conditions, territorial control, recruitment dynamics and long-term political outcomes. The Department's own civilian-protection reforms acknowledge the necessity of learning and data integration precisely because tactical and operational success can fail to translate into strategic success when the broader environment reacts adversely or the adversary adapts. Civilian Harm Mitigation and Response Action Plan Fact Sheet — U.S. Department of Defense

For Southern Spear, the most important missing bridge is the undisclosed set of SOUTHCOM effectiveness measures capable of establishing whether the combination of lethal pressure, interdiction and deterrence has reduced the targeted narcotics flows rather than merely redistributed them; for AFRICOM, the corresponding missing bridge is a standardized public series connecting strike tempo to observable changes in terrorist attack capability, freedom of movement, leadership regeneration, territorial access and partner-force security performance over a sufficiently long period to distinguish temporary disruption from durable degradation. Neither gap requires disclosure of targeting sources, intelligence methods, platform capabilities or individual operational plans, because aggregate outcome measures can in principle be released at a level that preserves operational security while still allowing institutional scrutiny, although the present official record does not establish which specific aggregate metrics the commands have determined can safely be declassified.

A defensible effectiveness framework requires the denominator to follow the mission

The principal measurement requirement is therefore straightforward in concept even though difficult in implementation: each campaign's tactical outputs must be tested against indicators derived from its stated objective rather than against convenient activity measures, because military doctrine treats assessment as progress toward an end state rather than accumulation of completed actions. For Southern Spear, this would require longitudinal evidence on targeted narcotics throughput, displacement cost, trafficking success rates, modal substitution, relevant wholesale market availability and network regeneration rather than only vessel strikes and fatalities; for AFRICOM, it would require longitudinal evidence on adversary attack capacity, operational reach, command regeneration, territorial and logistical access, partner-force resilience and the durability of any changes following sustained kinetic pressure. U.S. Army operational-assessment doctrine explicitly frames assessment around continuous monitoring of progress toward the desired end state and evaluation against both performance and effectiveness measures.

The absence of such public measures does not establish that the Department lacks them internally, and the Inspector General's statement that SOUTHCOM would not publicly release its measures of effectiveness in fact establishes that at least some formal measurement structure exists inside the command; the narrower and more defensible conclusion is that external observers cannot currently reproduce the command's effectiveness judgment or determine whether its metrics adequately capture substitution, adaptation, second-order effects and opportunity costs. Operation Southern Spear, Report to Congress — Department of Defense Office of Inspector General

Key judgments

The official record supports the conclusion that operational activity is substantially more transparent than strategic effectiveness, because Southern Spear's strikes, fatalities, force posture and obligations are publicly measurable while SOUTHCOM's formal effectiveness metrics are not, whereas AFRICOM provides a detailed strike series and structured civilian-harm reporting without an equivalently standardized public series demonstrating the durable effect of that strike tempo on terrorist capability. Operation Southern Spear, Report to Congress — Department of Defense Office of Inspector General and U.S. Africa Command Strike Record establish the respective public baselines.

The 45 or more vessels struck, 156 killed or presumed dead and $647.0 million obligated through March 2026 are therefore valid measures of the scale and intensity of Southern Spear but cannot independently establish that the operation has reduced the relevant narcotics threat, particularly because the command itself reports adversary migration toward alternative routes and transportation modes and because DEA evidence demonstrates that the principal U.S. drug threats arise through materially different supply chains. Operation Southern Spear, Report to Congress — Department of Defense Office of Inspector General and 2025 National Drug Threat Assessment — DEA provide the controlling official evidence.

AFRICOM's at least 81 publicly acknowledged strikes during 2026 through 8 September establish a high operational tempo, but strike frequency remains a performance measure rather than proof of strategic degradation unless it can be connected to persistent changes in al-Shabaab and ISIS-Somalia behaviour, capability and freedom of action. U.S. Africa Command Strike Record and U.S. Africa Command September releases provide the underlying official record.

The strongest current evidence concerning Southern Spear's strategic effect is therefore not the number of targets destroyed but the documented behavioural adaptation of trafficking networks, although the direction of that evidence remains ambiguous because the public record does not establish whether substitution toward containers, aircraft and western Pacific routes is sufficiently costly to reduce overall throughput or merely represents economically manageable displacement. Operation Southern Spear, Report to Congress — Department of Defense Office of Inspector General

What would change the assessment

Publication of SOUTHCOM's sanitized measures of effectiveness, particularly if they included longitudinal evidence on relevant narcotics volumes, shipment success rates, route substitution, trafficking cost, network regeneration and domestic availability indicators, would materially narrow the present accountability gap because it would permit the public record to move from measuring kinetic activity toward testing strategic causality.

Evidence showing that route and modal substitution has imposed sufficiently large costs to reduce overall targeted narcotics throughput, compress trafficking margins, reduce shipment frequency or produce sustained scarcity in relevant U.S. markets would strengthen the judgment that Southern Spear is generating strategic rather than merely tactical effect, whereas evidence showing stable or rising throughput despite migration to alternative channels would strengthen the displacement hypothesis.

For AFRICOM, a standardized official series demonstrating sustained reductions in al-Shabaab or ISIS-Somalia attack capacity, operational reach, leadership regeneration, territorial freedom and coercive financing following the current strike campaign would materially strengthen the inference that high strike tempo is producing durable degradation, whereas continued adversary expansion or stable capability despite repeated strikes would weaken that inference even if individual operations remained tactically successful.

A Department-wide system that consistently linked resources, actions, immediate effects, operational outcomes and strategic objectives would materially improve auditability across theaters because it would make clear where the causal chain is supported by evidence and where judgment still depends on classified information or unresolved attribution.

Open official record

The official public record does not disclose SOUTHCOM's actual Operation Southern Spear measures of effectiveness, their baseline values, thresholds, weighting, collection methods or assessment intervals, which prevents external replication of the command's strategic-effectiveness judgment despite comparatively strong visibility into expenditure and tactical activity. Operation Southern Spear, Report to Congress — Department of Defense Office of Inspector General

The official record reviewed for this chapter does not provide a sufficiently current, methodologically compatible series for cocaine availability, price, purity and overall U.S.-bound throughput extending through the full Southern Spear period, so no claim that the operation has increased or reduced domestic narcotics availability can presently be made from verified official evidence.

The official AFRICOM record establishes strike occurrence and civilian-harm assessment activity but does not publish a standardized longitudinal campaign-effectiveness dataset capable of connecting the current strike rate to durable changes in terrorist organizational capacity, which prevents a defensible numerical estimate of strategic effect.

No decision-useful visualisation is supportable from the verified record at this stage, because the available official variables measure different analytical levels — expenditure, platforms, strikes, fatalities, unresolved civilian-harm assessments and adversary adaptation — while the decisive effectiveness denominators remain undisclosed or definitionally incomplete, meaning that combining the available figures into a single chart, score or efficiency ratio would create false comparability rather than improve understanding.

Governance consequences and decision thresholds

Principal judgment

The decisive governance question is not whether the United States should disclose classified targeting intelligence, operational plans, sources, methods, rules of engagement, surveillance capabilities or other information whose release could endanger forces and compromise future operations, because both law and sound military practice permit substantial secrecy around those matters; the controlling institutional question is whether Congress, Inspectors General and ultimately the public can obtain enough aggregated, sanitized and methodologically intelligible evidence of effectiveness to determine whether increasingly costly kinetic campaigns are accomplishing the objectives for which funds, authorities and scarce military capabilities are being committed. The verified record now demonstrates why that distinction matters, because the second Lead Inspector General report on Operation Southern Spear shows that by 30 June 2026 cumulative reported costs had reached approximately $820.9 million, while at least 19 additional vessels were struck during April–June, causing an estimated 56 people to be killed or presumed dead, even though significant aspects of the mission and targeting architecture remained classified and SOUTHCOM had previously declined to make its effectiveness measures publicly available. Operation Southern Spear, Report to Congress, April 1–June 30, 2026 — Department of Defense Office of Inspector General

The resulting governance problem is therefore one of asymmetric observability, because expenditure, force posture and tactical activity can increasingly be counted while the causal bridge connecting those inputs to strategic effect remains substantially less visible, which means that appropriators can know how much an operation costs without necessarily being able to determine from the public record what measurable improvement those expenditures purchased, policymakers can know how many targets were struck without being able to determine whether the adversary's relevant capability has durably declined, and civilian-harm assessors can determine whether particular operations crossed a casualty threshold without answering whether the campaign itself remains the most effective available instrument for achieving the underlying policy objective. This distinction is consistent with the Department's own governance philosophy under DoDI 3000.17, which explicitly states that civilian-harm mitigation supports long-term strategic success, operational effectiveness and legitimacy, while requiring the Department to identify, document and disseminate lessons rather than treating completion of military activity as equivalent to achievement of strategic objectives. DoD Instruction 3000.17, Civilian Harm Mitigation and Response — Department of Defense

Classification is compatible with oversight, but secrecy cannot substitute for evaluation

The public-versus-classified distinction must be handled carefully because the mere fact that an effectiveness metric is classified does not establish an accountability failure, particularly where disclosure would reveal adversary-sensitive intelligence, collection capabilities, targeting methodologies, operational thresholds or vulnerabilities that could enable adaptation; Congress routinely conducts national-security oversight using classified reporting, closed hearings and restricted annexes, while Inspectors General are legally empowered to examine information that cannot safely be released publicly, meaning that democratic oversight does not require universal disclosure. The critical threshold is crossed only when classification or operational-security restrictions prevent the relevant oversight institution from obtaining sufficiently specific evidence to determine whether a programme or operation is effective, economical and consistent with its authorization, because secrecy is then no longer protecting the means by which policy is implemented but begins to obstruct assessment of whether the policy itself is working.

The statutory Lead Inspector General architecture illustrates precisely how Congress attempted to avoid that outcome, because 5 U.S.C. §419 requires the Lead Inspector General for a qualifying overseas contingency operation to develop a joint strategic plan for comprehensive oversight, ensure independent and effective audits, inspections and investigations, review the accuracy of federal information concerning obligations, expenditures and programme costs, and submit recurring reports to Congress while making specified reporting publicly available. The statute therefore treats financial accounting and programme-effectiveness oversight as related but distinct functions, which means that accurate expenditure figures are necessary but not sufficient for institutional accountability. 5 U.S.C. §419 — Special provisions concerning overseas contingency operations

Operation Southern Spear now falls squarely inside that architecture, because the Department's Office of Inspector General identifies the operation as subject to Lead Inspector General reporting and has issued successive quarterly reports covering January–March and April–June 2026, while the governing statute additionally requires the Lead Inspector General to ascertain the accuracy of agency information concerning obligations, expenditures, programme costs and accountability of funds. The significance of this structure is that Congress did not create the Lead IG merely to count spending or catalogue military activity; it created an independent oversight mechanism capable of testing the relationship between resources, execution and results. Operation Southern Spear — Department of Defense Office of Inspector General, July 2026

The latest Southern Spear record makes the governance tension sharper rather than weaker

The April–June 2026 Lead IG report materially advances the public record because it shows that the campaign continued at substantial kinetic intensity even as the force package and expenditure profile changed: U.S. forces struck at least 19 suspected designated-terrorist-organization vessels during the quarter, compared with 12 during January–March, while the estimated number killed or presumed dead increased from 40 to 56; at the same time, the overall maritime presence declined, several major vessels departed the joint operations area, and quarterly SOUTHCOM-reported obligations fell to approximately $173.9 million, which the command attributed to transition toward steady-state operations and departure of personnel and ships. Operation Southern Spear, April–June 2026 — Lead Inspector General Report to Congress

This combination is analytically important because it demonstrates why tactical productivity cannot be inferred from spending alone and why spending cannot be interpreted without an outcome denominator, since a quarter containing more strikes and fatalities but substantially lower reported obligations might indicate improved operational efficiency, a change in force composition, a shift toward less expensive strike platforms, the maturation of the campaign into steady-state activity, or merely the transfer of major costs outside the period or accounting categories being compared; the official report itself introduces an additional accounting complication by noting that SOUTHCOM reported $173.9 million in quarterly obligations while the Office of the Under Secretary of Defense (Comptroller)/Chief Financial Officer reported $211.44 million as of 16 June, which means even the expenditure denominator requires definitional care before any efficiency calculation can be defended. Operation Southern Spear, Funding section — Department of Defense Office of Inspector General

The appropriate governance conclusion is consequently not that Congress should demand publication of a simplistic “cost per target” ratio, which would reward activity rather than strategy, but that appropriators require enough classified and, where possible, sanitized evidence to understand whether expenditure is producing changes in the conditions that motivated the operation, whether those changes persist after forces are reduced, whether adversaries are merely substituting routes and methods, and whether the marginal strategic return from additional expenditure exceeds the opportunity cost of using the same military capabilities elsewhere.

Congress cannot assess value for money from obligations and strike counts alone

The constitutional and statutory budget architecture reinforces this requirement because the federal budgeting process is not conceptually limited to accounting for outlays, with 31 U.S.C. §1105 requiring the President's budget submission to contain information on government activities and functions and, where practicable, information on the costs and achievements of government programmes, which reflects the wider federal principle that financial authorization and performance evidence are analytically connected even though classified military activities necessarily require specialized treatment. 31 U.S.C. §1105 — Budget contents and submission to Congress

The same principle is reflected more generally in federal performance law, under which agency planning is organized around objectives and measurable performance rather than expenditure alone, while the Government Accountability Office has repeatedly treated the absence of explicit goals, desired outcomes and performance metrics as a barrier to effective oversight; in its review of Defense intelligence and security governance, GAO concluded that an organization without adequate performance tools could not fully assess whether its enterprises were achieving strategic objectives, and by July 2026 GAO reported that the Department had implemented one of its recommendations through an annual performance plan and automated mechanism tracking progress toward strategic goals. Although that case concerns intelligence and security governance rather than Southern Spear directly, the institutional principle is highly relevant because it demonstrates that the federal oversight standard itself recognizes that accountability requires defined outcomes and performance metrics, not merely proof that authorized activity occurred. Defense Intelligence and Security: DOD Needs to Establish Oversight Expectations and Develop Tools That Enhance Accountability — U.S. Government Accountability Office

For Congress, this creates a clear appropriations threshold: expenditure information remains decision-useful only when legislators can relate the money being requested or obligated to a defined mission, an observable baseline and a measure of progress that distinguishes activity from achievement, because otherwise the appropriations process risks becoming a retrospective authorization of operational tempo rather than an assessment of the marginal value created by further spending.

The first decision threshold is whether Congress itself receives the full effectiveness architecture

The lowest and least controversial threshold should therefore concern congressional access rather than public release, because if SOUTHCOM maintains classified measures of effectiveness, the first governance requirement is that the relevant authorization, appropriations and oversight committees receive those metrics together with their definitions, baselines, collection methods, confidence limitations and evidence of adversary adaptation, so that elected oversight institutions can evaluate the campaign without forcing sensitive information into the public domain. This arrangement preserves operational secrecy while protecting congressional capacity to determine whether strategic claims are supported by evidence.

The public official record presently establishes that SOUTHCOM has measures of effectiveness but previously declined to release them publicly, while the latest Lead IG reporting does not provide their complete methodology; accordingly, the open-source record cannot establish whether Congress has received the full internal metric set through classified channels, and that distinction must remain explicit because absence of public disclosure cannot be treated as evidence that congressional oversight is equally uninformed. Operation Southern Spear — Department of Defense Office of Inspector General

If relevant committees receive the metrics, underlying methodology and trend evidence on a timely basis, the governance deficit is principally one of public accountability and external reproducibility; if committees receive only operational summaries, strike counts or assertions of success without the underlying effectiveness architecture, the deficit becomes materially more serious because Congress's constitutional spending and authorization functions would be exercised without access to the evidence required to evaluate strategic return.

The second threshold is whether a sanitized public effectiveness layer can be produced safely

The next decision threshold concerns what can reasonably be released outside the classified oversight environment, because there is a significant analytical difference between publishing the intelligence that identifies individual targets and publishing aggregate indicators showing whether the campaign is achieving its purpose. A sanitized public layer could, without revealing individual sources or tactics, report trends such as changes in illicit maritime activity, changes in interdiction volumes, route substitution, modal substitution, reconstitution rates, estimated trafficking cost increases, percentage changes in relevant flows or other aggregated indicators whose definitions and comparison periods are explicit enough to allow scrutiny.

The Department has already demonstrated in adjacent domains that sensitive operations can coexist with aggregated public reporting, because DoDI 3000.17 directs combatant commands to publish qualifying civilian-harm information at least quarterly while permitting withholding where disclosure would compromise classified information, reveal tactics or patterns, interfere with investigations or create other specified risks; the policy therefore embodies the institutional principle that operational security and public accountability are not binary alternatives, because information can be aggregated, delayed or narrowed rather than either fully disclosed or completely withheld. DoD Instruction 3000.17, Civilian Harm Mitigation and Response

That same logic can be applied to effectiveness reporting without assuming that every measure suitable for internal command use is suitable for public release, because a public metric need not reproduce the classified operational model; it needs only to provide enough evidence to establish the direction, scale and persistence of strategic effect while preserving sensitive inputs.

The third threshold is methodological reproducibility rather than numerical abundance

A public effectiveness measure becomes decision-useful only when its meaning can be understood and reproduced at least conceptually, because percentages without a defined baseline, geography, denominator, time period or collection method can create an appearance of precision while remaining analytically non-auditable. A statement that maritime trafficking activity has fallen by a certain percentage, for example, would require at minimum a definition of what counts as “activity,” the geographic sector being measured, the baseline period, whether the metric records detected or estimated traffic, how intelligence gaps are treated, and whether migration toward air, container or land routes is included in the denominator rather than disappearing from the measurement universe.

This requirement becomes especially important because the latest Lead IG report records that experts observed traffickers shifting toward land routes through Central America and cocaine concealed in container ships, while the U.S. Coast Guard separately reported 25 interdictions during April–June that seized nearly 21 tons of cocaine and detained 45 suspected smugglers, alongside a reported 36 percent decline in Coast Guard drug seizures during the first two quarters of FY2026 compared with the corresponding FY2025 period, even though the Coast Guard stated that its interdiction activities had not changed since Southern Spear began. These figures are highly relevant indicators, but none alone determines whether the military campaign reduced total trafficking because detection effort, route displacement, successful undetected shipments and market adaptation remain potential confounders. Operation Southern Spear, April–June 2026 — Lead Inspector General Report to Congress

The decision threshold should therefore be methodological rather than cosmetic: if an aggregate indicator cannot be interpreted without classified assumptions that fundamentally determine its meaning, Congress may still rely on the classified version, but the public version should not be presented as an independently verifiable measure of strategic success.

The fourth threshold is whether adversary adaptation is inside the effectiveness metric

The strongest evidence that a kinetic campaign requires multidimensional assessment is the documented ability of trafficking networks to substitute routes and methods, because a campaign that suppresses one transport channel can simultaneously produce tactical success and strategic displacement, and the difference between those outcomes cannot be determined unless adaptation appears explicitly inside the assessment framework. The April–June Lead IG report again records alternative smuggling methods, including land routes and containerized cocaine, while the earlier report documented movement toward aircraft and Pacific routes, demonstrating that substitution is not a theoretical critique but an observed feature of the operating environment. Operation Southern Spear, April–June 2026 — Department of Defense Office of Inspector General

An effectiveness framework that counts only the targeted channel therefore risks producing a false positive, because the metric can improve precisely when the adversary has successfully moved activity outside the area being measured; accordingly, the governance threshold should require either an all-route effectiveness measure or an explicit displacement adjustment that distinguishes elimination, deterrence, diversion and substitution rather than treating them as equivalent forms of success.

The fifth threshold is whether tactical success remains strategically economical

The financial profile of Southern Spear makes marginal-effect analysis unavoidable because cumulative SOUTHCOM-reported expenditure reached approximately $820.9 million by the end of June 2026, while the Lead IG framework itself remains tied to appropriated resources and, under 5 U.S.C. §419, continues until the statutory sunset condition is reached in a fiscal year in which total appropriations for the operation fall below $100 million. This linkage between appropriations and oversight is institutionally important because it recognizes that sustained expenditure generates a continuing requirement for independent scrutiny rather than allowing the oversight architecture to disappear while a major contingency remains materially funded. 5 U.S.C. §419 — Special provisions concerning overseas contingency operations

The relevant decision threshold for Congress is therefore not a fixed dollar amount at which an operation becomes “too expensive,” because such a threshold would ignore the strategic value produced, but whether the marginal cost of continuing or expanding the campaign can be connected to an observable incremental effect after accounting for adversary adaptation, displacement and alternative uses of the same forces. An operation whose costs decline while strategic effect persists may be becoming more efficient, whereas an operation whose expenditure rises while adversary capability and threat indicators remain unchanged would require progressively stronger justification, and neither judgment can be reached from expenditure figures alone.

Opportunity cost belongs inside the governance calculation

The requirement for an effectiveness denominator becomes still stronger when the military resources involved are scarce and globally deployable, because the April–June Lead IG report shows that the Southern Spear force structure changed materially from the opening phase while several vessels were subsequently redirected for other missions, and the earlier report documented the movement of major assets out of the theater as other global requirements intensified. The governance implication is that the relevant cost is not only what the Treasury spends but also the strategic opportunity cost of assigning high-demand naval, ISR, aviation and logistics capabilities to one mission rather than another, which becomes increasingly material during periods of simultaneous global contingencies. Operation Southern Spear, Assets Deployed — Lead Inspector General Report to Congress

Congressional scrutiny should therefore distinguish between missions that require capabilities uniquely suited to the task and missions that employ scarce military assets where law-enforcement, partner-force or lower-cost military alternatives might generate comparable outcomes, because an operation can remain tactically effective while becoming strategically inefficient when the value of those forces elsewhere rises.

Independent oversight becomes more important as public transparency narrows

The current architecture contains an important institutional safeguard because the Lead Inspector General is not limited to accepting command-level assertions and has begun examinations that go directly to the integrity of the targeting and intelligence processes underpinning Southern Spear. The April–June report states that the Department OIG launched an evaluation to determine whether SOUTHCOM and subordinate components complied with the Department's established six-step Joint Targeting Cycle, together with a separate evaluation examining the effectiveness of intelligence, surveillance and reconnaissance processing, exploitation and dissemination supporting SOUTHCOM requirements. Operation Southern Spear, Ongoing Oversight Projects — Department of Defense Office of Inspector General

Those examinations are governance-critical because they move oversight from the question of what the command says happened toward the question of whether the processes generating targeting and intelligence judgments functioned as required, while the Lead IG's statutory mandate separately requires independent and effective audits, inspections and investigations across programmes supporting the contingency. If public effectiveness data remain limited, the credibility of these independent review channels therefore becomes more important rather than less, because classified operations require stronger institutional substitution for the external scrutiny that secrecy necessarily prevents. 5 U.S.C. §419 — Lead Inspector General responsibilities

Decision thresholds for Congress and the executive branch

Decision threshold	Evidence required before crossing the threshold	Institutional response if evidence is adequate	Response if evidence remains inadequate
Continuation of current operational tempo	Classified effectiveness measures showing defined objectives, baseline conditions, measurable trend and treatment of displacement	Continue operations with periodic classified and sanitized aggregate reassessment	Require remedial reporting before treating increased tactical activity as evidence of strategic progress
Material increase in appropriations	Demonstrable relationship between additional resources and expected marginal strategic effect, including opportunity cost	Fund against explicit outcome milestones rather than strike-volume milestones	Condition or phase additional funding until outcome measures become decision-useful
Expansion into new geography or operational modality	Evidence that existing operations are producing strategic rather than merely geographic displacement, together with legal and operational assessment	Authorize expansion only where the causal mechanism and expected incremental benefit are established	Avoid converting displacement into automatic mission expansion without evidence that broader force use changes the underlying threat
Reduction of independent oversight	Sustained record of reliable reporting, reconciled financial data and completed OIG evaluations	Permit oversight intensity to decline only as risk, expenditure and operational activity materially decline	Preserve or strengthen Lead IG and committee scrutiny where expenditure or kinetic activity remains material
Public withholding of effectiveness information	Specific operational-security rationale and confirmation that Congress receives the complete underlying assessment	Maintain classification while publishing sanitized trends where feasible	Require an aggregate public layer or an explanation of why even aggregation would create material operational risk
Declaration of strategic success	Persistent outcome evidence demonstrating reduced adversary capability or reduced targeted threat rather than activity displacement	Transition toward lower-cost sustainment, law enforcement or partner-led mechanisms	Treat tactical success as provisional and continue testing alternative explanations

The table deliberately avoids numerical scores because neither statute nor verified official policy establishes a universal quantitative threshold for these judgments, while assigning arbitrary values would produce precisely the false precision that decision-grade oversight should prevent.

Funding conditions are a governance instrument, not an operational verdict

Congress's constitutional control over appropriations gives it a mechanism to compel information without requiring it to substitute itself for military command, because the Appropriations Clause requires Treasury expenditures to rest on appropriations made by law and congressional appropriations legislation can define conditions governing the availability and use of funds within constitutional limits. The Congressional Constitution Annotated explains that the Appropriations Clause gives Congress control over the terms on which public funds are made available, which means that reporting conditions can function as an accountability mechanism without Congress needing to dictate individual targeting decisions. Appropriations Clause — Constitution Annotated, Congress.gov

The proportionate policy instrument would therefore be conditional information requirements rather than automatic operational prohibition, because Congress could require timely classified effectiveness reporting, sanitized public indicators where practicable, reconciled expenditure data and independent OIG validation as conditions attached to specified future funding increments, while preserving emergency authorities or narrowly structured waivers where disclosure to Congress on the original timetable would create an identifiable operational risk. Such a structure would preserve executive flexibility while ensuring that continued expenditure cannot indefinitely outrun the evidence used to justify it.

The executive branch also has an institutional interest in sanitized disclosure

The accountability question should not be framed solely as Congress constraining the executive branch, because the executive itself benefits from producing a defensible public effectiveness layer where operational security permits, particularly when operations generate significant expenditure, civilian-harm allegations, allied concerns or legal controversy. Sanitized metrics can reduce the risk that tactical outputs become the only publicly measurable definition of success, protect operational credibility against unsupported external claims and allow the Department to demonstrate that internal learning mechanisms are connected to strategic outcomes rather than merely procedural compliance.

DoDI 3000.17 already embeds a comparable learning logic by requiring the Department to aggregate information across incidents, disseminate lessons and incorporate findings into doctrine, planning, operational processes, training and tactics, while explicitly linking civilian protection with long-term strategic success and military effectiveness; extending an analogous approach to campaign-effectiveness reporting would therefore not represent an alien transparency doctrine but a governance application of principles the Department already uses in another sensitive operational domain. DoD Instruction 3000.17 — Civilian Harm Mitigation and Response

The decisive institutional boundary is between protecting operational secrets and protecting policy claims from scrutiny

The appropriate governance standard is consequently not maximum disclosure but minimum sufficient auditability, under which the Department retains the ability to protect target-specific intelligence, collection capabilities, operational techniques and other genuinely sensitive information while Congress receives enough underlying evidence to test strategic claims and the public receives enough sanitized information to distinguish measurable outcomes from assertions. An accountability regime fails not when sensitive facts remain secret, but when secrecy prevents the competent oversight institution from determining whether objectives were achieved, how much they cost, what alternative explanations remain plausible and whether the same or better outcome could be obtained through a less costly or less risky instrument.

The second Southern Spear Lead IG report materially strengthens the case for applying that standard because the operation had accumulated approximately $820.9 million in SOUTHCOM-reported costs by 30 June, continued to generate substantial strike activity while moving into a lower-cost steady-state posture, showed documented evidence of trafficking adaptation, and simultaneously triggered OIG evaluations of both the Joint Targeting Cycle and ISR processing architecture, which means that the operation had evolved from an initial tactical intervention into a sustained programme requiring institutionalized performance scrutiny.

Key judgments

The principal governance risk is not classification itself but classification without an adequate substitute accountability mechanism, because sensitive operational information can legitimately remain restricted while classified congressional reporting, Inspector General access and sanitized public metrics together preserve the ability to test whether policy is producing measurable results.

The existing Lead Inspector General framework provides a significant safeguard because 5 U.S.C. §419 requires independent oversight, review of obligations and expenditures, comprehensive oversight planning and recurring reporting to Congress, while the Southern Spear OIG programme has already expanded beyond financial reporting into evaluations of targeting-cycle compliance and ISR effectiveness. 5 U.S.C. §419 — Special provisions concerning overseas contingency operations

The fiscal accountability requirement has become more significant because SOUTHCOM reported approximately $820.9 million in cumulative costs through June 2026, while the quarter simultaneously recorded a higher number of vessel strikes despite substantially lower quarterly spending, demonstrating that activity and cost can move in opposite directions and therefore cannot serve as substitutes for an outcome measure.

The minimum decision-grade standard should therefore require a classified congressional effectiveness layer, an independently reviewable OIG layer and a sanitized public layer wherever operational security permits, with the public component providing definitions, baselines, time periods and treatment of adversary adaptation sufficiently clearly to prevent activity metrics from being mistaken for strategic outcomes.

Funding expansion should become progressively harder to justify when expenditure rises but measurable strategic effects cannot be demonstrated, whereas persistent effects achieved with declining cost and declining force requirements would support a stronger inference of improving efficiency, provided that apparent gains are not created by displacement outside the measured domain.

What would change the assessment

Publication or congressional confirmation of a complete Southern Spear effectiveness framework containing explicit baselines, outcome indicators, methodology, displacement adjustments and confidence limitations would materially strengthen the judgment that the existing accountability architecture is capable of evaluating the campaign even if substantial portions remain classified.

Completion of the OIG evaluations examining the Joint Targeting Cycle and ISR processing, exploitation and dissemination would materially affect this assessment because findings demonstrating consistent compliance, reliable intelligence processing and effective internal controls would strengthen confidence in the operational decision chain, whereas findings of systemic process failures would shift the governance problem from transparency toward substantive institutional performance. Operation Southern Spear, Ongoing Oversight Projects — Lead Inspector General Report

A publicly releasable aggregate series showing that trafficking displacement is accompanied by durable reductions in total targeted narcotics throughput, increased trafficking costs or reduced network capability would strengthen the effectiveness case, while evidence that alternative routes preserve overall supply at manageable additional cost would weaken it even if vessel-strike performance remained tactically successful.

A persistent inability to reconcile command and Comptroller cost figures, continued public reliance on tactical activity in place of strategic outcomes, or confirmation that relevant congressional committees are not receiving the classified effectiveness evidence necessary to evaluate the operation would materially weaken the assessment of current governance adequacy.

Open official record

The verified public record does not establish the full content of SOUTHCOM's classified effectiveness measures, the exact baseline against which those measures are calculated, the frequency with which senior civilian leadership reviews them, the extent to which they incorporate route substitution and modal displacement, or whether the relevant congressional committees receive those metrics in complete form, so no stronger judgment regarding the adequacy of classified congressional oversight is supportable at this stage.

The record also does not yet contain the completed findings of the OIG evaluations of the Southern Command Joint Targeting Cycle or ISR processing architecture, which means that the existence of those oversight projects should be treated as evidence that independent scrutiny is active rather than as evidence that the underlying targeting and intelligence processes have been validated.

The record further contains different quarterly obligation figures from SOUTHCOM and the Department's Comptroller, $173.9 million and $211.44 million respectively, with different reporting dates and apparent accounting scope, and those figures should therefore remain separate until an official reconciliation establishes whether the divergence reflects timing, coverage or another accounting distinction rather than error.

No single decision-useful visualisation is supportable without imposing an artificial common scale on financial expenditure, strike activity, interdictions, casualties, force posture and trafficking adaptation, while the central strategic denominator remains partly classified; the appropriate analytical instrument at this stage is therefore the decision-threshold matrix above rather than a numerical score, risk dial or synthetic effectiveness index.
