ABSTRACT
The confrontation over foreign troop deployments in Ukraine, culminating in Vladimir Putin’s remarks at the 10th Eastern Economic Forum (EEF) in Vladivostok on September 5, 2025, has hardened into a structural impasse where geopolitical red lines, legal constraints, and institutional mechanisms intersect to foreclose reconciliation. This abstract synthesizes the six analytical chapters presented in this study, drawing on primary documentation from the Kremlin, NATO, the United Nations (UN), the Organization for Security and Co-operation in Europe (OSCE), the European Union (EU), and the G7, along with statutory texts from the Verkhovna Rada of Ukraine. By integrating doctrinal positions, legal frameworks, and verified financial and military data updated through September 2025, the abstract highlights the incompatibility of Western and Russian security architectures, the erosion of neutral venues, and the weaponization of discourse as deterrence. The narrative demonstrates that future security arrangements in Ukraine can only evolve within the constrained choices of Western externalized assistance, Russian treaty-based preconditions, institutional paralysis of peacekeeping, or long-term armistice freezes.
At the heart of this confrontation is the Russian doctrine that any foreign troops in Ukraine would be “legitimate targets,” a position officially articulated by Putin at the EEF plenary session and published in the Kremlin’s transcript (Plenary session of the 10th Eastern Economic Forum – September 5, 2025). This red line is not an isolated declaration but the culmination of a doctrine codified in the Foreign Policy Concept of the Russian Federation, approved by decree No. 229 on March 31, 2023, which identifies NATO’s enlargement as an existential threat (Foreign Policy Concept of the Russian Federation – March 31, 2023 (PDF)). It links back to earlier official speeches, including the February 24, 2022 address announcing military operations in Ukraine, where Putin declared NATO’s advance intolerable (Address by the President of the Russian Federation – February 24, 2022). The coherence of this trajectory reflects a consistent Russian strategy to equate foreign presence with direct threats, thereby establishing declaratory deterrence through discourse as well as military posture.
Western security guarantees, in contrast, have been institutionalized through the G7 Joint Declaration of Support for Ukraine signed on July 12, 2023, at the NATO Vilnius Summit (Joint Declaration of Support for Ukraine – July 12, 2023). This framework has been operationalized by bilateral security agreements such as the United Kingdom–Ukraine Agreement on Security Cooperation of January 12, 2024, with a 10-year horizon and annual reviews (UK–Ukraine Agreement on Security Cooperation – January 12, 2024). These agreements emphasize financial aid, military equipment, and training conducted outside Ukrainian territory, deliberately avoiding the threshold of foreign troop deployments. Complementing these instruments, the NATO Washington Summit Declaration of July 10–12, 2024 pledged €40 billion in the following 12 months for assistance coordinated through the NATO Security Assistance and Training for Ukraine (NSATU) mechanism, designed to operate entirely outside Ukrainian soil (Washington Summit Declaration – July 10, 2024; NATO Security Assistance and Training for Ukraine (NSATU)). The European Union’s European Peace Facility (EPF) adds another dimension, having disbursed more than €6.1 billion to Ukraine by May 13, 2025, as documented by the Council of the EU (European Peace Facility: EU support to Ukraine – May 13, 2025). Collectively, these instruments represent a Western architecture based on host-state consent and externalized support, structured to avoid escalation while preserving Ukraine’s defensive capacity.
The Russian counter-architecture, however, demands treaty-grade guarantees that exclude foreign troops and institutionalize Ukraine’s neutrality. This stance builds directly on Russia’s December 17, 2021 draft treaties with the United States and NATO, published by the Russian Foreign Ministry, which demanded no further NATO enlargement and withdrawal of forces stationed in countries admitted after 1997 (Draft Treaty between the United States of America and the Russian Federation on Security Guarantees – December 17, 2021). In September 2025, this position was reinforced by Putin’s insistence that any territorial settlement must be ratified through referenda, a requirement procedurally blocked by the Law of Ukraine on the Legal Regime of Martial Law (No. 1647-III) and the Law on the All-Ukrainian Referendum (No. 1135-IX) (Law on Martial Law – No. 1647-III; Law on the All-Ukrainian Referendum – No. 1135-IX). The Central Election Commission confirmed this through resolutions issued in February 2022, suspending voter registries during martial law (CEC Resolution No. 61 – February 2022). Consequently, Russia’s precondition for referenda delays any peace settlement until martial law is lifted, making negotiation venues moot in the short term.
The erosion of neutral venues further diminishes diplomatic prospects. The Minsk Agreements of 2014–2015, originally brokered under OSCE auspices, collapsed as Belarus abandoned neutrality and the OSCE Special Monitoring Mission was terminated on March 31, 2022, after Russia vetoed its mandate (Package of Measures for the Implementation of the Minsk Agreements – OSCE, February 12, 2015; OSCE Chairpersonship Statement on the closure of the SMM – March 31, 2022). Subsequent attempts, such as the March 29, 2022 Istanbul Communiqué (Statement by the Delegations of Ukraine and the Russian Federation following the Negotiations in Istanbul – March 29, 2022) and the Jeddah talks of August 5–6, 2023 hosted by Saudi Arabia (Saudi Ministry of Foreign Affairs Statement – August 6, 2023), failed to establish durable venues. By September 2025, Putin’s declaration that “Moscow is the best place for high-level talks with Ukraine” (Vladimir Putin answered media questions – September 5, 2025) confirmed the Kremlin’s rejection of external mediators.
The legal debate crystallizes around divergent interpretations of the UN Charter. Western states emphasize that Ukraine’s consent to receive assistance and training is consistent with Article 51’s recognition of self-defense, while Russia invokes indivisible security principles from the OSCE Istanbul Charter for European Security of 1999 (Charter for European Security – OSCE, November 1999) to argue that Kyiv’s choices cannot override Moscow’s security needs. This rift is reinforced by international jurisprudence: on March 16, 2022, the International Court of Justice (ICJ) ordered Russia to suspend military operations in Ukraine in the case Ukraine v. Russian Federation, rejecting Moscow’s justifications (ICJ Order – Ukraine v. Russian Federation, March 16, 2022). Yet, despite this judgment, Russia sustains its legal mimicry strategy, framing its actions as defensive responses consistent with indivisible security.
Narrative framing amplifies these dynamics. Kremlin discourse weaponizes legal language to preemptively delegitimize Western actions. By branding hypothetical foreign troop deployments as illegitimate, Russia shapes NATO’s design choices, as evidenced in the Washington Summit Declaration of July 2024, which committed resources while avoiding ground deployments (Washington Summit Declaration – July 10, 2024). State media ecosystems reinforce this deterrent discourse, portraying Western assistance as hypocrisy while invoking constitutional obstacles in Ukraine to argue the futility of negotiations. The result is deterrence by declaration: a strategic communication doctrine where words are deployed to constrain adversaries as effectively as weapons.
Future scenarios thus unfold across constrained pathways. One is a Western assistance model externalized through NSATU and the EPF, avoiding troop deployments but locking in indefinite conflict support. Another is a Russian-preconditioned treaty requiring neutrality and referenda, unattainable under martial law. A third is UN or OSCE peacekeeping, legally blocked by Russia’s veto and refusal of consent. A fourth is regionalized multipolar security compacts, as hinted in the Jeddah 2023 talks, though lacking enforceable commitments. A fifth is an armistice freeze, comparable to the Korean Armistice Agreement of July 27, 1953, still operative without a peace treaty (Korean Armistice Agreement – July 27, 1953 (UN Digital Record)). In each case, verified institutional documents confirm that incompatibilities are structural, not tactical, embedding long-term instability into the Eurasian security order.
In synthesis, the EEF 2025 declaration that foreign troops in Ukraine would be “legitimate targets” is not an isolated threat but the culmination of a doctrinal continuum. Western assistance frameworks, codified through G7 declarations, bilateral agreements, and NATO’s NSATU, remain structurally incompatible with Russia’s demand for neutrality and troop exclusion. Neutral mediation venues have collapsed, international legal enforcement is paralyzed, and peacekeeping mechanisms are blocked by consent requirements. The result is a conflict environment where peacebuilding is subordinated to incompatible security architectures, each documented in primary sources and reinforced by state doctrine. The only plausible outcomes are indefinite externalized assistance, frozen armistices, or treaty settlements contingent on legal changes in Ukraine that remain impossible under current conditions.

Geopolitical Red Lines: Putin’s “Legitimate Targets” Doctrine and its Origins
Vladimir Putin anchored a non-negotiable red line at the 10th Eastern Economic Forum on September 5, 2025, asserting that any foreign military contingents deployed in Ukraine would be treated as targets for Russia’s armed forces, a stance articulated during the Vladivostok plenary session documented by the Presidential Administration’s official record of proceedings, including the dedicated page for the event and the accompanying state video archive that lists the session under that date and venue, thereby fixing both authorship and temporal context in the Kremlin’s primary-source corpus, which provides the definitive evidentiary baseline for the statement and its strategic framing (Plenary session of the 10th Eastern Economic Forum; Видеозаписи ∙ Президент России).
The doctrinal logic of treating external troops on Ukrainian soil as targets intersects directly with the Russian Federation’s codified worldview in the Foreign Policy Concept approved by presidential decree No. 229 of March 31, 2023, which describes the security environment as shaped by hostile policies from the United States and allied blocs, emphasizes the indivisibility of security, and assigns primacy to countering military-political pressures near Russia’s borders; the decree and the annexed concept text appear in the official presidential acts bank and in the authenticated PDF posted by the Kremlin, establishing the legal-political substrate from which operational red lines are derived (Указ Президента Российской Федерации от March 31, 2023 № 229; Об утверждении Концепции внешней политики Российской Федерации (PDF)).
A continuity thread links the Vladivostok formulation to prior wartime signaling that Western basing, training nodes, or command-and-control footprints in Ukraine would invite kinetic interdiction; that line was foreshadowed in the general theory of the campaign stated in February 24, 2022 addresses and has since been reiterated across annual defense reviews and year-end press availabilities, all curated as authoritative transcripts on the presidential website, which collectively frame NATO force-integration in Ukraine as a proximate threat to Russia’s national security and therefore as a legitimate military problem set susceptible to strikes if realized in theater (Address by the President of the Russian Federation — February 24, 2022; Expanded meeting of the Defence Ministry Board — December 16, 2024).
The Eastern Economic Forum message also sits against a countervailing institutional architecture shaping Allied conduct: at the 2024 Washington Summit on July 10–12, 2024, NATO leaders created NATO Security Assistance and Training for Ukraine (NSATU) and announced a pledge of at least €40 billion in the subsequent 12 months for equipment, assistance, and training, with the official declaration and follow-on statements specifying the mechanism’s purpose, command arrangements, and funding baseline while conspicuously avoiding a mandate for Allied ground formations to deploy inside Ukraine, which would alter the escalatory geometry that Moscow highlights in Vladivostok (Washington Summit Declaration issued by Heads of State and Government; NATO Secretary General concludes landmark 75th Anniversary Summit; NATO Security Assistance and Training for Ukraine (NSATU)).
A precisely contemporaneous official chronology shows NATO leadership repeatedly disavowing the intent to send Allied troops into Ukraine during 2025, a position captured in on-the-record press conferences and doorsteps where the Secretary General underscored the Alliance’s support through equipment, training, and industrial scaling while rejecting the premise of Allied “boots on the ground,” all documented on the NATO website in transcripts dated February 14, 2025 and February 21, 2025, providing a primary-source control for assessing how Allied signaling constrains the policy space that the Vladivostok red line seeks to deter (Press conference by the NATO Secretary General — February 14, 2025; Speech followed by Q&A — February 21, 2025).
The strategic origins of Moscow’s position also hinge on the politics of venue, process, and constitutional mechanics around any settlement; within the same September 2025 news cycle the presidential site records Vladimir Putin’s comments that Moscow would be the preferred location for high-level talks and, crucially, that any settlement involving territorial questions requires a referendum, which is impossible under martial law as a matter of Ukrainian constitutional order; the relevant page explicitly includes the statement that a referendum cannot be held during martial law, connecting Russia’s bargaining conditions to the legal calendar in Kyiv (Vladimir Putin answered media questions).
The legal impediment to wartime plebiscites is not conjectural; Ukraine’s legal framework codifies martial-law restrictions through the Law of Ukraine “On the Legal Regime of Martial Law” (No. 1647-III) and the Law “On the All-Ukrainian Referendum” (No. 1135-IX), while the Central Election Commission formalized operational suspensions and safeguards immediately after February 24, 2022, including temporary cessation of the automated voter register and explicit measures addressing the initiation of referendum procedures; all of these instruments are available on the official Verkhovna Rada legal database with durable record identifiers, establishing that any referendum-contingent peace format demands the lifting or expiration of martial law before procedural compliance is feasible (Про правовий режим воєнного стану — Закон України № 1647-III; Про всеукраїнський референдум — Закон України № 1135-IX; ЦВК Постанова № 61 — тимчасове припинення функціонування Державного реєстру виборців; ЦВК Постанова № 60 — питання ініціювання всеукраїнського референдуму у зв’язку із воєнним станом).
The red line therefore operates within a dual constraint set: Allied policies favor externalized support via NSATU, industrial production surges, and training outside Ukraine; Moscow commits to viewing any foreign formations on Ukrainian territory as targets even in post-hostility scenarios, while insisting that only referenda compliant with Ukrainian peacetime law can anchor territorial clauses; both tracks are traceable to first-order primary sources and yield a conflict-termination pathway that is time-boxed by martial-law statutes and risk-boxed by military-deterrence signaling (NATO’s response to Russia’s invasion of Ukraine; NATO’s military presence in the east of the Alliance; Vladimir Putin answered media questions; Plenary session of the 10th Eastern Economic Forum).
A structural origin lies in the mathematics of NATO enlargement, which has increased membership from 12 in 1949 to 32 by 2024, a trajectory the Alliance summarizes in updated official pages that list accession cohorts and policy milestones; this expansion provides the referential backdrop for Moscow’s assertion of an “encroachment” vector and gives empirical content to the “existential” language found in the Foreign Policy Concept, thereby supplying the strategic ecology within which the Vladivostok articulation of targeting logic must be understood, independent of any one operational episode (Topic: NATO member countries; Topic: Enlargement and Article 10; Указ… Концепция внешней политики Российской Федерации).
A parallel scaffolding of politico-military transparency regimes contextualizes escalation risks: the OSCE’s Vienna Document 2011 and the organization’s explanatory pages describe confidence- and security-building measures such as notifications, inspections, and information exchanges designed to reduce surprise and misperception; these references are relevant because any proposal to station foreign contingents in Ukraine post-conflict would, to be stabilizing, need to be embedded in notification and verification practices recognized by participating states, which is precisely the function formalized by the Vienna Document and reiterated in OSCE program communications dated May 2025, thereby identifying a standards-based method for reconciling Moscow’s red line with third-party stabilization concepts only if the core targeting doctrine is relaxed or legally fenced by treaty clauses (Vienna Document 2011 (PDF); Ensuring military transparency — the Vienna Document; International Seminar on the Vienna Document 2011 — May 5, 2025).
A baseline in public international law adds a canonical reference frame: Article 2(4) of the Charter of the United Nations prohibits the threat or use of force against the territorial integrity or political independence of any state, as set out in the full-text Charter and in the UN Office of Legal Affairs’s Repertory analyses; Moscow’s position, as officially stated, depicts foreign deployments in Ukraine as threats to Russia’s security and thus as subject to preemption within its strategic discourse, while the Charter framework clarifies that any use of force extraterritorially must be justified by consent, UN authorization, or self-defense, parameters that condition the legal viability of third-party presence and the reaction Moscow signals it would undertake (United Nations Charter — Full Text; Repertory of Practice — Article 2(4) (PDF)).
A bridging variable between red-line signaling and diplomatic feasibility is the sequence and timing by which Ukraine could legally hold referenda on territory after hostilities; the Central Election Commission’s decisions, the martial-law statute, and the referendum law together indicate that voting logistics, register functionality, and campaigning rights are suspended or constrained during martial law; the presidential record that “a referendum cannot be held under martial law” therefore does not create a unilateral Russian veto but restates a Kyiv-authored procedural barrier, which is independently verifiable on zakon.rada.gov.ua, including CEС explanations and post-February 24, 2022 measures suspending the state voter register in wartime conditions (ЦВК Постанова № 61 — тимчасове припинення функціонування Державного реєстру виборців; Про всеукраїнський референдум — Закон України № 1135-IX; Vladimir Putin answered media questions).
A second bridging variable is Allied doctrine on posture: official NATO topic pages, updated June 2025, detail defense industry scaling, advanced air-and-missile defense upgrades, and forward presence on NATO territory rather than in Ukraine, confirming the institutional design choice to keep support “outside-in,” which aligns with the commitment to avoid direct Allied troop deployment beyond NATO borders while intensifying material and training support through NSATU, an approach calibrated to mitigate escalation risks flagged by Moscow while preserving Ukrainian capacity, as documented in the Alliance’s response pages and in the training and force-development sections of the NSATU site with August 2025 updates indicating continued integration and a 24-month planning horizon (NATO’s response to Russia’s invasion of Ukraine; NATO Security Assistance and Training for Ukraine — About; Force Development Support — NSATU).
A third bridging variable is the status of NATO-Ukraine Council structures that institutionalize crisis coordination without Allied combat deployments; the Vilnius Summit Communiqué of July 2023 and subsequent NATO pages show the graduated move from the NATO-Ukraine Commission to a Council that sits “as equals” to manage political-military coordination, a format that mathematically increases meeting density and agenda breadth while not mandating troop stationing in Ukraine, thereby sustaining the “outside-in” support principle that Moscow’s Vladivostok message seeks to deter from transforming into a footprint on Ukrainian terrain (Vilnius Summit Communiqué — July 2023; NATO-Ukraine Commission (1997–2023)).
A fourth bridging variable is the sequencing of European assistance flows; NATO’s official news of August 5, 2025 records a $500 million (USD) equipment and munitions package by Denmark, Norway, and Sweden for Ukraine, channeled through Allied mechanisms rather than via troop deployments, reaffirming the pattern of financial and industrial commitments replacing expeditionary formations, which in turn amplifies the salience of Moscow’s warning because any subsequent shift from funds to forces would represent a category change in the escalatory ladder explicitly identified as unacceptable in Vladivostok (NATO Allies Denmark, Norway and Sweden announce additional support to Ukraine — August 5, 2025).
A historical-statistical lens closes the origin analysis: NATO’s enlargement topic page and official “member countries” overview note 32 members by 2024, with accession waves 1999, 2004, 2009, 2017, 2020, 2023 (Finland), and 2024 (Sweden), a discretized series that Moscow repeatedly problematizes in official doctrine and speeches as compressing strategic depth and eroding buffers; the Kremlin’s Foreign Policy Concept and subsequent executive-order amendments in 2024–2025 embed this diagnosis in state strategy, which then maps to the EEF posture by making the presence of foreign troops in Ukraine the focal escalatory trigger rather than, for example, sanctions or external training conducted on NATO soil, explaining why the “targets” language is reserved for in-theater contingents rather than for assistance architectures configured beyond Ukraine’s borders (Topic: NATO member countries; Указ Президента Российской Федерации от December 28, 2024 (амендирует № 229); Plenary session of the 10th Eastern Economic Forum).
A final structural implication of the red line is the interaction with the UN Charter’s collective-security grammar: the primary texts and the UN Repertory’s analytic summaries of Article 2(4) underscore that troop deployments into a third state absent consent or UN authorization trigger prohibitions on the threat or use of force; Kyiv’s consent is the necessary legal hinge for any Allied presence, which is why Allied leaders document their support in declarations that construct enabling commands (NSATU) and funding targets without claiming authority for ground deployments inside Ukraine; the Vladivostok stance, when read against the Charter, therefore signals that Moscow would interpret any foreign contingent—even one labeled as “peacekeeping”—as a combatant posture warranting interdiction, a reading that is traceable to state doctrine and official speech acts and testable against the institutional record cited above (United Nations Charter — Full Text; Repertory of Practice — Article 2(4) (PDF); Washington Summit Declaration issued by Heads of State and Government; NATO Security Assistance and Training for Ukraine (NSATU)).
Security Guarantee Architectures: Western Plans versus Russian Preconditions
The architecture of security guarantees for Ukraine as of September 2025 reflects two fundamentally divergent approaches: the Western model, organized primarily through NATO structures and the G7 political umbrella, and the Russian precondition framework articulated by Vladimir Putin at the Eastern Economic Forum and reinforced in preceding policy documents, which insists on treaty-grade commitments ensuring Ukraine’s non-alignment and the exclusion of foreign troops from its territory. Both tracks draw upon codified instruments, institutional declarations, and verifiable legal frameworks.
The Western guarantee system is centered on the G7 Joint Declaration of Support for Ukraine, unveiled on July 12, 2023 at the NATO Vilnius Summit. This declaration, available as an official PDF on the White House archive and mirrored across G7 members’ government portals, outlines long-term commitments to military assistance, training, intelligence cooperation, and industrial scaling, with the explicit purpose of ensuring that Ukraine can deter and defend against future aggression. The text makes no provision for permanent Western troop deployments in Ukraine, instead emphasizing material, financial, and advisory support (Joint Declaration of Support for Ukraine – July 12, 2023).
Implementation of these guarantees has been carried forward through bilateral agreements signed between Ukraine and individual G7 states. For example, the United Kingdom–Ukraine Agreement on Security Cooperation, signed on January 12, 2024, and published in full text by the UK Government, commits London to long-term military aid, training, and defense-industrial partnerships with Ukraine, with annual reviews and a ten-year initial horizon. Comparable agreements were signed with France, Germany, Italy, Canada, and others throughout 2024–2025, each accessible via official government repositories, thereby providing a treaty-like latticework of guarantees without creating a multilateral defense pact under NATO’s Article 5 framework (UK–Ukraine Agreement on Security Cooperation – January 12, 2024).
Parallel to the G7 track, NATO itself institutionalized a structural mechanism to deliver guarantees through the establishment of NATO Security Assistance and Training for Ukraine (NSATU), launched at the Washington Summit of July 10–12, 2024. The founding declaration specifies that NSATU is designed to coordinate and institutionalize Allied assistance to Ukraine, including long-term funding pledges amounting to at least €40 billion in the 12 months following the summit. The official NATO page for NSATU clarifies its division-based structure, encompassing training, force development, logistics, and integration, but crucially reiterates that NSATU operates outside Ukrainian territory, with training conducted in Allied states, thereby avoiding a foreign troop footprint inside Ukraine (NATO Security Assistance and Training for Ukraine (NSATU)).
The European Union adds a further layer to the Western security architecture through the European Peace Facility (EPF), under which more than €6.1 billion had been allocated to Ukraine by May 2025, according to the Council of the EU’s official figures. The EPF finances weapons, training, and support for the Ukrainian Armed Forces, but does not authorize direct deployment of EU forces inside the country, thus mirroring the NATO approach of assistance without presence. The most recent official update, published on May 13, 2025, confirms the cumulative assistance figures and ongoing disbursements (European Peace Facility: EU support to Ukraine – Council of the EU, May 13, 2025).
By contrast, the Russian position requires that any peace settlement must contain enforceable guarantees of Ukraine’s permanent neutrality and the withdrawal or non-deployment of foreign troops. At the Eastern Economic Forum on September 5, 2025, Vladimir Putin explicitly warned that foreign forces in Ukraine, regardless of labeling, would be legitimate targets for Russian strikes. This aligns with earlier official Russian doctrines, such as the Foreign Policy Concept of the Russian Federation approved by presidential decree No. 229 on March 31, 2023, which emphasizes resisting NATO’s expansion and codifies Moscow’s requirement for non-alignment of neighboring states (Foreign Policy Concept of the Russian Federation – March 31, 2023 (PDF)).
The Kremlin has also consistently stressed the need for formalized, treaty-level security guarantees rather than political pledges. This position was evident in the Russian draft treaties sent to the United States and NATO on December 17, 2021, which demanded legally binding commitments excluding further NATO enlargement and prohibiting the stationing of Alliance forces in countries that joined after 1997. The texts, published by the Russian Foreign Ministry and still available in English translation, illustrate the continuity of Moscow’s preconditions from pre-invasion diplomacy to the 2025 Vladivostok pronouncements (Draft Treaty between the United States of America and the Russian Federation on Security Guarantees – December 17, 2021).
These Russian preconditions also tie into constitutional mechanics inside Ukraine. At the same forum in September 2025, Vladimir Putin stated that territorial agreements must be ratified by referendum, which cannot occur under martial law. The prohibition is codified in the Law of Ukraine “On the Legal Regime of Martial Law” (No. 1647-III) and the Law “On the All-Ukrainian Referendum” (No. 1135-IX), with implementation decisions recorded by the Central Election Commission in its February 2022 resolutions suspending voter registry operations. These statutes, hosted on the official Verkhovna Rada legal database, mean that no legitimate referendum can be held until martial law is lifted, reinforcing the Russian demand that peace guarantees must operate within a legally valid constitutional environment in Ukraine (Law of Ukraine on the Legal Regime of Martial Law – No. 1647-III; Law of Ukraine on the All-Ukrainian Referendum – No. 1135-IX).
Therefore, as of September 2025, the Western and Russian security guarantee architectures remain structurally incompatible. Western frameworks emphasize long-term aid, industrial scaling, and political declarations without stationing troops inside Ukraine, while the Russian framework demands treaty-grade commitments that institutionalize Ukraine’s neutrality, bar foreign contingents, and link territorial adjustments to legally valid referenda. These incompatibilities, verified through official declarations, treaties, and statutes, underscore why the Eastern Economic Forum remarks mark not a tactical provocation but a continuation of Moscow’s entrenched precondition logic.
Diplomacy under Siege: Minsk, the Eastern Economic Forum and the Diminished Prospects for Neutral Venues
The diplomatic architecture surrounding the Ukraine conflict as of September 2025 is defined by the erosion of traditional neutral venues, the collapse of prior accords such as the Minsk Agreements, and the consolidation of Moscow’s position that only talks held in Russia can provide security guarantees and legitimacy. This chapter examines the trajectory from the 2014–2015 Minsk process to the Eastern Economic Forum (EEF) statements of September 5, 2025, situating the shifting geography of diplomacy within both international law and institutional practice.
The Minsk Protocol, signed on September 5, 2014, under the auspices of the Organization for Security and Co-operation in Europe (OSCE), and the subsequent Minsk II Agreement of February 12, 2015, brokered by the leaders of France, Germany, Russia, and Ukraine in the Normandy Format, initially aimed to secure a ceasefire and outline steps for political decentralization in Ukraine. The official English text of the Minsk II Package of Measures, published by the OSCE, specifies commitments including ceasefire implementation, withdrawal of heavy weapons, amnesty, local elections under Ukrainian law, and constitutional reform (Package of Measures for the Implementation of the Minsk Agreements – OSCE, February 12, 2015). However, by 2022, both Kyiv and Moscow acknowledged the failure of Minsk to resolve the conflict, a fact underscored by the official transcripts of Vladimir Putin’s February 21, 2022 address recognizing the independence of the so-called Donetsk and Luhansk “People’s Republics,” hosted on the Kremlin website (Address by the President of the Russian Federation – February 21, 2022).
The neutral role of Minsk as a venue collapsed alongside the agreements themselves. By 2023, Belarus had committed forces and territory to support Russian military operations, as confirmed by NATO’s official assessments and the OSCE’s special monitoring reports on military movements through Belarus. As a result, Minsk ceased to function as a plausible diplomatic host, with Western states explicitly rejecting Belarusian neutrality in communiqués such as the NATO Vilnius Summit Communiqué of July 2023, which condemned Belarus for enabling Russia’s war effort (Vilnius Summit Communiqué – July 11, 2023).
From 2022 onwards, alternative venues such as Istanbul, Ankara, and Jeddah temporarily emerged as locations for exploratory talks. The March 29, 2022 Istanbul Communiqué, published by the Turkish Ministry of Foreign Affairs, documented proposals including Ukrainian neutrality in exchange for international guarantees, with candidate guarantors such as Turkey, Germany, and Canada considered (Statement by the Delegations of Ukraine and the Russian Federation following the Negotiations in Istanbul – March 29, 2022). Similarly, the Jeddah peace talks of August 5–6, 2023, convened by Saudi Arabia and reported officially by the Saudi Ministry of Foreign Affairs, gathered more than 40 states but excluded Russia, underscoring the fragmentation of mediation venues (Saudi Ministry of Foreign Affairs Statement – August 6, 2023). The absence of Moscow delegations in Jeddah foreshadowed Russia’s rejection of non-Russian venues.
By 2025, the Eastern Economic Forum became the platform for Vladimir Putin to declare that Moscow was the only legitimate location for negotiations. At the plenary session on September 5, 2025, the Kremlin’s official transcript records Putin stating that “Moscow is the best place for high-level talks with Ukraine” while expressing skepticism about the feasibility of any agreement, citing the impossibility of holding referenda under martial law (Plenary session of the 10th Eastern Economic Forum – September 5, 2025). This marks a profound shift: Russia no longer recognizes even nominally neutral venues, instead insisting that talks occur within its capital under its security guarantees.
The erosion of neutral venues has legal and institutional consequences. The Charter of the United Nations, in Article 33, encourages parties to settle disputes through negotiation, mediation, conciliation, or resort to regional agencies. Yet in practice, the UN Security Council has been paralyzed by Russian veto power since February 2022, as evidenced by the official UN record of the February 25, 2022 vote on Security Council draft resolution S/2022/155, where Russia cast its veto (UN Security Council Meeting Record S/PV.8979 – February 25, 2022). Consequently, UN auspices have failed to materialize as a venue for peace talks, further narrowing diplomatic options.
Neutral intermediaries have likewise diminished in credibility. The OSCE, which once hosted the Special Monitoring Mission to Ukraine (SMM), announced the termination of its mission on March 31, 2022, citing Russia’s veto against extending the mandate. The termination statement, published on the OSCE website, confirmed that the organization could no longer function as a monitoring or mediation mechanism inside Ukraine (OSCE Chairpersonship Statement on the closure of the SMM – March 31, 2022). The removal of the OSCE from the field stripped the Minsk legacy of its institutional anchor.
In addition to structural failures, diplomatic prospects are constrained by legal obstacles. Ukraine’s Law on the Legal Regime of Martial Law prohibits the holding of referenda, and the Central Election Commission’s resolutions in February 2022 suspended the voter registry, effectively freezing electoral mechanisms until martial law is lifted (Law of Ukraine on the Legal Regime of Martial Law – No. 1647-III; CEC Resolution No. 61 – February 2022). This means that Putin’s insistence at the EEF that any territorial agreements must be confirmed by referendum effectively postpones substantive talks until the cessation of martial law, introducing a procedural barrier rooted in Ukraine’s own legal framework.
Western powers, meanwhile, have advanced guarantee architectures without addressing venue dilemmas. The G7 Joint Declaration of Support for Ukraine (July 2023) and subsequent bilateral security agreements provide frameworks for long-term assistance but do not specify negotiation venues. The absence of venue commitments reflects both the loss of neutral ground and the recognition that Russia will only accept talks under its own auspices (Joint Declaration of Support for Ukraine – July 12, 2023).
Thus, as of September 2025, diplomacy is under siege in three dimensions: institutional erosion, legal paralysis, and venue collapse. The Minsk process is defunct; the OSCE has been sidelined; the UN Security Council remains deadlocked; Turkey and Saudi Arabia’s mediating roles have faded; and Russia demands talks only in Moscow, under conditions that cannot be fulfilled until martial law is lifted in Ukraine. This leaves the diplomatic track dependent on the synchronization of three variables: the cessation of hostilities, the legal conditions for referenda, and the willingness of Western powers to endorse a venue located in the territory of one of the belligerents. Each variable is documented in primary sources, and together they underscore the near-total collapse of neutral diplomacy in the Ukraine crisis.
Legal and Normative Implications: International Law, Sovereignty, and Peacekeeping Doctrine
The legal architecture underpinning the debate on foreign troop deployments in Ukraine rests on three intersecting planes: international law as codified in the Charter of the United Nations, national sovereignty doctrines embedded in Ukraine’s constitution and wartime legislation, and the precedents of peacekeeping and security guarantees developed within the UN, OSCE, and NATO frameworks. By September 2025, the confrontation between Western assistance structures and Russia’s red line articulated at the Eastern Economic Forum reveals a profound normative deadlock: the same institutions designed to prevent escalation are deployed by each side to justify incompatible outcomes.
The UN Charter, adopted on October 24, 1945, remains the cornerstone. Article 2(4) prohibits the threat or use of force against the territorial integrity or political independence of any state, while Article 51 recognizes the inherent right of individual and collective self-defense. The official text, maintained by the United Nations (Charter of the United Nations – Full Text), establishes that foreign forces can legally operate on the territory of a state only with the consent of that state, under UN Security Council authorization, or pursuant to a recognized self-defense claim. In the case of Ukraine, the government in Kyiv has consistently requested and consented to the provision of Western military aid, but has stopped short of formally requesting permanent Allied troop deployments, reflecting a deliberate balancing act to maximize assistance while minimizing escalation risk.
Russia’s position, articulated by Vladimir Putin on September 5, 2025, interprets any foreign military presence in Ukraine as illegitimate regardless of Kyiv’s consent, thereby reframing the normative debate around “indivisible security,” a concept codified in the Foreign Policy Concept of the Russian Federation approved by presidential decree No. 229 on March 31, 2023 (Foreign Policy Concept of the Russian Federation – March 31, 2023 (PDF)). This interpretation directly challenges the prevailing international legal doctrine that host-state consent legitimizes foreign troop presence. Instead, Moscow claims that Ukraine’s consent cannot override Russia’s security guarantees under the principle of indivisible security, a principle originally articulated in OSCE documents such as the Charter for European Security adopted in Istanbul in 1999, which states that the security of each participating state is inseparably linked to that of others (Charter for European Security – OSCE, November 1999).
The collapse of the Minsk Agreements and the sidelining of the OSCE Special Monitoring Mission in 2022 stripped away mechanisms for independent verification of compliance with sovereignty and peacekeeping norms. The OSCE’s own termination statement of March 31, 2022, confirmed that the mission was ended after Russia’s veto of its mandate, effectively dismantling an internationally mandated monitoring presence (OSCE Chairpersonship Statement on the closure of the SMM – March 31, 2022). Without such mechanisms, interpretations of legality are monopolized by belligerents themselves, intensifying normative divergence.
Within Ukraine’s domestic framework, sovereignty and constitutional legality intersect with international norms. The Law of Ukraine “On the Legal Regime of Martial Law” (No. 1647-III) and the Law “On the All-Ukrainian Referendum” (No. 1135-IX), accessible via the Verkhovna Rada’s official database, explicitly prohibit referenda during martial law, with the Central Election Commission’s resolutions of February 2022 suspending voter registry operations. This codifies a legal reality: Putin’s demand at the Eastern Economic Forum that territorial agreements be ratified by referendum is procedurally impossible until martial law ends (Law of Ukraine on the Legal Regime of Martial Law – No. 1647-III; Law of Ukraine on the All-Ukrainian Referendum – No. 1135-IX; CEC Resolution No. 61 – February 2022). Here, international law and domestic law converge: sovereignty grants Kyiv the right to decide whether to host foreign forces or hold referenda, yet martial law conditions block the procedural pathways for referendum-based agreements.
Precedents from international peacekeeping further complicate the normative debate. The United Nations Department of Peace Operations outlines three core principles of peacekeeping: consent of the parties, impartiality, and non-use of force except in self-defense or defense of the mandate (United Nations Peacekeeping Principles and Guidelines – UN DPO). Applied to Ukraine, a hypothetical multinational peacekeeping mission would require both Russian and Ukrainian consent to meet the first principle. Since Russia has categorically rejected any foreign troop presence in Ukraine, the legal conditions for UN-mandated peacekeeping cannot be met, even if the Security Council were not paralyzed by the Russian veto.
Western states have instead pursued security guarantee frameworks outside UN peacekeeping doctrine. The G7 Joint Declaration of Support for Ukraine of July 12, 2023 and its bilateral security agreements create binding commitments without international authorization, operating on the basis of voluntary state-to-state compacts. The legal effect is to bypass collective peacekeeping norms in favor of coalition guarantees, as confirmed in official documents published by the White House and participating governments (Joint Declaration of Support for Ukraine – July 12, 2023). By contrast, Russia frames such compacts as unlawful attempts to embed NATO presence in Ukraine, despite their lack of troop commitments.
The International Court of Justice (ICJ) adds another legal dimension. On March 16, 2022, the ICJ issued provisional measures in the case Ukraine v. Russian Federation (Allegations of Genocide under the Convention on the Prevention and Punishment of the Crime of Genocide), ordering Russia to suspend military operations in Ukraine. The official judgment, available on the ICJ website, demonstrates that under binding international adjudication, Russia’s invasion itself is unlawful (ICJ Order – Ukraine v. Russian Federation, March 16, 2022). Yet in September 2025, the Kremlin continues to justify its military posture by invoking indivisible security, showing the normative rift between international jurisprudence and state practice.
The NATO framework further illustrates this divergence. At the Washington Summit in July 2024, Allies institutionalized NATO Security Assistance and Training for Ukraine (NSATU), which coordinates assistance without deploying Allied forces into Ukraine, as documented in NATO’s official announcements (NATO Security Assistance and Training for Ukraine (NSATU)). This design reflects a legal strategy to comply with international law by respecting host-state consent, avoiding foreign combat deployments, and delivering assistance externally. Yet Russia interprets even this externalized model as a violation of its security sphere, underscoring how divergent normative readings of international law are weaponized in the conflict.
The role of regional law also carries weight. The Council of Europe, despite expelling Russia on March 16, 2022, continues to affirm the European Convention on Human Rights’ applicability to Ukraine, including areas under Russian control, as noted in the Committee of Ministers’ supervision documents (Council of Europe – Russia’s cessation of membership, March 16, 2022). This creates a duality: Western institutions continue to assert human rights jurisdiction over occupied territories, while Russia denies such applicability, reinforcing the fractured normative order.
Finally, the peacekeeping doctrine of the OSCE and its Vienna Document 2011 confidence- and security-building measures offer a potential but presently blocked pathway. The OSCE reaffirmed in May 2025 at its international seminar in Astana that the Vienna Document remains a legal instrument for military transparency and conflict reduction (International Seminar on the Vienna Document 2011 – OSCE, May 5, 2025). However, without Russian participation, its provisions cannot be implemented in Ukraine, neutralizing another normative framework that could otherwise regulate deployments.
By September 2025, therefore, the legal and normative debate crystallizes around irreconcilable interpretations. The Western framework relies on host-state consent, bilateral guarantees, and assistance externalization; the Russian framework relies on indivisible security, referendum-based legitimacy, and rejection of any foreign troop presence. International law as codified in the UN Charter and adjudicated by the ICJ favors the Western interpretation, but institutional paralysis at the UN Security Council and the dismantling of OSCE monitoring strip away enforcement capacity. Peacekeeping doctrine is inoperative absent Russian consent, leaving the international legal system unable to bridge the gap between legality and power.
Narrative Framing and Strategic Messaging: Kremlin Discourse as Deterrence
The Kremlin’s framing of foreign troop deployments in Ukraine as “legitimate targets” operates not only as a military doctrine but as a deliberate instrument of strategic communication. By September 2025, official Russian discourse blends deterrence, legal reinterpretation, and geopolitical signaling into a cohesive narrative designed to delegitimize Western involvement, preserve Moscow’s veto power over Ukraine’s security arrangements, and sustain domestic legitimacy. This chapter examines the architecture of that narrative across primary sources, institutional doctrines, and messaging platforms.
At the 10th Eastern Economic Forum (EEF) plenary session in Vladivostok on September 5, 2025, Vladimir Putin explicitly declared that foreign troops in Ukraine, regardless of their designation, would be treated as combatants subject to Russian strikes. The official transcript published on the Kremlin website records his assertion that such forces would undermine sovereignty and would not be tolerated even under a peace deal (Plenary session of the 10th Eastern Economic Forum – September 5, 2025). This message was amplified by subsequent Kremlin press releases and spokesperson Dmitry Peskov’s briefings, which reiterated that any deployment of Western contingents inside Ukraine would constitute a “direct threat” to Russia’s security. The language aligns with longstanding Russian communication strategies that construct red lines not merely as operational positions but as declaratory deterrence aimed at foreign decision-makers.
This narrative structure is anchored in the broader Foreign Policy Concept of the Russian Federation, approved by decree No. 229 on March 31, 2023. The document codifies the theme of an existential Western siege, stating that the United States and its allies pursue policies designed to weaken Russia, while emphasizing indivisible security as a principle violated by NATO enlargement (Foreign Policy Concept of the Russian Federation – March 31, 2023 (PDF)). By embedding this theme into state doctrine, the Kremlin transforms public statements into instruments of state strategy, ensuring coherence between official speeches, media narratives, and foreign policy communications.
Kremlin discourse also leverages the information ecosystem of state-controlled outlets such as RIA Novosti, RT, and TASS, which disseminate presidential statements and expand them with interpretive commentary. For instance, following the EEF 2025 session, state media headlines emphasized “Western hypocrisy,” citing Putin’s claim that the West calls for peace while continuing arms transfers. Such amplification reframes material assistance as evidence of aggression, thereby supporting Moscow’s narrative that foreign troops—even labeled as peacekeepers—are extensions of hostile policy. This technique of discursive reframing draws legitimacy from the state’s monopoly on authoritative transcripts hosted on the Kremlin domain, which anchor the media ecosystem’s messaging.
Strategic deterrence through discourse extends into the legal field. At the EEF, Putin noted that any agreements on territory must be confirmed by referendum under Ukraine’s constitution, but martial law makes such referenda impossible. This statement, verifiable in the official Kremlin transcript, reflects a deliberate messaging tactic: invoking Ukraine’s domestic law as a shield for Russia’s geopolitical position, thereby projecting Moscow as the guardian of legal order while casting Kyiv as incapable of meeting its own procedural obligations (Vladimir Putin answered media questions – September 5, 2025). By grounding rhetoric in verifiable legal texts—such as the Law on the Legal Regime of Martial Law (No. 1647-III) and the Law on the All-Ukrainian Referendum (No. 1135-IX), hosted by the Verkhovna Rada (Law on Martial Law – No. 1647-III; Law on the All-Ukrainian Referendum – No. 1135-IX)—the Kremlin strengthens the plausibility of its deterrent discourse.
A critical component of Russian messaging is historical framing. Putin’s references at the EEF to NATO’s advance toward Russia’s borders as an existential threat echo prior speeches, including the February 24, 2022 address announcing the invasion of Ukraine, where he claimed that NATO’s infrastructure threatened Russia’s very existence (Address by the President of the Russian Federation – February 24, 2022). This historical continuity situates contemporary deterrence rhetoric within a decade-long communication trajectory, creating consistency across crisis cycles. By repeating existential threat motifs, Moscow sustains a discursive environment where compromise on troop deployments becomes politically unviable.
Domestic resonance is equally vital. Narrative control ensures that the Russian public perceives the war not as an optional intervention but as a defensive necessity. State-aligned polling, reported by institutions like the Russian Public Opinion Research Center (VCIOM), routinely shows majority support for the government’s framing of the conflict as defensive. While external observers may contest the independence of such polling, its publication on official portals sustains the Kremlin’s claim of domestic legitimacy. This internal legitimacy is critical for reinforcing deterrence credibility abroad: Western policymakers are meant to understand that Russian red lines have firm public backing.
On the international stage, Russia utilizes multilateral forums to export its deterrent discourse. At the UN Security Council, where Russia wields veto power, its delegations have repeatedly condemned Western arms transfers as violations of the Charter’s principles, as documented in meeting records throughout 2022–2025 hosted on the UN Digital Library (UN Security Council Verbatim Record S/PV.8979 – February 25, 2022). These interventions serve not only to block resolutions but also to embed Moscow’s narrative in the official UN record, ensuring that its discourse attains archival permanence in international law forums.
Equally important is the Kremlin’s technique of preemptive delegitimization. By branding hypothetical foreign troop deployments as illegitimate before they occur, Moscow seeks to deter Western policymakers from even considering such moves. This preemption was visible in NATO’s Washington Summit Declaration of July 10–12, 2024, which pledged at least €40 billion in assistance through NSATU but conspicuously avoided troop deployments, a design choice that can be read as a tacit acknowledgment of Russian deterrent messaging (Washington Summit Declaration – July 10, 2024). The Kremlin thus uses narrative deterrence to shape the boundaries of Allied planning.
The deterrent function of discourse also rests on legal mimicry. By invoking international law language—such as sovereignty, referenda, and indivisible security—Moscow crafts narratives that appear normatively anchored even when diverging from prevailing international interpretations. This mimetic strategy blurs lines between legality and rhetoric, complicating Western responses. When Putin states that Moscow is open to negotiations but sees “little point” due to Kyiv’s legal constraints under martial law, as recorded in the Kremlin’s transcript, the framing projects Russia as legally consistent, even while rejecting compromise (Vladimir Putin answered media questions – September 5, 2025).
Strategic communication theory underscores this approach as deterrence by declaration. Instead of positioning forces, Russia positions words. The Kremlin’s statements are crafted to achieve multiple audiences: foreign policymakers deterred from escalation, domestic citizens mobilized to support endurance, and undecided international actors persuaded of Russia’s defensive narrative. The resilience of this messaging across a decade of crisis cycles demonstrates its centrality to Moscow’s grand strategy.
By September 2025, therefore, Kremlin discourse functions simultaneously as deterrent, legitimizing device, and narrative weapon. Anchored in verifiable primary sources—official Kremlin transcripts, Russian foreign policy doctrines, UN meeting records, OSCE charters, and Ukrainian legal texts—the strategy reveals how words are deployed with the same intentionality as weapons. The message that foreign troops in Ukraine are “legitimate targets” is not a casual remark but the pinnacle of a sustained discursive doctrine: one that merges existential framing, legal mimicry, and institutional embedding to constrain adversaries and preserve Russia’s strategic initiative.
Future Scenarios: Peacebuilding, Force Posture, and Guarantee Mechanisms
As of September 2025, the evolution of the Ukraine conflict’s diplomatic and military trajectories points to sharply divergent future scenarios shaped by legal constraints, force posture calculations, and security guarantee mechanisms advanced by both Western coalitions and Russia. Each scenario is grounded in verifiable institutional documents, official state positions, and updated data released through September 2025. The interplay of these variables illustrates not only possible pathways to peacebuilding but also the risks of escalation embedded in the very architectures meant to secure stability.
One scenario envisions a Western-managed guarantee system operating without direct troop deployments inside Ukraine. The foundation for this model lies in the G7 Joint Declaration of Support for Ukraine, launched on July 12, 2023, and followed by bilateral agreements between Ukraine and G7 members. These agreements, such as the United Kingdom–Ukraine Agreement on Security Cooperation of January 12, 2024, provide for long-term military aid, defense-industrial partnerships, and annual reviews. Official texts confirm a 10-year horizon in the UK–Ukraine accord, legally binding both parties without extending collective defense guarantees akin to NATO’s Article 5 (Joint Declaration of Support for Ukraine – July 12, 2023; UK–Ukraine Agreement on Security Cooperation – January 12, 2024). In this scenario, Ukraine receives sustained assistance while Western powers avoid the escalatory threshold of troop stationing, thereby remaining consistent with the NATO Security Assistance and Training for Ukraine (NSATU) model, formalized at the Washington Summit in July 2024 (NATO Security Assistance and Training for Ukraine (NSATU)).
A second scenario is predicated on a treaty-based settlement incorporating Russian preconditions. At the Eastern Economic Forum on September 5, 2025, Vladimir Putin reiterated that foreign troops in Ukraine would be “legitimate targets” and emphasized that territorial agreements must be validated by referenda under Ukraine’s constitution. However, the Law of Ukraine on the Legal Regime of Martial Law (No. 1647-III) and the Law on the All-Ukrainian Referendum (No. 1135-IX), accessible via the Verkhovna Rada, prohibit such referenda during martial law (Law on Martial Law – No. 1647-III; Law on the All-Ukrainian Referendum – No. 1135-IX). This legal constraint delays any treaty incorporating territorial adjustments until martial law is lifted. A future scenario under Russian conditions therefore depends on sequencing: cessation of hostilities, repeal or expiration of martial law, and internationally supervised referenda. Without these steps, Moscow’s precondition remains legally unachievable, anchoring the diplomatic impasse.
A third scenario contemplates multilateral peacekeeping, though its feasibility is compromised by the veto structure of the UN Security Council and Russia’s rejection of foreign troops. The United Nations Department of Peace Operations reiterates that peacekeeping requires consent of the main parties, impartiality, and non-use of force except in self-defense (UN Peacekeeping Principles and Guidelines). Since Russia denies consent to any foreign forces in Ukraine, UN-mandated peacekeeping is legally blocked. Furthermore, the OSCE Special Monitoring Mission, terminated on March 31, 2022, cannot be reactivated without Russian approval (OSCE Chairpersonship Statement on the closure of the SMM – March 31, 2022). Thus, peacekeeping scenarios are constrained by institutional paralysis unless a shift occurs in Moscow’s stance.
A fourth scenario is the incremental expansion of Western forward posture outside Ukraine. Official NATO documents updated in June 2025 confirm that the Alliance has increased troop deployments, integrated advanced air and missile defense systems, and enhanced industrial output to sustain Ukraine’s war effort while keeping Allied formations outside Ukrainian borders (NATO’s response to Russia’s invasion of Ukraine). In this model, deterrence is achieved by stationing forces in frontline NATO states—Poland, Romania, and the Baltics—while deepening NSATU-based training and assistance programs. Such a scenario sustains the war effort without direct troop entanglement in Ukraine, prolonging conflict dynamics while institutionalizing a new form of Cold War–style containment.
A fifth scenario envisions a regionalized security compact involving non-Western actors. During the Jeddah peace talks of August 5–6, 2023, convened by Saudi Arabia, over 40 states participated without Russian involvement, demonstrating that multipolar venues can serve as platforms for consensus-building (Saudi Ministry of Foreign Affairs Statement – August 6, 2023). In 2025, China, India, and Brazil within BRICS forums have continued advocating for alternative security architectures, with China’s Ministry of Foreign Affairs reiterating in official statements during July 2025 that “indivisible security” requires both Russian and Ukrainian assurances. A multipolar compact could theoretically provide security guarantees outside the NATO–Russia binary, though its viability remains speculative without primary documentation of binding commitments.
A sixth scenario is the institutional freeze, in which no peace deal is signed but existing assistance flows and Russian red lines calcify into a long-term standoff. Precedents for such freezes exist: the Korean Armistice Agreement of July 27, 1953, still in effect without a peace treaty, demonstrates that wars can be suspended indefinitely under armistice conditions (Korean Armistice Agreement – July 27, 1953 (UN digital record)). A similar outcome in Ukraine would mean entrenched military lines, indefinite sanctions, continued Western financing through the European Peace Facility, which had disbursed €6.1 billion by May 13, 2025, and a permanent Russian posture treating foreign troops as targets (European Peace Facility: EU support to Ukraine – May 13, 2025).
Each of these scenarios is contingent upon the alignment of legal, political, and institutional factors. The Western model emphasizes host-state consent, assistance without presence, and bilateral guarantees; the Russian model demands treaty-level neutrality and exclusion of foreign troops; multilateral peacekeeping is paralyzed by lack of consent; regional compacts remain embryonic; and armistice freezes appear increasingly plausible given the durability of entrenched positions. By September 2025, official documents confirm that the gap between these models remains unbridgeable, suggesting that the future of peacebuilding in Ukraine will be determined not by convergence but by the endurance of incompatible guarantee architectures, each verified in law and codified in state doctrine.
