The Russia-Ukraine war entered its fourth year without a ceasefire, peace framework, or credible negotiating process accepted by all relevant parties. This was not for lack of peace proposals: Zelensky presented a 10-point formula; China released a 12-point framework; Turkey hosted talks; Switzerland organized an 92-nation summit; Trump promised to end the war in 24 hours. The gap between these proposals and an actual peace lies in the fundamental incompatibility of what Russia demands (recognition of its military gains, Ukrainian neutrality) and what Ukraine requires (territorial restoration and security guarantees that would prevent a future attack). Understanding the diplomatic history requires examining each major initiative and the structural obstacles each encountered.
The Istanbul Near-Agreement of 2022
The most advanced diplomatic exchange of the conflict occurred in Istanbul in late March–early April 2022, as Russian forces were withdrawing from the Kyiv Oblast following their failed northern axis assault. Ukrainian and Russian delegating teams, facilitated by Turkey, held multiple rounds of talks that progressed toward a preliminary framework: Ukraine would commit to neutrality (abandoning NATO membership), accept limits on its military size, and receive security guarantees (not full NATO Article 5 equivalent) from a group of guarantor states including permanent UN Security Council members; Russia would withdraw to pre-February-24 lines (the 23 February 2022 positions, not necessarily 2014 Crimea/Donbas positions). Both Ukrainian and Russian sources described approaching a draft agreement in late March 2022. Why talks collapsed: UK Prime Minister Boris Johnson visited Kyiv in early April 2022, and Ukrainian officials subsequently hardened their position; Ukraine later confirmed foreign allies counseled against signing; Russia rejected the framing that its Kyiv withdrawal was a negotiating concession (calling it a "goodwill gesture"), and the discovery of the Bucha massacre (1 April 2022) made any agreement with Russia politically unsellable to the Ukrainian public. Both sides later disputed whether a deal was close. The episode established the pre-condition dynamic that shaped all subsequent diplomacy.
Zelensky's 10-Point Peace Formula
At the G20 Bali summit in November 2022, President Zelensky presented Ukraine's 10-point Peace Formula as the framework for ending the war on terms that would not repeat the Minsk Agreements experience. The ten points: (1) Nuclear safety — IAEA control over all Ukrainian nuclear sites; (2) Food security — protecting Ukrainian agricultural exports; (3) Energy security — restoring destroyed infrastructure; (4) Release of all prisoners and deportees — including Ukrainian children; (5) UN Charter implementation — restoring Ukraine's territorial integrity within 1991 internationally recognized borders; (6) Russian troop withdrawal — from all occupied territory; (7) Justice — special tribunal for aggression, ICC for war crimes; (8) Ecocide — environmental damage reparations; (9) Prevention of escalation — specific security architecture; (10) Confirmation of war's end — binding peace agreement. Ukraine offered each of these ten points as separate tracks capable of parallelized international progress — meaning humanitarian elements (food, nuclear safety, POWs) could advance while the more difficult territorial questions remained unresolved. This framing allowed Ukraine to show diplomatic engagement and international coalition-building while not conceding the territorial core. Russia dismissed the formula as a Ukrainian "ultimatum."
Coalition Formula Summits
Ukraine convened a series of consultative summits to build international consensus around the Peace Formula's principles: (1) Copenhagen Process — hosted by Denmark, June 2023; approximately 15 nations; working-group format; identified areas of possible broad international agreement within the Peace Formula pillars; (2) Malta Process — hosted by Malta, October 2023; approximately 65 nations represented at senior official level; expanded the coalition significantly; (3) Davos (World Economic Forum) — January 2024; senior representatives from approximately 83 countries discussed Peace Formula implementation; growing engagement from non-Western nations including from Africa, Latin America, and Southeast Asia; (4) Additional bilateral Ukraine diplomacy — Zelensky's extensive travel schedule through 2022–2024 visited over 60 countries, always including presentations of the Peace Formula and requests for explicit endorsement. The goal of the coalition-building exercise: to arrive at the Switzerland summit with a prepared list of supporting nations, demonstrating that Russia's "Global South" partner narrative (that Western nations were isolated in supporting Ukraine) was false, and that Ukraine's principles had genuine international support across the developing world.
Switzerland Bürgenstock Summit: June 2024
The Switzerland peace summit (Bürgenstock resort, June 15–16, 2024) represented the most prominent multilateral diplomatic event of the war: 92 nations represented; heads of state or government from approximately 57; UN Secretary-General Guterres attending; US Vice President Harris leading the American delegation. Russia was not invited (at Ukraine's insistence). China declined to attend after Russia lobbied against participation. Outcome: a joint communiqué signed by approximately 78–80 of the 92 delegations (exact signatory list varied by document), specifically endorsing three pillars: (1) Nuclear safety — IAEA must be allowed full access to Zaporizhzhia Nuclear Power Plant; (2) Food security — UN principles for protecting civilian shipping lanes; (3) POW and deportee exchanges — all prisoners of war and forcibly deported civilians, especially children, must be returned. The territorial and UN Charter restoration pillars were not included in the communiqué due to opposition from several Global South attendees unwilling to endorse language implying Russia should withdraw from all occupied territories. Assessment: the summit was organizationally successful (92 nations is a significant coalition) but diplomatically limited (the three agreed pillars were those least threatening to Russia and most favorable to building a broad coalition; the hard questions on territory were avoided). Russia called it an "anti-Russia" event with no legitimacy. China's absence reduced its international impact.
China's 12-Point Peace Plan
On 24 February 2023 (the one-year anniversary of Russia's full-scale invasion), China released a 12-Point Position Paper on the Political Settlement of the Ukraine Crisis. The plan's central elements: calls for ceasefire and resumption of peace talks; opposition to "unilateral sanctions" (China's position that Western sanctions on Russia are illegitimate); call for ending "Cold War mentality"; respecting "sovereignty of all countries" (language that both sides interpret differently regarding Russian-occupied Ukrainian territory); opposition to nuclear weapons use or threats; protection of civilian infrastructure; facilitation of humanitarian corridors. Western assessment: vague, without enforcement mechanism, avoiding explicit condemnation of Russia's invasion, with language on sanctions that primarily served Russian interests. Ukraine's response: the plan could serve as a starting framework but required clarity on whether China recognized Russia's invasion as a violation of Ukrainian sovereignty — which China consistently declined to provide. The plan gave China diplomatic cover as a "peace supporter" without requiring any specific commitments. A subsequent China-Brazil joint framework (May 2023) was similarly vague. China's diplomatic ambiguity throughout the conflict — trading with Russia while avoiding direct military support — complicated Western efforts to hold Beijing accountable for enabling Russian war capacity.
Trump's Peace Pressure 2024–2025
During his 2024 presidential campaign and following his November 2024 election victory, Donald Trump consistently promised to end the war quickly — at times claiming he could do so in 24 hours. Trump's approach priorities: ending the conflict quickly rather than on specific territorial terms; skepticism toward NATO burden-sharing (frequently suggesting Ukraine's allies should pay more); personal relationship with Putin suggesting possible direct deals bypassing multilateral formats; appointment of Keith Kellogg as special envoy for Ukraine/Russia. Post-inauguration (January 2025) Trump administration policy: direct outreach to Russia; pressure on Ukraine to accept a ceasefire on terms that could include territorial concessions; public statements questioning continuing military aid at current levels; the February 2025 Oval Office meeting with Zelensky became a significant public confrontation — Trump and Vice President Vance publicly criticized Zelensky for insufficient gratitude and unwillingness to negotiate, with Zelensky's responses broadcast live globally. European allies reacted by accelerating their own Ukraine support commitments, interpreting the confrontation as evidence of reduced American reliability. Ukraine-Trump relations remained tense through early 2026, with European partners increasingly coordinating separately on Ukraine support.
Red Lines: All Parties
The unbridgeable gap that has prevented negotiated settlement: Putin's stated minimum requirements (evolved through public statements and back-channel communications): Ukrainian neutrality and abandonment of NATO/EU membership path; Russian recognition/annexation of all four oblasts claimed (Donetsk, Luhansk, Zaporizhzhia, Kherson including areas not controlled by Russia); Ukrainian demilitarization to specified limits; no Western military bases in Ukraine; legal amnesty for Russian actions since 2014. Zelensky's red lines: no recognition of Russian sovereignty over any occupied Ukrainian territory without referendum; no NATO/EU membership path abandonment (Ukraine argues this is its legal right under international law); no demilitarization beyond what genuine peace and sovereignty requires; real security guarantees with enforcement mechanisms, not paper assurances; ICC and war crimes accountability continuing. Biden administration red lines: no US negotiation with Russia on Ukraine's behalf; no security commitments that automatically trigger US military involvement; NATO membership during the conflict not offered; continued arms and financial support within those constraints. These three sets of incompatible requirements explain why, despite extensive diplomatic activity, no negotiating process that all relevant parties accept as legitimate has commenced through early 2026.
Budapest Memorandum Context
Understanding Ukraine's security guarantee demands requires understanding the Budapest Memorandum. In December 1994, Ukraine signed the Budapest Memorandum on Security Assurances, agreeing to surrender the roughly 1,900 Soviet strategic nuclear warheads on its territory (making Ukraine the world's third-largest nuclear power at the time) in exchange for security assurances from the United States, United Kingdom, and Russia. The assurances committed the signatories to: respect Ukrainian independence, sovereignty, and existing borders; refrain from the threat or use of force against Ukraine; and bring the matter to the UN Security Council if Ukraine was threatened or attacked by the other signatories. Russia violated all three commitments with the 2014 Crimea annexation and especially the 2022 full-scale invasion. The US and UK fulfilled the Security Council commitment formally but Russia's veto power made it effectively non-functional. No military response was provided. Ukraine gave up nuclear weapons for assurances that proved worthless when challenged. This experience is the foundational reason Ukraine insists any future security arrangement must have legally binding military commitment with enforcement mechanisms, not political declarations. The Budapest Memorandum failure is also cited by several US analysts as a negative example affecting global nuclear non-proliferation — if surrendering nuclear weapons produces only violated paper promises, future potential nuclear states will draw specific deterrence conclusions.
Security Guarantee Debates
The central unresolved question in Ukraine's diplomatic position is what security guarantees could replace nuclear deterrence and NATO membership for ensuring post-war Ukrainian security. Options debated within the Western security community: (1) Full NATO membership — Zelensky's preferred outcome; provides strongest guarantee (Article 5 collective defense); opposed by Germany and Hungary who feared Article 5 entanglement in a conflict with Russia; the NATO Vilnius Communiqué (July 2023) promised membership "when conditions are met" without timeline; (2) Bilateral security treaties — the UK and France signed preliminary security partnership agreements with Ukraine in early 2024, committing to specified military support and consultation in the event of future aggression; these are the most concrete security commitments Ukraine received from NATO members short of Article 5; the US did not sign comparable binding agreements under Biden; (3) Pre-positioned forces model — deploying NATO national contingents on Ukrainian soil as tripwire deterrence (Franco/UK proposal discussed 2024–2025); the "European Security Force" concept; (4) Israeli model — strong bilateral security relationship, constant weapons resupply, intelligence sharing, without formal treaty obligation; some US analysts proposed this as a reachable compromise; Ukraine's response: Israel has nuclear deterrence as ultimate backstop; Ukraine does not. The security guarantee debate remained the central unresolved diplomatic question through early 2026.
Frequently Asked Questions
What is Zelensky's Peace Formula?
Zelensky's 10-point Peace Formula (announced G20 in Bali, November 2022) sets out Ukraine's framework for ending the war: (1) nuclear safety; (2) food security; (3) energy security; (4) release of all prisoners and deportees; (5) implementation of UN Charter/territorial restoration to 1991 borders; (6) Russian withdrawal; (7) justice/ICC; (8) ecocide prevention; (9) prevention of escalation/new security architecture; (10) formal confirmation of war's end. Ukraine presents these as parallel tracks — humanitarian pillars can advance separately from the harder territorial questions — while the complete formula represents Ukraine's non-negotiable starting position for any political settlement with Russia.
Why did the Switzerland Summit fail to end the war?
The June 2024 Bürgenstock Summit was not designed to directly negotiate with Russia — it was a coalition-building consultation among Ukraine and its supporters. Russia was not invited; China did not attend as a signatory. The joint communiqué endorsed only three non-territorial pillars (nuclear safety, food security, POW/deportee exchanges) because the full Peace Formula's territorial demands were too divisive for a broad multilateral consensus. Russia dismissed the summit as illegitimate. It demonstrated Ukraine can assemble a 92-nation coalition but provided no mechanism for bringing Russia to negotiate on terms Ukraine could accept. Assessment: useful for Ukraine's international position; not a pathway to a settlement.
What security guarantees is Ukraine seeking?
Ukraine seeks binding security guarantees with enforcement mechanisms — not paper assurances. The Budapest Memorandum (1994) provided written US/UK/Russia commitments to respect Ukrainian sovereignty in exchange for Ukraine surrendering Soviet nuclear weapons; Russia violated them with no effective consequence. Ukraine therefore demands: (1) preferably full NATO Article 5 membership; (2) alternatively, bilateral security treaties with major NATO powers (US, UK, France, Germany, Poland) committing to specified military responses to future aggression; (3) pre-positioned NATO national forces on Ukrainian soil; (4) pre-stocked weapons and ready intelligence sharing. Ukraine's position: a ceasefire without real security guarantees simply resets the clock for the next Russian attack — reproducing Minsk 2015 on a larger scale.
