The Abu Dhabi talks open a rare diplomatic channel between Russia and Ukraine, but the prospect of peace is already colliding with the terms of the settlement. Washington wants a deal that can end the fighting; Kyiv and its European partners fear that a rushed agreement could instead formalize Russia’s gains and weaken the continent’s defenses.

U.S. officials are presenting the negotiations as an effort to create a new European security architecture, potentially including guarantees for Ukraine comparable to NATO’s Article 5 and renewed dialogue between Moscow and the alliance. They argue that the existing system has failed because it did not prevent the war, and that a “final end” requires a framework designed to reduce future escalation.¹ Yet the proposal remains deliberately vague, while critics question what would actually trigger a U.S. military response and whether Washington is prepared to commit the resources involved.

President Donald Trump’s emphasis is more immediate: ending the killing. He says both sides show a “very strong inclination” to stop the war, while Ukrainian President Volodymyr Zelenskyy argues that recent battlefield gains have improved Kyiv’s negotiating position.² The contrast is consequential. Moscow continues to demand Ukraine’s withdrawal from the entire Donbas, whereas Kyiv rejects territorial concessions without firm security guarantees.

Europe, meanwhile, is resisting the idea that Washington and Moscow can redesign the continent’s security order over its head. France says Europeans will be represented because no discussion about the continent’s future can ignore their “expectations and demands.”³ That position aligns with Kyiv’s concern: peace may require compromise, but a settlement that rewards coercion without credible protection could become only a pause before the next war. The talks therefore test not just whether the parties can stop fighting, but whose definition of security will shape what follows.
