U.S. Urges Ukraine-Russia Peace Proposals, Warns of Withdrawal from Mediation

U.S. Secretary of State Marco Rubio called on Russia and Ukraine to present concrete proposals to end the war, warning that the U.S. may step back from mediation if no progress is made. Speaking at the United Nations, U.S. diplomat John Kelley said Russia had continued high-profile strikes, leading to civilian casualties. He emphasized that the responsibility for peace lies with both Moscow and Kyiv, stating the U.S. will support any serious effort toward lasting peace.

State Department spokeswoman Tammy Bruce echoed Rubio’s urgency, noting that the U.S. expects real diplomatic action soon. She added that President Donald Trump, who has prioritized a swift resolution, may pull back U.S. involvement if talks stall. Despite both sides trying to show progress, mutual blame persists at the U.N.

Russian President Vladimir Putin announced a three-day ceasefire from May 8–10 to commemorate the Soviet World War II victory. Ukraine, however, criticized the gesture as insufficient, calling for a 30-day ceasefire beginning immediately. Bruce stated the U.S. seeks a “complete, durable ceasefire,” not symbolic pauses.

Trump has shifted U.S. policy since taking office, pressuring Ukraine for concessions while easing rhetoric toward Russia, though his stance is hardening. Ukraine and European allies recently rejected parts of U.S. peace proposals and submitted counteroffers on sanctions and territorial issues.

At the Security Council, U.N. political chief Rosemary DiCarlo noted a slight hope for peace but pointed out continued hostilities despite temporary truces. Western powers praised U.S. efforts but condemned Russia’s aggression. Russia denied targeting civilians and accused Ukraine of rejecting fair proposals. Ukrainian officials reiterated they would not accept peace based on surrender or the recognition of occupied territories like Crimea.
