President Trump's April 29 phone call with Vladimir Putin on a potential Ukraine ceasefire for Russia's Victory Day drew a cautious response from Volodymyr Zelenskyy, who demanded details and countered with a long-term truce proposal, highlighting persistent bilateral frictions absent trilateral coordination. These separate diplomatic exchanges reflect stalled peace talks amid frontline stalemates, unresolved territorial claims, and mutual accusations of prolonging the conflict, with no announced summits involving all three leaders. Earlier 2026 U.S. mediation efforts, including distinct meetings with each side and missed June deadlines, have yielded no joint appearances, anchoring trader consensus at 86% "No" despite occasional de-escalation signals.
