European leaders to join Zelenskiy in Washington as Trump presses Ukraine deal

European leaders will join Volodymyr Zelenskiy to meet Donald Trump in Washington, they said on Sunday, seeking to shore up Zelenskiy's position as the U.S. president presses Ukraine to accept a quick peace deal to end Europe's deadliest war in 80 years.

Trump is leaning on Zelenskiy to strike an agreement after he met Kremlin chief Vladimir Putin in Alaska and emerged more aligned with Moscow on seeking a peace deal instead of a ceasefire first. Trump and Zelenskiy will meet on Monday.

"If peace is not going to be possible here and this is just going to continue on as a war, people will continue to die by the thousands ... we may unfortunately wind up there, but we don't want to wind up there," Secretary of State Marco Rubio said in an interview with CBS' "Face the Nation."

Trump on Sunday promised "BIG PROGRESS ON RUSSIA" in a social media post without specifying what this might be.

Sources briefed on Moscow's thinking told Reuters the U.S. and Russian leaders have discussed proposals for Russia to relinquish tiny pockets of occupied Ukraine in exchange for Kyiv ceding a swathe of fortified land in the east and freezing the front lines elsewhere.

Top Trump officials hinted that the fate of Ukraine's eastern Donbas region - which incorporates Donetsk and Luhansk and which is already mostly under Russian control - was on the line, while some sort of defensive pact was also on the table.

"We were able to win the following concession, that the United States could offer Article 5-like protection," Trump envoy Steve Witkoff told CNN's "State of the Union" on Sunday, suggesting this would be in lieu of Ukraine seeking NATO membership. "The United States could offer Article 5 protection, which was the first time we had ever heard the Russians agree to that."

Article 5 of NATO's founding treaty enshrines the principle of collective defense - the notion that an attack on a single member is considered an attack on them all.

That pledge may not be enough to sway leaders in Kyiv to sign over Donbas. Ukraine's borders were already meant to have been guaranteed when Ukraine surrendered a Soviet-era nuclear arsenal in 1994, and it proved to be little deterrent when Russia absorbed Crimea in 2014 and then launched its full-scale invasion in 2022. The war has now dragged on for 3-1/2 years and killed or wounded more than 1 million people.
