As for Mr Trump, he again betrayed his underlying bias: sympathy for Russia and indifference to Ukraine. Ahead of the Geneva talks he dismissively said Mr Zelensky “can continue to fight his little heart out” if no agreement were reached, and complained on social media that “UKRAINE ‘LEADERSHIP’ HAS EXPRESSED ZERO GRATITUDE FOR OUR EFFORTS.”

Polish Prime Minister Donald Tusk said “it would be good to know for sure who is the author of the plan,” as tensions over elements that mirror long-standing Russian demands.

US Secretary of State Marco Rubio projected optimism on Sunday after what he described as productive discussions between the American and Ukrainian officials in Geneva, Switzerland, aimed at stopping the war in Ukraine.

The United States and Ukraine said they had created an "updated and refined peace framework" to end the war with Russia that apparently modified an earlier plan drafted by the Trump administration which Kyiv and its allies saw as too sympathetic to Moscow.

A proposed peace plan for Ukraine led by the United States has been met with anguish by many Ukrainians, who fear a post-war amnesty for Russian forces would erase accountability for alleged atrocities.

Trump is "quite pleased" with progress being made, he says, and Rubio adds that he himself is "very optimistic that we're going to get there in a very reasonable period of time very soon", whether it's Thursday, other days, or Monday the following week

U.S., Ukrainian and European officials gathered in Switzerland on Sunday for talks on the contentious American-Russian peace plan put to Kyiv this week.

The president also took aim at former President Joe Biden, arguing that Putin only attacked Ukraine because Biden was president at the time.
