Trump's team threatens to exit Ukraine negotiations amid growing rift

The United States of America may withdraw from the negotiation process to resolve the full-scale war in Ukraine if White House leader Donald Trump believes he is being "used," warns White House Special Envoy for Ukraine Keith Kellogg on ABC News.
"I think when you talk about walking away if he believes he's being used and that there is no hope in progress going forward, he goes: 'We’re done with this. Europe, we leave it over to you'," Kellogg stated, commenting on Trump’s threats to exit the negotiation process.
Negotiations on resolving war in Ukraine
Over the past few months, the United States has held a series of separate meetings with representatives from both Ukraine and Russia regarding a resolution to the full-scale war. During these talks, Washington proposed a full ceasefire to Kyiv, and Ukraine immediately supported the initiative. Russia, in turn, began putting forward its own demands.
Subsequently, Moscow repeatedly initiated so-called "ceasefires," but never adhered to them.
On May 16, direct talks between Ukraine and Russia were held in Türkiye for the first time in several years. During these talks, Kyiv and Moscow agreed on a large-scale prisoner exchange under the "1,000 for 1,000" formula. The exchange was carried out in three stages over the past weekend.
It’s also worth noting that at the start of his second presidential term, Trump repeatedly criticized Ukraine and President Volodymyr Zelenskyy. However, in recent months, his rhetoric toward Russia has noticeably shifted becoming significantly tougher.
