Ukraine's Zelenskyy stresses gratitude for U.S. after clash with Trump, as Europe shows new solidarity against Russia

Ukraine's President Volodymyr Zelenskyy said his country felt the full support of its European allies after a summit in London over the weekend, as he reiterated the need for Western security guarantees as part of any agreement to secure a lasting end to the war sparked by Russia's full-scale invasion of his country three years ago. Ukraine fears Russia would renege on any peace deal that doesn't carry with it the threat that Ukraine's partners would come to its aid in case of a violation.

"For peace to be real, we need real security guarantees. And this is the position of all of Europe – the entire continent," Zelenskyy said in a social media post Monday, three days after President Trump and Vice President JD Vance accused him of being "disrespectful" and failing to offer thanks during a contentious Oval Office meeting with news cameras rolling.

"Of course, we understand the importance of America, and we are grateful for all the support we've received from the United States," Zelenskyy said Monday. "There has not been a day when we haven't felt gratitude. It's gratitude for the preservation of our independence – our resilience in Ukraine is based on what our partners are doing for us – and for their own security. What we need is peace, not endless war. And that's why we say security guarantees are the key to this."
