President Donald Trump said Monday he is not ruling out deploying U.S. forces to Ukraine as part of security guarantees to underpin a future peace agreement with Russia. “We’ll let you know that maybe later today … we’ll be involved,” the president told reporters when asked whether American troops could participate in the effort. The remarks followed a meeting in the Oval Office with Ukrainian President Volodymyr Zelenskyy that was also attended by several European heads of state. Trump said European countries would be “the first line of defense” but promised “a lot of help” and “protection” from Washington, signaling a potential shift from his earlier reluctance to commit ground forces abroad. Kyiv has long sought binding security assurances as an alternative to near-term NATO membership. Trump’s comments come three days after his summit with Russian President Vladimir Putin in Alaska, which ended without a cease-fire. White House officials said discussions on a peace framework—and on any U.S. troop contribution—are continuing.
