White House dispute complicates European leaders' summit on Ukraine

A European summit on Ukraine's defense is now more critical following a diplomatic dispute between U.S. President Donald Trump and Ukrainian President Volodymyr Zelenskyy. Trump criticized Zelenskyy for being ungrateful for U.S. support, complicating European leaders' efforts. British Prime Minister Keir Starmer is hosting the summit, aiming to unite leaders from over a dozen countries to discuss a lasting peace in Ukraine. The meeting follows a series of diplomatic engagements that had initially raised hopes for cooperation. European leaders are now focused on increasing military spending and ensuring support for Ukraine, as concerns grow over U.S. neutrality in negotiations. Starmer and other leaders emphasize the need for Europe to take a more active role in the conflict.
