European leaders called Friday for a reset in relations with the United States as they met at a top security conference where U.S. President Donald Trump’s potshots at traditional transatlantic ties loomed large.

German Chancellor Friedrich Merz urged “a new transatlantic partnership” and French President Emmanuel Macron called for “a strong Europe” as more than 60 leaders gathered for the annual Munich Security Conference.

British Prime Minister Keir Starmer will meanwhile tell the conference Saturday that Europe is “a sleeping giant” and must rely less on the United States for its defense, his office said in a preview of his remarks.
