Brussels—U.S. President Donald Trump greets French President Emmanuel Macron before a NATO Summit on May 25. The two shared an awkward handshake that fueled speculation about tensions between the U.S. president and his European counterparts, and Macron later appeared to dodge a handshake with Trump in favor of a hug with German Chancellor Angela Merkel. At the summit, Trump lectured NATO members on the need to spend more on defense and avoided explicitly endorsing the alliance’s Article 5, which commits all members to act in defense of any ally under attack.
