Trump will call for increasing NATO defense spending to 5% of GDP, but differences between member states could generate tensions at the summit.

At the NATO summit, Trump will announce a pledge to increase defense spending to 5% of GDP, which would be a victory for him. Although European leaders want to please him, there are disagreements over the timetable for implementation, with some countries asking for waivers. The summit has been shortened to 24 hours to avoid clashes, and talks focus on meeting Trump's expectations in the context of the war in Ukraine. Increased spending will target both Europe's long-term defense and balancing influence within the alliance.
