European NATO members acknowledge the need to enhance their defense capabilities amid the ongoing conflict in Ukraine and a shift in U.S. focus towards Asia. Concerns are heightened by the potential return of former President Trump, who threatened to withdraw defense support from non-paying allies. While European states have made progress in restoring deterrence against Russia, there is still a significant need to reduce reliance on the U.S. This includes increased defense spending, bolstering troop numbers, addressing strategic gaps, and reevaluating the role of the American nuclear umbrella. These efforts are crucial for Europe to establish a more independent and robust defense posture.
