Despite Russian aggression in Ukraine and growing threats along NATO’s southern flank, many European allies find it difficult to increase their defense capabilities and meet the commitments they made at the Wales Summit. To address this important challenge, the Atlantic Council produced its Alliance at Risk report, which draws together noted experts and former senior officials to examine the vulnerabilities in European defense and provide recommendations on the way forward. The project highlights six leading nations from NATO’s north, south, east, and west, which also serves to illuminate the many perspectives and diverse defense priorities that exists within the Alliance today.
