Pentagon review spurs European rethink on NATO spending and basing

European NATO allies are reassessing security priorities as a Pentagon review of burden-sharing and basing unfolds. Allies have already stepped up defense spending—roughly $90 billion more in 2025 than 2024—and are funneling arms and air-defense capabilities to Ukraine. The review’s specifics remain unclear ahead of upcoming NATO discussions, with cautions against tying security commitments to spending while stressing the need for threat-based force positioning and access in Europe.
