Rising geopolitical tensions. Fracturing arms control agreements. A new era of great-power rivalry.

Nuclear security is back in the spotlight—and the transatlantic alliance is under pressure. Tomáš A. Nagy, Senior Research Fellow for Nuclear, Space, and Missile Defense, and William Alberque, Senior Adjunct Fellow at the Pacific Forum and former Director of NATO’s WMD Arms Control Center unpack how NATO’s nuclear deterrence strategy is evolving—and what must change to meet today’s challenges.

What will it take to strengthen alliance unity?

How are shifts in U.S. force posture shaping deterrence in Europe?

What options are available for Europe to compliment America’s nuclear umbrella?
