As the United States adjusts to a changing global balance of power, nuclear deterrence is poised to return to a level of importance in U.S. national security not seen since the end of the Cold War. However, U.S. nuclear strategy will have to contend with emerging issues like arms control in a multipolar world, the evolution of strategic technology, and the new contours of great power competition. America's Nuclear Crossroads: A Forward-Looking Anthology is a useful reference tool for policymakers and laypeople alike as they navigate an increasingly complex nuclear security environment. The debates and policy decisions that play out over the next few years will likely affect America's nuclear deterrence and arms control strategies for decades to come. This anthology offers a wide view of the most pressing challenges the United States is facing at this crossroads. While it cannot resolve every emerging problem, we hope America's Nuclear Crossroads sparks a broader dialogue and offers some initial recommendations for solving said challenges.
