Introduction
Recent trends have brought the nuclear nonproliferation regime to a moment of grave crisis. The regime is under siege from both rogue states and nonstate actors, and its core bargain between the nuclear haves and have-nots continues to erode. Bolstering international restraints on the world's deadliest weapons will require the United States and its international partners to adopt realistic, concrete steps to strengthen and close gaps in existing treaty regimes, institutions, and partnerships.
These recommendations reflect the views of Stewart M. Patrick, director of the program on international institutions and global governance.
