Although Russia, the United States, and American allies have been loath to downsize their nuclear arsenals, deep reductions would not undermine a nation’s security since arsenal size has little bearing on effectiveness of deterrence.
Since the five permanent members of the United Nations Security Council are nuclear weapon states, they struggle in their attempts to convince other nations, like Iran and North Korea, not to develop a nuclear weapon program.
Achieving a genuinely collaborative approach to missile defense would address a common threat to the Euro-Atlantic region and help remove the misgivings that are blocking progress toward a common security space.
Mutual understanding and cooperation between the United States, China, and other countries is essential for overcoming the challenges facing the nonproliferation regime.
