Rethinking the Unthinkable examines the future direction of nuclear arms control in the post-Cold War security environment. Believing that the new environment requires a radical rethinking of the purpose and role of nuclear weapons in international politics, the contributors address many fundamental issues influencing further US, Russian and European nuclear arms reductions. This volume is a product of the Project on Rethinking Arms Control, sponsored by the Center for International and Security Studies in Maryland.
