Nuclear Weapons in 21st Century U.S. National Security
December 1, 2008
During the Cold War, the purpose of the United States nuclear arsenal was to deter nuclear threats to the United States, primarily from the Soviet Union. Today, in the post-9/11 world, the most urgent nuclear weapon threats to the United States are not from another major power’s deliberate use of them, but instead are from nonstate terrorist actors or from the regional proliferation of such weapons into unreliable hands.
U.S. nuclear policy and strategy in this post-Cold War and post-9/11 security environment have not been well articulated and as a consequence are poorly understood both within and outside American borders. This situation has led to doubts and uncertainties about the roles and missions of nuclear weapons and their value against 21st century security threats, including allies’ uncertainties about U.S. assurances as they relate to emerging nuclear-armed neighboring states. Lacking a coherent and compelling rationale for U.S. nuclear strategy and policy, Congress has been unwilling to fund some Bush administration requests for new nuclear refurbishment efforts (both stockpile and infrastructure). Meanwhile, serious strains on the human, technical, and scientific infrastructure could undermine whatever strategy is ultimately adopted. Clearly, this policy vacuum regarding our nuclear deterrent must be addressed alongside our efforts to prevent further nuclear proliferation.
The purpose of this report is to inform the next administration’s decisionmaking on U.S. nuclear strategy, policy, posture, and related proliferation and arms control issues. Any decision that the United States makes with respect to its own nuclear stockpile and infrastructure must also address how these decisions (and perceptions of those decisions) may affect U.S. efforts to prevent nuclear proliferation and pursue lower global inventories of nuclear weapons. To address 21st century nuclear threats, and growing challenges to sustaining the U.S. nuclear deterrent, the next administration should build a package of nuclear initiatives that can attract broad support both at home and abroad. This study seeks to identify the components of a new centrist way forward to end the post-Cold War drift on U.S. nuclear strategy, policy, and capabilities.
