While the Cold War is long past, the importance of arms control in Russo-American relations and the related issue of nuclear weapons for Russia remain vital concerns. Indeed, without an appreciation of the multiple dimensions of the latter, progress in the former domain is inconceivable. With this in mind, following essays explore many, if not all, of the issues connected with Russia's relatively greater reliance on nuclear weapons for its security. As such, they constitute an important contribution to the analysis of the Obama administration's reset policy, Russo-American relations, Russian foreign and defense policy, and international security in both Europe and Asia. Additionally, questions concerning the approach taken by other nuclear power nations in reference to the arms control agenda provide a crucial backdrop for the progress toward curbing the proliferation of nuclear weapons, a long-standing central goal of U.S. security policy.
