This book will illustrate that despite the variations of nuclear tensions during the Cold War period-from nuclear inception, to mass proliferation, to arms control treaties and détente, through to an intensification and "reasonable" conclusion (the INF Treaty and START being case points)-the "lessons" over the last decade are quickly being unlearned. Given debates surrounding the emerging "new Cold War," the deterioration of relations between Russia and the United States, and the concurrent challenges being made by key nuclear states in obfuscating arms control mechanisms, this book attempts to provide a much needed revisit into US presidential foreign policy during the Cold War. Across nine chapters, the monograph traces the United States' nuclear diplomacy and Presidential strategic thought, transitioning across the early period of Cold War arms racing through to the era's defining conclusion. It will reveal that notwithstanding the heightened periods when great power conflict seemed imminent,  arms control fora and seminal agreements were able to be devised, implemented, and provided a needed base in bringing down the specter of a cataclysmic nuclear war, as well as improving bilateral relations. This volume will be of great interest to scholars and students of American foreign policy, diplomatic history, security studies and international relations.
