The debate on no-first-use of nuclear weapons has been conducted on a number of fronts. First use of nuclear weapons has come under challenge from many different directions: from church synods, from international lawyers, in debates at the United Nations, and from strategic thinkers. Originally published in 1984, this book takes stock for and against no-first-use and examines the political, military and arms control implications of such a commitment.

Since the Hiroshima and Nagasaki attacks, no state has unleashed nuclear weapons. What explains this? According to the author, the answer lies in a prohibition inherent in the tradition of non-use, a time-honored obligation that has been adhered to by all nuclear states—thanks to a consensus view that use would have a catastrophic impact on humankind, the environment, and the reputation of the user. The book offers an in-depth analysis of the nuclear policies of the U.S., Russia, China, the UK, France, India, Israel, and Pakistan and assesses the contributions of these states to the rise and persistence of the tradition of nuclear non-use. It examines the influence of the tradition on the behavior of nuclear and non-nuclear states in crises and wars, and explores the tradition's implications for nuclear non-proliferation regimes, deterrence theory, and policy. And it concludes by discussing the future of the tradition in the current global security environment.

On January 27, 2017, President Donald Trump directed Secretary of Defense James Mattis to initiate a new Nuclear Posture Review (NPR). The President made clear that his first priority is to protect the United States, allies, and partners. He also emphasized both the long-term goal of eliminating nuclear weapons and the requirement that the United States have modern, flexible, and resilient nuclear capabilities that are safe and secure until such a time as nuclear weapons can prudently be eliminated from the world.The United States remains committed to its efforts in support of the ultimate global elimination of nuclear, biological, and chemical weapons. It has reduced the nuclear stockpile by over 85 percent since the height of the Cold War and deployed no new nuclear capabilities for over two decades. Nevertheless, global threat conditions have worsened markedly since the most recent 2010 NPR, including increasingly explicit nuclear threats from potential adversaries. The United States now faces a more diverse and advanced nuclear-threat environment than ever before, with considerable dynamism in potential adversaries' development and deployment programs for nuclear weapons and delivery systems.

Deterrence as a strategic concept evolved during the Cold War. During that period, deterrence strategy was aimed mainly at preventing aggression against the United States and its close allies by the hostile Communist power centers--the Union of Soviet Socialist Republics (USSR) and its allies, Communist China and North Korea. In particular, the strategy was devised to prevent aggression involving nuclear attack by the USSR or China. Since the end of the Cold War, the risk of war among the major powers has subsided to the lowest point in modern history. Still, the changing nature of the threats to American and allied security interests has stimulated a considerable broadening of the deterrence concept. Post-Cold War Conflict Deterrence examines the meaning of deterrence in this new environment and identifies key elements of a post-Cold War deterrence strategy and the critical issues in devising such a strategy. It further examines the significance of these findings for the U.S. Navy and Marine Corps. Quantitative and qualitative measures to support judgments about the potential success or failure of deterrence are identified. Such measures will bear on the suitability of the naval forces to meet the deterrence objectives. The capabilities of U.S. naval forces that especially bear on the deterrence objectives also are examined. Finally, the book examines the utility of models, games, and simulations as decision aids in improving the naval forces' understanding of situations in which deterrence must be used and in improving the potential success of deterrence actions.

The debate about appropriate purposes and policies for U.S. nuclear weapons has been under way since the beginning of the nuclear age. With the end of the Cold War, the debate has entered a new phase, propelled by the post-Cold War transformations of the international political landscape. This volume--based on an exhaustive reexamination of issues addressed in The Future of the U.S.-Soviet Nuclear Relationship (NRC, 1991)--describes the state to which U.S. and Russian nuclear forces and policies have evolved since the Cold War ended. The book evaluates a regime of progressive constraints for future U.S. nuclear weapons policy that includes further reductions in nuclear forces, changes in nuclear operations to preserve deterrence but enhance operational safety, and measures to help prevent proliferation of nuclear weapons. In addition, it examines the conditions and means by which comprehensive nuclear disarmament could become feasible and desirable.

The President has the power to end the world in minutes. Right now, no one can stop him. Since the Truman administration, America has been one "push of a button" away from nuclear war—a decision that rests solely in the hands of the President. Without waiting for approval from Congress or even the Secretary of Defense, the President can unleash America's entire nuclear arsenal. Almost every governmental process is subject to institutional checks and balances. Why is potential nuclear annihilation the exception to the rule? For decades, glitches and slip-ups have threatened to trigger nuclear winter: misinformation, false alarms, hacked warning systems, or even an unstable President. And a new nuclear arms race has begun, threatening us all. At the height of the Cold War, Russia and the United States each built up arsenals exceeding 30,000 nuclear weapons, armed and ready to destroy each other—despite the fact that just a few hundred are necessary to end life on earth. From authors William J. Perry, Secretary of Defense in the Clinton administration and Undersecretary of Defense for Research and Engineering in the Carter administration, and Tom Z. Collina, the Director of Policy at Ploughshares Fund, a global security foundation in Washington, DC, The Button recounts the terrifying history of nuclear launch authority, from the faulty 46-cent microchip that nearly caused World War III to President Trump's tweet about his "much bigger & more powerful" button. Perry and Collina share their firsthand experience on the front lines of the nation's nuclear history and provide illuminating interviews with former President Bill Clinton, former Secretary of Defense Jim Mattis, Congressman Adam Smith, Nobel Peace Prize winner Beatrice Fihn, senior Obama administration officials, and many others. Written in an accessible and authoritative voice, The Button reveals the shocking tales and sobering facts of nuclear executive authority throughout the atomic age, delivering a powerful condemnation against ever leaving explosive power this devastating under any one person's thumb.
