These essays by nuclear policy experts provide “a speculative but serious and well-informed journey through a variety of scenarios and contingencies” (Foreign Affairs). Recent decades have seen a slow but steady increase in nuclear armed states, and in the seemingly less constrained policy goals of some of the newer “rogue” states in the international system. The authors of On Limited Nuclear War in the 21st Century argue that a time may come when one of these states makes the conscious decision that using a nuclear weapon against the United States, its allies, or forward deployed forces in the context of a crisis or a regional conventional conflict may be in its interests. They assert that we are unprepared for these types of limited nuclear wars and that it is urgent we rethink the theory, policy, and implementation of force related to our approaches to this type of engagement. Together they critique Cold War doctrine on limited nuclear war and consider a number of the key concepts that should govern our approach to limited nuclear conflict in the future. These include identifying the factors likely to lead to limited nuclear war; examining the geopolitics of future conflict scenarios that might lead to small-scale nuclear use; and assessing strategies for crisis management and escalation control. Finally, they consider a range of strategies and operational concepts for countering, controlling, or containing limited nuclear war. “A series of trenchant essays that deconstruct a critical national security challenge that most of us wish did not exist. Assembling a star-studded cast of scholars, analysts, and policy practitioners, Larsen and Kartchner have produced some of the most important new thinking on an old topic.” —H-Diplo

“An excellent contribution to the debate on the future role of nuclear weapons and nuclear deterrence in American foreign policy.” ―Contemporary Security Policy This book is a counter to the conventional wisdom that the United States can and should do more to reduce both the role of nuclear weapons in its security strategies and the number of weapons in its arsenal. The case against nuclear weapons has been made on many grounds—including historical, political, and moral. But, Brad Roberts argues, it has not so far been informed by the experience of the United States since the Cold War in trying to adapt deterrence to a changed world, and to create the conditions that would allow further significant changes to U.S. nuclear policy and posture. Drawing on the author’s experience in the making and implementation of U.S. policy in the Obama administration, this book examines that real-world experience and finds important lessons for the disarmament enterprise. Central conclusions of the work are that other nuclear-armed states are not prepared to join the United States in making reductions, and that unilateral steps by the United States to disarm further would be harmful to its interests and those of its allies. The book ultimately argues in favor of patience and persistence in the implementation of a balanced approach to nuclear strategy that encompasses political efforts to reduce nuclear dangers along with military efforts to deter them. “Well-researched and carefully argued.” ―Foreign Affairs

For more than forty years, the United States has maintained a public commitment to nuclear disarmament, and every president from Ronald Reagan to Barack Obama has gradually reduced the size of America's nuclear forces. Yet even now, over two decades after the end of the Cold War, the United States maintains a huge nuclear arsenal on high alert and ready for war. The Americans, like the Russians, the Chinese, and other major nuclear powers, continue to retain a deep faith in the political and military value of nuclear force, and this belief remains enshrined at the center of U.S. defense policy regardless of the radical changes that have taken place in international politics. In No Use, national security scholar Thomas M. Nichols offers a lucid, accessible reexamination of the role of nuclear weapons and their prominence in U.S. security strategy. Nichols explains why strategies built for the Cold War have survived into the twenty-first century, and he illustrates how America's nearly unshakable belief in the utility of nuclear arms has hindered U.S. and international attempts to slow the nuclear programs of volatile regimes in North Korea and Iran. From a solid historical foundation, Nichols makes the compelling argument that to end the danger of worldwide nuclear holocaust, the United States must take the lead in abandoning unrealistic threats of nuclear force and then create a new and more stable approach to deterrence for the twenty-first century.

“This is a brilliant and hardheaded book. It will frighten those who prefer not to dwell on the unthinkable and infuriate those who have taken refuge in stereotypes and moral attitudinizing.”—Gordon A. Craig, New York Times Book Review Originally published more than fifty years ago, this landmark book explores the ways in which military capabilities—real or imagined—are used, skillfully or clumsily, as bargaining power. Anne-Marie Slaughter’s new introduction to the work shows how Schelling’s framework—conceived of in a time of superpowers and mutually assured destruction—still applies to our multipolar world, where wars are fought as much online as on the ground.

This open access volume surveys the state of the field to examine whether a fifth wave of deterrence theory is emerging. Bringing together insights from world-leading experts from three continents, the volume identifies the most pressing strategic challenges, frames theoretical concepts, and describes new strategies. The use and utility of deterrence in today’s strategic environment is a topic of paramount concern to scholars, strategists and policymakers. Ours is a period of considerable strategic turbulence, which in recent years has featured a renewed emphasis on nuclear weapons used in defence postures across different theatres; a dramatic growth in the scale of military cyber capabilities and the frequency with which these are used; and rapid technological progress including the proliferation of long-range strike and unmanned systems. These military-strategic developments occur in a polarized international system, where cooperation between leading powers on arms control regimes is breaking down, states widely make use of hybrid conflict strategies, and the number of internationalized intrastate proxy conflicts has quintupled over the past two decades. Contemporary conflict actors exploit a wider gamut of coercive instruments, which they apply across a wider range of domains. The prevalence of multi-domain coercion across but also beyond traditional dimensions of armed conflict raises an important question: what does effective deterrence look like in the 21st century? Answering that question requires a re-appraisal of key theoretical concepts and dominant strategies of Western and non-Western actors in order to assess how they hold up in today’s world.

Deterrence remains a primary doctrine for dealing with the threat of nuclear weapons in the 21st century. The author reviews the history of nuclear deterrence and calls for a renewed intellectual effort to address the relevance of concepts such as first strike, escalation, extended deterrence, and other Cold War-era strategies in today's complex world of additional superpowers, smaller nuclear powers, and nonstate actors.

“Perry has long been one of the more strenuous advocates for confronting the dangers of the nuclear age, and his engaging memoir explains why.” —Foreign Affairs My Journey at the Nuclear Brink is a continuation of former Secretary of Defense William J. Perry's efforts to keep the world safe from a nuclear catastrophe. It tells the story of his coming of age in the nuclear era, his role in trying to shape and contain it, and how his thinking has changed about the threat these weapons pose. In a remarkable career, Perry has dealt firsthand with the changing nuclear threat. Decades of experience and special access to top-secret knowledge of strategic nuclear options have given Perry a unique, and chilling, vantage point from which to conclude that nuclear weapons endanger our security rather than securing it. This book traces his thought process as he journeys from the Cuban Missile Crisis, to crafting a defense strategy in the Carter Administration to offset the Soviets’ numeric superiority in conventional forces, to presiding over the dismantling of more than 8,000 nuclear weapons in the Clinton Administration, and to his creation in 2007, with George Shultz, Sam Nunn, and Henry Kissinger, of the Nuclear Security Project to articulate their vision of a world free from nuclear weapons and to lay out the urgent steps needed to reduce nuclear dangers. “Perry’s authoritative memoir. . . . is a clear, sobering and, for many, surprising warning that the danger of a nuclear catastrophe today is actually greater than it was during that era of U.S.-Soviet competition…a significant and insightful memoir and a necessary read.” —Mortimer B. Zuckerman, U.S. News & World Report
