For decades, the reigning scholarly wisdom about nuclear weapons policy has been that the United States only needs the ability to absorb an enemy nuclear attack and still be able to respond with a devastating counterattack. So long as the US, or any other nation, retains such an assured retaliation capability, no sane leader would intentionally launch a nuclear attack against it, and nuclear deterrence will hold. According to this theory, possessing more weapons than necessary for a second-strike capability is illogical. This argument is reasonable, but, when compared to the empirical record, it raises an important puzzle. Empirically, we see that the United States has always maintained a nuclear posture that is much more robust than a mere second-strike capability. In The Logic of American Nuclear Strategy, Matthew Kroenig challenges the conventional wisdom and explains why a robust nuclear posture, above and beyond a mere second-strike capability, contributes to a state's national security goals. In fact, when a state has a robust nuclear weapons force, such a capability reduces its expected costs in a war, provides it with bargaining leverage, and ultimately enhances nuclear deterrence. This book provides a novel theoretical explanation for why military nuclear advantages translate into geopolitical advantages. In so doing, it helps resolve one of the most-intractable puzzles in international security studies. Buoyed by an innovative thesis and a vast array of historical and quantitative evidence, The Logic of American Nuclear Strategy will force scholars to reconsider their basic assumptions about the logic of nuclear deterrence.

A leading international security strategist offers a compelling new way to "think about the unthinkable." The cold war ended more than two decades ago, and with its end came a reduction in the threat of nuclear weapons—a luxury that we can no longer indulge. It's not just the threat of Iran getting the bomb or North Korea doing something rash; the whole complexion of global power politics is changing because of the reemergence of nuclear weapons as a vital element of statecraft and power politics. In short, we have entered the second nuclear age. In this provocative and agenda-setting book, Paul Bracken of Yale University argues that we need to pay renewed attention to nuclear weapons and how their presence will transform the way crises develop and escalate. He draws on his years of experience analyzing defense strategy to make the case that the United States needs to start thinking seriously about these issues once again, especially as new countries acquire nuclear capabilities. He walks us through war-game scenarios that are all too realistic, to show how nuclear weapons are changing the calculus of power politics, and he offers an incisive tour of the Middle East, South Asia, and East Asia to underscore how the United States must not allow itself to be unprepared for managing such crises. Frank in its tone and farsighted in its analysis, The Second Nuclear Age is the essential guide to the new rules of international politics.

Leading analysts have predicted for decades that nuclear weapons would help pacify international politics. The core notion is that countries protected by these fearsome weapons can stop competing so intensely with their adversaries: they can end their arms races, scale back their alliances, and stop jockeying for strategic territory. But rarely have theory and practice been so opposed. Why do international relations in the nuclear age remain so competitive? Indeed, why are today's major geopolitical rivalries intensifying? In The Myth of the Nuclear Revolution, Keir A. Lieber and Daryl G. Press tackle the central puzzle of the nuclear age: the persistence of intense geopolitical competition in the shadow of nuclear weapons. They explain why the Cold War superpowers raced so feverishly against each other; why the creation of "mutual assured destruction" does not ensure peace; and why the rapid technological changes of the 21st century will weaken deterrence in critical hotspots around the world. By explaining how the nuclear revolution falls short, Lieber and Press discover answers to the most pressing questions about deterrence in the coming decades: how much capability is required for a reliable nuclear deterrent, how conventional conflicts may become nuclear wars, and how great care is required now to prevent new technology from ushering in an age of nuclear instability.

From the author of the classic The Wizards of Armageddon and Pulitzer Prize finalist comes the definitive history of American policy on nuclear war—and Presidents’ actions in nuclear crises—from Truman to Trump. Fred Kaplan, hailed by The New York Times as “a rare combination of defense intellectual and pugnacious reporter,” takes us into the White House Situation Room, the Joint Chiefs of Staff’s “Tank” in the Pentagon, and the vast chambers of Strategic Command to bring us the untold stories—based on exclusive interviews and previously classified documents—of how America’s presidents and generals have thought about, threatened, broached, and just barely avoided nuclear war from the dawn of the atomic age until today. Kaplan’s historical research and deep reporting will stand as the permanent record of politics. Discussing theories that have dominated nightmare scenarios from Hiroshima and Nagasaki, Kaplan presents the unthinkable in terms of mass destruction and demonstrates how the nuclear war reality will not go away, regardless of the dire consequences.

“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

Are nuclear weapons useful for coercive diplomacy? This book argues that they are useful for deterrence but not for offensive purposes.

In a vitally important book for anyone interested in nuclear proliferation, defense strategy, or international security, Matthew Kroenig points out that nearly every country with a nuclear weapons arsenal received substantial help at some point from a more advanced nuclear state. Why do some countries help others to develop nuclear weapons? Many analysts assume that nuclear transfers are driven by economic considerations. States in dire economic need, they suggest, export sensitive nuclear materials and technology—and ignore the security risk—in a desperate search for hard currency. Kroenig challenges this conventional wisdom. He finds that state decisions to provide sensitive nuclear assistance are the result of a coherent, strategic logic. The spread of nuclear weapons threatens powerful states more than it threatens weak states, and these differential effects of nuclear proliferation encourage countries to provide sensitive nuclear assistance under certain strategic conditions. Countries are more likely to export sensitive nuclear materials and technology when it would have the effect of constraining an enemy and less likely to do so when it would threaten themselves. In Exporting the Bomb, Kroenig examines the most important historical cases, including France's nuclear assistance to Israel in the 1950s and 1960s; the Soviet Union's sensitive transfers to China from 1958 to 1960; China's nuclear aid to Pakistan in the 1980s; and Pakistan's recent technology transfers, with the help of "rogue" scientist A. Q. Khan, from 1987 to 2002. Understanding why states provide sensitive nuclear assistance not only adds to our knowledge of international politics but also aids in international efforts to control the spread of nuclear weapons.

We are at a critical juncture in world politics. Nuclear strategy and policy have risen to the top of the global policy agenda, and issues ranging from a nuclear Iran to the global zero movement are generating sharp debate. The historical origins of our contemporary nuclear world are deeply consequential for contemporary policy, but it is crucial that decisions are made on the basis of fact rather than myth and misapprehension. In Nuclear Statecraft, Francis J. Gavin challenges key elements of the widely accepted narrative about the history of the atomic age and the consequences of the nuclear revolution. On the basis of recently declassified documents, Gavin reassesses the strategy of flexible response, the influence of nuclear weapons during the Berlin Crisis, the origins of and motivations for U.S. nuclear nonproliferation policy, and how to assess the nuclear dangers we face today. In case after case, he finds that we know far less than we think we do about our nuclear history. Archival evidence makes it clear that decision makers were more concerned about underlying geopolitical questions than about the strategic dynamic between two nuclear superpowers. Gavin's rigorous historical work not only tells us what happened in the past but also offers a powerful tool to explain how nuclear weapons influence international relations. Nuclear Statecraft provides a solid foundation for future policymaking.
