Cross Domain Deterrence

The complexity of the twenty-first century threat landscape contrasts markedly with the bilateral nuclear bargaining context envisioned by classical deterrence theory. Nuclear and conventional arsenals continue to develop alongside anti-satellite programs, autonomous robotics or drones, cyber operations, biotechnology, and other innovations barely imagined in the early nuclear age. The concept of cross-domain deterrence (CDD) emerged near the end of the George W. Bush administration as policymakers and commanders confronted emerging threats to vital military systems in space and cyberspace. The Pentagon now recognizes five operational environments or so-called domains (land, sea, air, space, and cyberspace), and CDD poses serious problems in practice. In Cross-Domain Deterrence, Erik Gartzke and Jon R. Lindsay assess the theoretical relevance of CDD for the field of International Relations. As a general concept, CDD posits that how actors choose to deter affects the quality of the deterrence they achieve. Contributors to this volume include senior and junior scholars and national security practitioners. Their chapters probe the analytical utility of CDD by examining how differences across, and combinations of, different military and non-military instruments can affect choices and outcomes in coercive policy in historical and contemporary cases.

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.

During the Cold War, many believed that the superpowers shared a conception of strategic stability, a coexistence where both sides would compete for global influence but would be deterred from using nuclear weapons. In actuality, both sides understood strategic stability and deterrence quite differently. Today’s international system is further complicated by more nuclear powers, regional rivalries, and nonstate actors who punch above their weight, but the United States and other nuclear powers still cling to old conceptions of strategic stability. The purpose of this book is to unpack and examine how different states in different regions view strategic stability, the use or non-use of nuclear weapons, and whether or not strategic stability is still a prevailing concept. The contributors to this volume explore policies of current and potential nuclear powers including the United States, Russia, China, India, Iran, Israel, Pakistan, and Saudi Arabia. This volume makes an important contribution toward understanding how nuclear weapons will impact the international system in the twenty-first century and will be useful to students, scholars, and practitioners of nuclear weapons policy.

Global politics in the twenty-first century is complicated by dense economic interdependence, rapid technological innovation, and fierce security competition. How should governments formulate grand strategy in this complex environment? Many strategists look to deterrence as the answer, but how much can we expect of deterrence? Classical deterrence theory developed in response to the nuclear threats of the Cold War, but strategists since have applied it to a variety of threats in the land, sea, air, space, and cyber domains. If war is the continuation of politics by other means, then the diversity of technologies in modern war suggests a diversity of political effects. Some military forces or postures are most useful for "winning" various kinds of wars. Others are effective for "warning" adversaries of consequences or demonstrating resolve. Still others may accomplish these goals at lower political cost, or with greater strategic stability. Deterrence is not a simple strategy, therefore, but a complex relationship between many ends and many means. This book presents findings from a decade-long research program on "cross-domain deterrence." Through a series of theoretical and empirical studies, we explore fundamental trade-offs that have always been implicit in practice but have yet to be synthesized into a general theory of deterrence. Gartzke and Lindsay integrate newly revised and updated versions of published work alongside new work into a holistic framework for understanding how deterrence works--or fails to work--in multiple domains. Their findings show that in deterrence, all good things do not go together.

As the costs of a preemptive foreign policy in Iraq have become clear, strategies such as containment and deterrence have been gaining currency among policy makers. This comprehensive book offers an agenda for the contemporary practice of deterrence—especially as it applies to nuclear weapons—in an increasingly heterogeneous global and political setting. Moving beyond the precepts of traditional deterrence theory, this groundbreaking volume offers insights for the use of deterrence in the modern world, where policy makers may encounter irrational actors, failed states, religious zeal, ambiguous power relationships, and other situations where the traditional rules of statecraft do not apply. A distinguished group of contributors here examines issues such as deterrence among the Great Powers; the problems of regional and nonstate actors; and actors armed with chemical, biological, and nuclear weapons. Complex Deterrence will be a valuable resource for anyone facing the considerable challenge of fostering security and peace in the twenty-first century.

Through the examination of different themes and subjects the book provides an in depth analysis of the concept of deterrence and its utility in dealing effectively with current threats. Although the concept of deterrence precedes the Cold War, in modern times and in its traditional form deterrence is seen as the product of the Cold War, which transformed 'narrow' deterrence approaches into widespread orthodoxy. Increasingly however emerging threats and challenges call into question the traditional concept of deterrence. There are many elements that challenge the concept of deterrence and its effectiveness. For instance it is not just that the concept can be ambiguous and broad, but also there have to be a number of conditions for it to be successfully implemented. This collection contributes to a growing field of research in a relatively under-studied area of interrogating the concept of deterrence itself through a multi-disciplinary approach. Through the use of primary and secondary sources, as well as interviews, this book covers a wide range of disciplinary approaches on deterrence and the contributors cover a broad array of subjects. The research assembled here focuses on deterring extremism, conflict resolution and diplomacy, investigating technological developments, effects of globalisation, social movements, economics, the relationship of resilience to effective deterrence, and the associated complexity of contemporary interdependencies to create a contextualised concept of modern deterrence. Social science and historical methodologies are utilized to gain a comprehensive cross-section of analysis that will reveal the strengths and weaknesses of the use of deterrence as a national security strategy, as well as highlighting the various types of power available for use by the state to create multi-faceted deterrence in order to deal effectively and efficiently with complex emerging challenges.

With many scholars and analysts questioning the relevance of deterrence as a valid strategic concept, this volume moves beyond Cold War nuclear deterrence to show the many ways in which deterrence is applicable to contemporary security. It examines the possibility of applying deterrence theory and practice to space, to cyberspace, and against non-state actors. It also examines the role of nuclear deterrence in the twenty-first century and reaches surprising conclusions.

“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.
