Understanding Deterrence

For decades, the rational actor model served as the preferred guide for U.S. deterrence policy. It has been a convenient and comforting guide because it requires little detailed knowledge of an opponent’s unique decision-making process and yet typically provides confident generalizations about how deterrence works. The model tends to postulate common decision-making parameters across the globe to reach generalizations about how deterrence will function and the types of forces that will be "stabilizing" or "destabilizing." Yet a broad spectrum of unique factors can influence an opponent’s perceptions and his calculations, and these are not easily captured by the rational actor model. The absence of uniformity means there can be very few deterrence generalizations generated by the use of the rational actor model that are applicable to the entire range of opponents. Understanding Deterrence considers how factors such as psychology, history, religion, ideology, geography, political structure, culture, proliferation and geopolitics can shape a leadership’s decision-making process, in ways that are specific and unique to each opponent. Understanding Deterrence demonstrates how using a multidisciplinary approach to deterrence analysis can better identify and assess factors that influence an opponent’s decision-making process. This identification and assessment process can facilitate the tailoring of deterrence strategies to specific purposes and result in a higher likelihood of success than strategies guided by the generalizations about opponent decision-making typically contained in the rational actor model.

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.

This book bridges the divide between formal and quantitative studies of deterrence by empirically testing and extending perfect deterrence theory. The author focuses on general deterrence, which relates to managing relations between states at all times, not only during crises.

This collection, comprising key works by James J. Wirtz, explains how different threat perceptions can lead to strategic surprise attack, intelligence failure and the failure of deterrence. This volume adopts a strategist’s view of the issue of surprise and intelligence failure by placing these phenomena in the context of conflict between strong and weak actors in world affairs. A two-level theory explains the incentives and perceptions of both parties when significant imbalances of military power exist between potential combatants, and how this situation sets the stage for strategic surprise and intelligence failure to occur. The volume illustrates this theory by applying it to the Kargil Crisis, attacks launched by non-state actors, and by offering a comparison of Pearl Harbor and the September 11, 2001 attacks. It explores the phenomenon of deterrence failure; specifically, how weaker parties in an enduring or nascent conflict come to believe that deterrent threats posed by militarily stronger antagonists will be undermined by various constraints, increasing the attractiveness of utilising surprise attack to achieve their objectives. This work also offers strategies that could mitigate the occurrence of intelligence failure, strategic surprise and the failure of deterrence. This book will be of much interest to students of intelligence studies, strategic studies, security studies and IR in general.

“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.

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 centersâ€"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.

While deterrence is as old as human conflict itself, it became particularly important with the advent of nuclear weapons when armed conflict between the superpowers had the potential to end civilization. Today there is a sense that terrorism has rendered deterrence obsolete and forced the United States to substitute preemption for it. The author illustrates that strategic reality is not simple. He provides both a conceptual framework for understanding deterrence or, more accurately, the psychology of deterrence and policy guidance on how the United States can most effectively use it. The author concludes that an adaptable and flexible military with robust landpower is the only tool that can maintain deterrence.
