For decades, films such as WarGames and The Terminator have warned that the combination of artificial intelligence and nuclear weapons might be a recipe for an apocalypse. Might these prophecies of doom become reality in coming decades? Using insights from computer science, Deterrence under Uncertainty: Artificial Intelligence and Nuclear Warfare evaluates how AI could make nuclear war winnable, and whether that possibility is likely. Detailed chapters explain how the landscape of nuclear deterrence is changing and debunks the myths of machine intelligence and nuclear weapons. This book gives a practitioner's perspective on how artificial intelligence and other emerging technologies could change the role of nuclear weapons in international relations.

The dangerous, decades-long arms race between the United States and the Soviet Union during the Cold War begged a fundamental question: how did these superpowers actually plan to survive a nuclear strike? In Armageddon Insurance, the first historical account of Soviet civil defense and a pioneering reappraisal of its American counterpart, Edward M. Geist compares how the two superpowers tried, and mostly failed, to reinforce their societies to withstand the ultimate catastrophe. Drawing on previously unexamined documents from archives in America, Russia, and Ukraine, Geist places these civil defense programs in their political and cultural contexts, demonstrating how each country's efforts reflected its cultural preoccupations and blind spots and revealing how American and Soviet civil defense related to profound issues of nuclear strategy and national values. This work challenges prevailing historical assumptions and unearths the ways Moscow and Washington developed nuclear weapons policies based not on rational strategic or technical considerations but in power struggles between different institutions pursuing their own narrow self-interests.

Applying advances in game theory to the study of nuclear deterrence, Robert Powell examines the foundations of deterrence theory. Game-theoretic analysis allows the author to explore some of the most complex and problematic issues in deterrence theory, including the effects of first-strike advantages, limited retaliation, and the number of nuclear powers in the international system on the dynamics of escalation.

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 greater use of artificial intelligence (AI) and autonomous systems by the militaries of the world has the potential to affect deterrence strategies and escalation dynamics in crises and conflicts. Up until now, deterrence has involved humans trying to dissuade other humans from taking particular courses of action. What happens when the thinking and decision processes involved are no longer purely human? How might dynamics change when decisions and actions can be taken at machine speeds? How might AI and autonomy affect the ways that countries have developed to signal one another about the potential use of force? What are potential areas for miscalculation and unintended consequences, and unwanted escalation in particular? This exploratory report provides an initial examination of how AI and autonomous systems could affect deterrence and escalation in conventional crises and conflicts. Findings suggest that the machine decisionmaking can result in inadvertent escalation or altered deterrence dynamics, due to the speed of machine decisionmaking, the ways in which it differs from human understanding, the willingness of many countries to use autonomous systems, our relative inexperience with them, and continued developments of these capabilities. Current planning and development efforts have not kept pace with how to handle the potentially destabilizing or escalatory issues associated with these new technologies, and it is essential that planners and decisionmakers begin to think about these issues before fielded systems are engaged in conflict.

In the literature of diplomacy and military strategy, there has long been a gulf between the concepts of deterrence and defense. Glenn Snyder bridges this gulf, offering a systematic analysis of the two ideas, with the aim of integrating them in a framework of theory. He proposes criteria for making rational decisions in national security policy and deals with the critical issue of the balance between deterrence of, and defense against, military attacks. The author augments the scattered literature on the subject with original contributions on this increasingly important facet of international relations. Originally published in 1961. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

As a concept, deterrence has launched a thousand books and articles. It has dominated Western strategic thinking for more than four decades. In this important and groundbreaking new book, Lawrence Freedman develops a distinctive approach to the evaluation of deterrence as both a state of mind and a strategic option. This approach is applied to post-cold war crisis management, and the utility and relevance of the concept is addressed in relation to US strategic practice post-9/11, particularly in the light of the apparent preference of the Bush Administration for the alternative concept of pre-emption. The study of deterrence has been hampered by the weight of the intellectual baggage accumulated since the end of the Second World War. Exaggerated notions of what deterrence might achieve were developed, only to be to knocked down by academic critique. In this book, Freedman charts the evolution of the contemporary concept of deterrence, and discusses whether - and how - it still has relevance in today's world. He considers constructivist as well as realist approaches and draws on criminological as well as strategic studies literature to develop a concept of a norms-based, as opposed to an interest-based, deterrence. This book will be essential reading for students of politics and international relations as well as all those interested in contemporary strategic thought.
