The War Puzzle Revisited

A scientific explanation of the onset and expansion of war and the conditions of peace.

A new scientific explanation of the causes of war using the research findings of the last twenty-five years.

John A. Vasquez's The War Puzzle provided one of the most important scientific analyses of the causes of war of the last two decades. The War Puzzle Revisited updates and extends his groundbreaking work, reviewing research on the onset and expansion of war and the conditions of peace. Vasquez describes systematically those factors associated with wars to see if there is a pattern that suggests why war occurs, and how it might be avoided, delineating the typical path by which relatively equal states have become embroiled in wars in the modern global system. The book uses the large number of empirical findings generated s the basis of its theorizing, and integrates these research findings so as to advance the scientific knowledge of war and peace.

The national security of the United States depends on a secure, reliable and resilient cyberspace. The inclusion of digital systems into every aspect of US national security has been underway since World War II and has increased with the proliferation of Internet-enabled devices. There is an increasing need to develop a robust deterrence framework within which the United States and its allies can dissuade would-be adversaries from engaging in various cyber activities. Yet despite a desire to deter adversaries, the problems associated with dissuasion remain complex, multifaceted, poorly understood and imprecisely specified. Challenges, including credibility, attribution, escalation and conflict management, remain ever-present and challenge the United States in its efforts to foster security in cyberspace. These challenges need to be addressed in a deliberate and multidisciplinary approach that combines political and technical realities to provide a robust set of policy options to decision makers. The Cyber Deterrence Problem brings together a multidisciplinary team of scholars with expertise in computer science, deterrence theory, cognitive psychology, intelligence studies and conflict management to analyze and develop a robust assessment of the necessary requirements and attributes for achieving deterrence in cyberspace. Beyond simply addressing the base challenges associated with deterrence, many of the chapters also propose strategies and tactics to enhance deterrence in cyberspace and emphasize conceptualizing how the United States deters adversaries.

Laura Sjoberg positions gender and gender subordination as key factors in the making and fighting of global conflict. Through the lens ofgender, she examines the meaning, causes, practices, and experiences of war, building a more inclusive approach to the analysis of violent conflict between states. Considering war at the international, state, substate, and individual levels, Sjoberg's feminist perspective elevates a number of causal variables in war decision-making. These include structural gender inequality, cycles of gendered violence, state masculine posturing, the often overlooked role of emotion in political interactions, gendered understandings of power, and states' mistaken perception of their own autonomy and unitary nature. Gendering Global Conflict also calls attention to understudied spaces that can be sites of war, such as the workplace, the household, and even the bedroom. Her findings show gender to be a linchpin of even the most tedious and seemingly bland tactical and logistical decisions in violent conflict. Armed with that information, Sjoberg undertakes the task of redefining and reintroducing critical readings of war's political, economic, and humanitarian dimensions, developing the beginnings of a feminist theory of war.

This book presents a collection of new and updated essays on what has come to be known as the territorial explanation of war. The book argues that a key both to peace and to war lies in understanding the role territory plays as a source of conflict and inter-group violence. Of all the issues that spark conflict, territorial disputes have the highest probability of escalating to war. War, however, is hardly inevitable; much depends on how territorial issues are handled. More importantly, settling territorial disputes and establishing mutually recognized boundaries can produce long periods of peace between neighbors, even if other salient issues arise. While territory is not the only cause of war and wars arise from other issues, territory is one of the main causes of war, and learning how to manage it, can, in principle, eliminate an entire class of wars. This book will be of great interest to all students of war and conflict studies, causes of war and peace, international security and strategic studies. John A. Vasquez is Thomas B.

International Relations theory assumes that the struggle for power is not only ahistorical but that international politics is necessarily the realm of a perpetual struggle for power between states. However, by looking beyond the state, the study of global politics may itself reveal the importance of alternative imaginaries just as historically salient as that of the state system. In particular, this book argues that a specific racial imaginary has, over the past two centuries, cut across politically defined state boundaries to legitimate practices of genocidal violence against so-called "enemy races." In Global Race War, Alexander D. Barder shows how the very idea of global order was based on racial hierarchy and difference. Barder traces the emergence of this global racial hierarchy from the early 19th century to the present to explain how a historical racial global order unraveled over the first half of the 20th century, continued during the Cold War, and reemerged during the Global War on Terror. As Barder shows, imperial, racial, and geopolitical orders intersected over time in ways that violently tore apart the imperial and sovereign state system and continue to haunt politics today. Examining global politics in terms of race and racial violence reveals a different spatial topology across domestic and global politics. Moreover, global histories of racial hierarchy and violence have important implications for understanding the continued salience of race within Western polities. Global Race War revisits two centuries of international history to show the important consequences of a global racial imaginary that continues to reverberate across time and space.

Now in a thoroughly revised and updated edition, this classic text presents a comprehensive survey of the many alternative theories that attempt to explain the causes of interstate war. For each theory, Greg Cashman examines the arguments and counterarguments, considers the empirical evidence and counterevidence generated by social-science research, looks at historical applications of the theory, and discusses the theory’s implications for restraining international violence. Among the questions he explores are: Are humans aggressive by nature? Do individual differences among leaders matter? How might poor decision making procedures lead to war? Why do leaders engage in seemingly risky and irrational policies that end in war? Why do states with internal conflicts seem to become entangled in wars with their neighbors? What roles do nationalism and ethnicity play in international conflict? What kinds of countries are most likely to become involved in war? Why have certain pairs of countries been particularly war-prone over the centuries? Can strong states deter war? Can we find any patterns in the way that war breaks out? How do balances of power or changes in balances of power make war more likely? Do social scientists currently have an answer to the question of what causes war? Cashman examines theories of war at the individual, substate, nation-state, dyadic, and international systems level of analysis. Written in a clear and accessible style, this interdisciplinary text will be essential reading for all students of international relations.
