This pioneering book, now thoroughly updated to incorporate important research, explains the causes of war through a sustained combination of theoretical insights and detailed case studies. Cashman and Robinson find that while all wars have multiple causes, certain factors typically combine in identifiable "dangerous patterns." Through their examination of World War I, World War II in the Pacific, the Six-Day War, the Indo-Pakistani War of 1971, the Iran-Iraq War, and the US invasion of Iraq, the authors lay out the complex multilevel processes by which disputes between countries erupt into bloody conflicts. Ideal for a range of courses in international relations at both the undergraduate and graduate levels, this focused text clearly explains theory and applies it to concrete case-study examples in a way that allows students to fully understand the origins of war.

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."
