What Causes 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.

What causes war? How can military conflicts best be prevented? In this book, Stephen Van Evera frames five conditions that increase the risk of interstate war: false optimism about the likely outcome of a war, a first-strike advantage, fluctuation in the relative power of states, circumstances that allow nations to parlay one conquest into another, and circumstances that make conquest easy. According to Van Evera, all but one of these conditions—false optimism—rarely occur today, but policymakers often erroneously believe in their existence. He argues that these misperceptions are responsible for many modern wars, and explores both World Wars, the Korean War, and the 1967 Mideast War as test cases. Finally, he assesses the possibility of nuclear war by applying all five hypotheses to its potential onset. Van Evera's book demonstrates that ideas from the Realist paradigm can offer strong explanations for international conflict and valuable prescriptions for its control.

On War is a treatise about a military art which Prussian officer Carl Philipp Gottflib von Clausewitz had been working on for 15 years. It is commonly believed that Clausewitz’s treatise had a greater impact on military leaders of the late XIX and XX centuries than any other book. In reality, this book is an overturn in the war theory. The work is notable for its brightness, narration details as well as hard criticism of many war events. The author dedicates a special place in his work to politics, its influence on the war events, the dependence how the war finishes on powers and weaknesses of particular politicians and military leaders. There is a good reason why his famous phrase “the war is the continuation of the politics, but with other, strong arm methods” is still relevant.

Written by leading scholars in the field, Causes of War provides the first comprehensive analysis of the leading theories relating to the origins of both interstate and civil wars. Utilizes historical examples to illustrate individual theories throughout Includes an analysis of theories of civil wars as well as interstate wars -- one of the only texts to do both Written by two former International Studies Association Presidents

Breaks the theories of international conflict down into categories: those that seek to explain whether man is naturally warlike; those which focus on political processes within states; those addressing national and international conflict; and those which examine the world order itself.

The Paraguayan War (1864?70) was the deadliest and most extensive interstate war ever fought in Latin America. The conflict involving Paraguay, Uruguay, Argentina, and Brazil killed hundreds of thousands of people and had dire consequences for the Paraguayan dictator Francisco Solano L¢pez and his nation. Though the Paraguayan War stirs the same emotions in South Americans as does the Civil War in the United States, there have been few significant investigations of the war available in English. In this first of two volumes, Thomas L. Whigham provides an engrossing and comprehensive account of the war's origins and early campaigns, and he guides the reader through the complexities of South American nationalism, military development, and political intrigue. Whigham portrays the conflict as bloody and inexcusable, though it paved the way for more modern societies in the continent. The Paraguayan War fills an important gap in our understanding of Latin American history.

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.
