Jonathan Caverley challenges our image of democracies – and mass publics – as being relatively averse to war. The costs of war, he correctly argues, are not distributed evenly across all citizens. Those who are taxed less heavily than others or do not serve in the military, he reasons, will be less averse to war and will support more aggressive foreign policies, favor more military spending, prefer more capitalized armies that substitute equipment and technology for individual soldiers, and fight insurgencies inefficiently. He tests this argument using public opinion surveys linking income to attitudes and case studies of the expansion of the franchise in nineteenth-century Britain and the overly capitalized wars fought by the United States in Vietnam and Israel in southern Lebanon. This is an original and insightful contribution to the literature on war and international security more generally, and is an outstanding example of how mixed-method research designs are often more persuasive than any single method design. It deserves a broad audience, especially as it appears that the United States and others will be confronted with many ‘small wars’ and insurgencies in the years ahead. If Caverley is right, we are doomed to fight these wars badly and ineffectively.
