The very existence of diversionary wars is hotly contested in the press and among political scientists. Yet no book has so far tackled the key questions of whether leaders deliberately provoke conflicts abroad to distract the public from problems at home, or whether such gambles offer a more effective response to domestic discontent than appeasing opposition groups with political or economic concessions. Diversionary War addresses these questions by reinterpreting key historical examples of diversionary war—such as Argentina's 1982 Falklands Islands invasion and U.S. President James Buchanan's decision to send troops to Mormon Utah in 1857. It breaks new ground by demonstrating that the use of diversionary tactics is, at best, an ineffectual strategy for managing civil unrest, and draws important conclusions for policymakers—identifying several new, and sometimes counterintuitive, avenues by which embattled states can be pushed toward adopting alternative political, social, or economic strategies for managing domestic unrest.
