"This provocative, intelligent gem of a book could not be more timely. The authors challenge conventional wisdom about the consequences of America’s wars, from the struggle for independence to the war in Iaq, by marshalling persuasive evidence and by presenting their findings in clear, accessible, and lively prose. Highly recommended for general readers and specialists alike."

Robert J. McMahon, Ralph D. Mershon Professor of History, The Ohio State University

"This is an imaginative, wonderfully written but sober satire on the conceits of an age whose leaders still suppose that war is the way to power over others. Unintended Consequences identifies with the tradition of great scholarship that stretches from Adam Ferguson to Hannah Arendt, in order to show how and why the greatest military power in human history does not know why it does what it does. Bickerton and Hagan brilliantly show that American military actions have typically had effects quite different from what their leaders have said, or imagined. And so Unintended Consequences cleverly helps us grasp why the present Bush administration is sleepwalking its way through problems of its own making—and why, disturbingly, it seems to want nothing more than to bequeath a global crisis to the next administration."

John Keane, professor of politics and director of the Centre for the Study of Democracy, University of Westminster, London

“For too long the western military have looked at Clausewitz as if he can provide the magic silver bullet with regard to strategic military thinking. This book has quite rightly turned conventional thought––hero worship––of that particular military guru upside down. In a world where the threat is no longer likely to be an easily identifiable nation state, conventional military responses are perhaps no longer appropriate. Not only does it prove that the unintended consequences may outweigh the reason for the action in the first instance, but, in the contemporary world, results are likely to be even further divorced from those originally anticipated. It is just what is needed in today’s world––historians who are prepared to stir the hornets’ nest!”

“Mincing no words, these accomplished historians, one Australian and one American, plumb the past, from the American Revolution through to Iraq, keenly demonstrating that U.S. wars have produced unintended, often negative, outcomes. U.S. leaders’ exaggeration of threats, their ignorance of local conditions, and their flawed assumptions that political ‘victory’ can be achieved through military force have led to unforeseen, unwanted consequences. Clausewitz got it wrong: war is not a continuation of policy but rather a radical alteration of policy. Sharply departing from the traditional way of thinking about u.s. wars, Bickerton and Hagan challenge us to understand that war has raised more problems than it has solved.”--Thomas G. Paterson, professor of history emeritus, University of Connecticut, and past president of the Society for Historians of American Foreign Relations (SHAFR)

"Hagan and Bickerton demonstrate that Clausewitz’s nostrum is little more than glib nonsense. . . . The book persuasively demonstrates that there will always be unintended consequences flowing from war."

Bruce Elder | Sydney Morning Herald

"There is little to argue with in this take on history, and the fresh point of view does give certain insights. The two authors also tell their tale well and keep the reader turning pages."

Mark Lawson | Australian Financial Review

"What this book so succinctly points out is that America’s involvement in wars—from the War of Independence through to Iraq (and the authors reject the whole idea of the War on Terror as a war)—has always produced the ’unintended consequences’ of the title. Their analysis of World War II, for example, brilliantly points out the unintended result of how President Truman used the atom bomb—that it effectively started the Cold War."

Steven Carroll | The Age

"What the authors offer is a radical re-interpretation of American military history. This is not a triumphalist book. . . . It is a bold thesis, and one persuasively told in their account of ten different wars the United States has found itself fighting. And of course it is vitally important for the future."

Christopher Coker | Royal United Services Institute for Defence Studies Journal

"Highly relevant. The two authors give an informative summary of the cause and course of American war since 1775, and then analyse their consequences. . . . Essential reading."
