'Focusing on the dark side of the democratic peace, this book inquires into the ambivalences that have arisen when democracies fight non-democracies. Focusing on different types of war since the end of the Cold War, this theoretically self-conscious, well-designed, data-rich, methodologically sophisticated, tightly argued and morally nuanced book opens up a new avenue for research that both enriches and unsettles the conventional wisdom. Its conclusions pose important intellectual challenges that will influence international relations research and graduate instructions for years to come.' Peter J. Katzenstein, Walter S. Carpenter, Jr Professor of International Studies, Cornell University
