This text aims to expand the growing scholarly debate around genocide by exploring the involvement of the USA and other liberal "Western" democracies in activities supposedly restricted to totalitarian and authoritarian regimes. It examines the question of where responsibility for genocide resides, the variety of domestic and international institutional responses, and the moral basis for accusing Western countries of complicity. A large number of original case studies make clear how broadly conceived the subject ought to be; the wide range of state behaviours that can be criticised as constituting genocide, war crimes, or comparable mass violations of human rights; and the remedies that ought to be available. At a time when terrorism has become a near universal focus of public attention, this book shows why the actions of the West, both in centuries past and the Cold War era, have excited such widespread resentment and hatred around the world.
