This book explores Puritanism and its continuing influence on U.S. and military law in the Global War on Terror, exploring connections between Puritanism and notions of responsibility in relation to military crimes, superstitious practices within the military, and urges for revenge. Engaging with the work of figures such as Durkheim, Fauconnet and Weber, it draws on primary data gathered through participation and observation at the U.S. Army courts-martial following events at Abu Ghraib, Operation Iron Triangle, the Baghdad canal killings and a war crimes case in Afghanistan, to show how Puritan cultural habits color and shape both American military actions and the ways in which these actions are perceived by the American public. A theoretically sophisticated examination of the cultural tendencies that shape military conduct and justice in the context of a contemporary global conflict, The Puritan Culture of America’s Military will appeal to scholars across the social sciences with interests in social theory and sociology, cultural studies, politics and international relations and military studies.
