Conspiracy theory and American foreign policy examines the relationship between secrecy, power and interpretation around international controversy, where foreign policy orthodoxy comes up hard against alternative interpretations. It does so in the context of US foreign policy during the War on Terror, a conflict that was covert and conspiratorial to its core. Offering a new dimension to debates on post-truth politics, this book critically examines the 'Arab-Muslim paranoia narrative': the view that Arab-Muslim resentment towards America is motivated to some degree by a paranoid perception of American power in the Middle East. This narrative is traced from its roots in a post-War liberal understanding of populism through to foreign policy debates about the origins of 9/11, to the strategic heart of the Bush Administration's War of Ideas. Balancing conceptual innovation with detailed case analysis, Aistrope provides a window into the ideological commitments of the US War on Terror. Offering a fascinating insight into conspiracy and paranoia, this book is essential reading for those interested in the relationship between secrecy, power, and contemporary politics.
