This book chronicles the policy debates on Islamism in the United States over the course of time, providing a comprehensive account of the origins of policy followed by a balanced critique and recommendations for change. It then delves deeper into the US political scene to analyze the historical, political, cultural, and security issues that might help explain America's preoccupation with Islam and Muslims. Furthermore, the author sheds much light on the multiplicity of regional and international factors, such as the political decay of the Middle Eastern state and the end of the Cold War, that shape the thinking of US officials about the contemporary Islamist phenomenon. In addition to examining the domestic, regional, and international context of US Islam policy, the book applies and tests the pronouncements of US officials in four representative case studies - Iran, Algeria, Egypt and Turkey. Finally, Gerges addresses the clash of civilizations debate and assesses the relative weight of culture and values in US officials' words and deeds on Islamism.
