Why and how is America contested by Europe? This new book answers this question and contributes to a better understanding of contemporary transatlantic tensions. Adopting different theoretical perspectives, the leading contributors to this volume assess the European discontent with America and relate this to the unilateral turn of US foreign policy in the 2000s. American unilateralism is interpreted by all the authors as the expression of a new conservative nationalism which has been growing in the country since the 1970s and became culturally hegemonic after 9/11. They explore the following key areas: the rise of American conservative nationalism; US foreign policy; transatlantic relations; anti-Americanism; the Iraq War; and the future of American political and cultural hegemony. This book will be vital reading for students of international relations, foreign policy analysis, American and European politics.
