In answering these central questions, contributors focus on two complementary analytical approaches. The first examines the perceptions of systemic changes by America’s allies: how are US allies framing this issue and what kind of political discourse is emerging with regards to it? The second approach focuses on the concrete foreign policy and defence strategies put forward by these allies. The book explores the extent to which US allies are willing to support US hegemony and considers the democratic allies’ understanding of the international structure, their relations to the United States, and their own aspirations in this changing world order. This book will be of interest to general readers as well as scholars and students of US foreign policy, foreign policy analysis and International Relations.
