Challenges and Dilemmas of European Union is a readable, informative volume for students and instructors of introductory and intermediate courses in international relations and comparative politics. Since the daily activities of the European Union cut across the comparative/IR distinction, the book will prove useful in both courses. Caporaso is careful to begin with a detailed chapter that provides readers with important, historical, background information. He then deals with prevalent dilemmas such as the struggle between sovereign states and the thick networks provided by international institutions and international economic interdependencies, the external impact of the European Union, the political changes that have occurred due to developments in economic integration, changes in the relations between employers and workers, and changes in the nature of social democracy, or the welfare state. Caporaso also includes a discussion of the implications of the aforementioned dilemmas by providing alternative scenarios, rather than by making formidable predictions.
