"Adler and Barnett have edited the most interesting volume in international relations theory in recent memory. They and their co-authors have made a compelling argument for the role of community in shaping security policy, using a variety of empirical cases to back their theoretical claims. The result is a volume that truly honors the legacy of Karl Deutsch." Ethan B. Kapstein, Humphrey Institute
"A major and long overdue contribution to the study of security communities. Adler and Barnett offer a theoretical interpretation that significantly advances understanding of how security communities evolve and how they affect international politics. They also amass a rich selection of historical cases. A must-read for scholars and practitioners interested in the sources of stable peace." Charles A. Kupchan, Georgetown University and Council on Foreign Relations
