This is a compelling and rewarding book that makes one wonder why it was not written years ago. Using an explicit conceptualization, rich detail, and a wide range of historical illustrations to depict an analytic focus that has preoccupied observers for a long time, Hudson has done a masterful job of synthesizing diverse materials that will be of great value in both the classroom and policymaking circles.

Valerie Hudson forcefully demonstrates the necessity of engaging in foreign policy analysis grounded in human decision making as the foundation for theory-building in international politics. To build her case she mines critical insights from over a half century of scholarship. New students and seasoned professionals will find her bold integrative perspective both provocative and instructive.
