This succinct yet comprehensive introduction to Foreign Policy Analysis (FPA) is geared toward advanced undergraduate and beginning graduate students. Cogently written, clearly organized, and filled with illuminating examples, the third edition has been thoroughly revised and updated. Beginning with an overview of this broad field of study, Hudson and Day consider theory and research at multiple levels of analysis, including personality and psychology of foreign policy decision makers, small group dynamics, the organizational process, bureaucratic politics, domestic politics, cultural and societal influences, national attributes, and system-level effects on foreign policy. The authors also examine the promise and frustration of theoretical integration in FPA and overview promising new work by non-North American scholars.
