This book presents the evolution of the field of foreign policy analysis and explains the theories that have structured research in this area over the last 50 years. It provides the essentials of emerging theoretical trends, data and methodological pitfalls and major case-studies and is designed to be a key entry point for graduate students, upper-level undergraduates and scholars into the discipline. The volume features an eclectic panorama of different conceptual, theoretical and methodological approaches to foreign political analysis, focusing on different models of analysis such as two-level game analysis, bureaucratic politics, strategic culture, cybernetics, poliheuristic analysis, cognitive mapping, gender studies, groupthink and the systemic sources of foreign policy.
