Foreign Policy Analysis is the study of how states engage with the international environment. It focuses on how and why individual foreign policy decision-makers act in response to particular stimuli, and what the consequences of their actions are. It consequently operates at a different level of analysis to most International Relations sub-fields, and often pays more attention to the specific characteristics of events than to their general implications. For these reasons, FPA forms something of a bridge between the study of domestic and international politics. This module introduces students to FPA, and to the foreign policy analyst’s ‘toolkit’; a set of theories, approaches, and methods that together help us interpret, understand, and explain how states engage in international politics.
