Abstract
This text examines the dynamics that shape foreign policy using international relations (IR) theory. Combining theories and case studies with actors, it explores the grand principles at work in foreign policy, both as a form of state behaviour and as an intellectual field. Chapters illustrate the complementarity between individual, state, and structural dynamics of IR, and levels of analysis found in foreign policy analysis. They discuss the relevance to foreign policy of the main IR theories: realism, liberalism, and constructivism, alongside the tool of discourse analysis. This introduction provides an overview of the contemporary relevance of the study of foreign policy; some of the definitional issues concerning the study of foreign policy; and the book’s updated organization.
