This book explores the crucial relationship between security and identity in a changing Europe. It covers a series of key policy issues, including NATO enlargement, EU integration, war in the Balkans and Russia's uncertain future. This new agenda is explored through a range of theoretical approaches, from traditional realist to social constructivist and postmodern interpretations. Security and Identity in Europe thus offers an excellent guide to contending theories of international relations and provides innovative insights for students seeking to understand a changing Europe at the beginning of the new millennium.
