Drawing on critical geopolitics and related strands of social theory, this book combines new case studies with theoretical and methodological reflections on the geographical analysis of security and insecurity. It brings together a mixture of early career and more established scholars and interprets security and the war on terror across a number of domains, including: international law, religion, migration, development, diaspora, art, nature and social movements. At a time when powerful projects of globalization and security continue to extend their reach over an increasingly wide circle of people and places, the book demonstrates the relevance of critical geographical imaginations to an interrogation of the present.
