The terrorist attacks of 11 September 2001 marked a turning point in international politics, representing a new type of threat that could not easily be anticipated or prevented through state-based structures of security alone. Opening up interdisciplinary conversations between strategic, economic, ethical and legal approaches to global terrorism, this edited book recognises a fundamental issue: while major crises initially tend to reinforce old thinking and behavioural patterns, they also allow societies to challenge and overcome entrenched habits, thereby creating the foundations for a new and perhaps more peaceful future. The objective of this volume is to address the issues that are at stake in this dual process of political closure, and to therefore rethink how states can respond to terrorist threats. The contributors offer a unique combination, being drawn from leading conceptual theorists to policy-oriented analysts, from senior academics to junior researchers. The book explores how terrorism has had a profound impact on how security is being understood and implemented, and uses a range of hitherto neglected sources of insight, such as those between political, economic, legal and ethical factors, to examine the nature and meaning of security in a rapidly changing world. This book will be of much interest to students of Terrorism Studies, Security Studies, International Law and International Relations in general.Davies, Sara E. is the author of 'Security Reform And the War on Terror ', published 2007 under ISBN 9780415368452 and ISBN 0415368456.
