This book is an examination of the effect of contemporary wars (such as the 'War on Terror') on civil life at a global level. Contemporary literature on war is mainly devoted to recent changes in the theory and practice of warfare, particular those in which terrorists or insurgents are involved (for example, the 'revolution in military affairs', 'small wars', and so on). On the other hand, today's research on security is focused, among other themes, on the effects of the war on terrorism, and on civil liberties and social control. This volume connects these two fields of research, showing how 'war' and 'security' tend to exchange targets and forms of action as well as personnel (for instance, the spreading use of private contractors in wars and of military experts in the 'struggle for security') in modern society. This shows how, contrary to Clausewitz's belief war should be conceived of as a "continuation of politics by other means", the opposite statement is also true: that politics, insofar as it concerns security, can be defined as the 'continuation of war by other means'. This book will be of much interest to students of critical security studies, war and conflict studies, terrorism studies, sociology and IR in general.
