Issues of defence politics and policy have long been at the forefront of political agendas and defining of international affairs. However, the dramatic changes to the global system that have taken place since the end of the Cold War and parrticularly since the terror attacks on the USA on 11 September 2001 have amplified the world's attention toward political and policy issues of national, regional and global security. The focus of this volume is on examining the fundamental causes of, and defence policy responses to this new 'post-9/11' security environment. Edited by Isaiah (Ike) Wilson III and James J. F. Forest of the US Military Academy, West Point, USA, this volume is international in scope, with pieces written by experts in the field, offering a collection of up-to-date and balanced insights on key contemporary issues of concern to defence policymakers. The book will be an invaluable reference tool for academics and students, researchers in international relations, policymakers, media professionals and government officials.
