Britain's military forces have rarely been busier. It is therefore crucial to understand the developing trends and underlying assumptions of British Defence Policy, in regard to both foreign policy and international security. This volume, which covers both the Blair and Brown eras in defence policy making, places developments post 11 September in a wider context, assessing the impact of key personalities and events on a range of issues, notably the perennial concern of military overstretch. By critically appraising contemporary developments, and examining the driving policy in specific cases, this volume provides a relevant and up-to-date assessment of this vital policy area. As well as being contemporary in its analysis, the work is also comprehensive in scope, embracing both policy objectives - such as the expeditionary strategy and the desire to be a bridge between the US and EU - and the instruments that underpin such policy.
