An analysis that takes the complexity of British defence policy apart to view its anatomy and show how policy is made in this area. British defence policy is in a phase of great transition as the country confronts its Brexit future and also as world politics becomes more threatening and potentially unstable. This book uses the most up to date information to examine in a concise and readable way all the elements that go to make up Britain's defence policy as it goes through the most significant transition since the end of the Cold War in 1991. By analysing the costs of defence, the equipment issues, the personnel, the technical and intelligence back-up for it, and the strategies to employ military forces, this book offers a brief but rich guide to understanding an area of policy that many people find baffling. -- .
