The Iraq War remains highly controversial, but in all the uncertainty about weapons of mass destruction, the use and misuse of intelligence, it remains an awesome military and political event and a formidable exercise in American power aided by the British army. Throughout the war and beyond it, John Keegan's analysis proved more accurate than any other commentator's, and now he brings his unrivalled knowledge of military history to bear on the war, its conduct and consequences. Written with special access to new sources of information, this book is the most authoritative and challenging account of a war which could both set the pattern for military conflicts in the 21st century and significantly affect the world political order.
