Upon victory in 1945, Britain still dominated the Middle East. But her motives for wanting to dominate this crossroads between Europe, Asia and Africa were changing. Where 'imperial security' - control of the route to India - had once been paramount, now oil was an increasingly important factor. So, too, was prestige. Ironically, the very end of empire made control of the Middle East precious in itself: on it hung Britain's claim to be a great power. Unable to withstand Arab and Jewish nationalism, within a generation the British were gone. But that is not the full story. What ultimately sped Britain on her way was the uncompromising attitude of the United States, which was determined to displace the British in the Middle East. Using newly declassified records and long-forgotten memoirs, including the diaries of a key British spy, James Barr tears up the conventional interpretation of this era in the Middle East, vividly portraying the tensions between London and Washington, and shedding an uncompromising light on the murkier activities of a generation of American and British diehards in the region, from the battle of El Alamein in 1942 to Britain's abandonment of Aden in 1967. Reminding us that the Middle East has always served as the arena for great power conflict, this is the tale of an internecine struggle in which Britain would discover that her most formidable rival was the ally she had assumed would be her closest friend.
