This book explores the acquisitive thinking which, from the autumn of 1914, nourished the Mesopotamian Expedition and examines the political issues, international and imperial, delegated to a War Cabinet committee under Curzon. The motives of Curzon and others in attempting to obtain a privileged political position in the Hejaz are studied in the context of inter-Allied suspicions and Turkish intrigues in the Arabian Peninsula. Debate on the future of Mesopotamia provided an outlet for differences between those who justified British gains on the basis of military conquests and those who realised that expansion must be reconciled with broader international trends. By 1918, Britain was developing strategic priorities in the Caucasus. Fisher analyses Turco-German aims in 1918 and challenges the notion of their leading, straightforwardly, to the zenith of British imperialism in the region. This is a penetrating study of war imperialism, when statesmen contemplated strong measures of control in several areas of the Middle East.
