This book provides a descriptive and analytical narrative of the evolution of US foreign policy towards Iraq at the supra-national (global), national (Arab Iraq) and sub-national (Iraqi Kurdistan) levels. The book is unique in that it presents a sophisticated insight into the two major components of US Iraq policy. To achieve this, it addresses US foreign policy towards both Arab Iraq and an entirely original analysis on US policy towards the Iraqi Kurds as components of a larger US Iraq policy, dictated by the supreme US Grand Strategy. The book also examines whether US foreign policy towards Iraq has been one of continuity or change - a dimension that has not been illustrated in any other publication. The book deals intelligently and at great length with the events surrounding US Iraq policy in three distinct phases, going back to, 1979 with regard to Arab Iraq, and 1961 in respect to the Kurdish liberation movement, covering all subsequent US administrations including the Obama presidency. It provides a thorough examination of US interests in Iraq and reasons for the 2003 invasion and its aftermath. It also engages with the intellectual roots of US foreign policy, presenting an intricate reaction of views, objectives and agendas. This work will be of interest to students and scholars of Middle East studies, US Foreign Policy and Security studies.
