’Luke Middup has produced a closely argued analysis of the so-called Powell Doctrine. He discusses its intellectual origins and examines each of its five principles and how they have been deployed or ignored in five chapters of case-studies. The book ends with two chapters providing an interesting analysis of how the principles have been applied or not as the case may be in Iraq and Afghanistan.’ Alan Dobson, St Andrews University, UK ’Luke Middup has done a fine academic service by providing a clear-eyed interpretation of both the application and non-application of the Powell Doctrine. Drawing upon key case studies of the deployment of American military force, Dr Middup shows the relevance and wisdom of the Doctrine for policy-makers in assessing the nature and limits of that force’s utility.’ Nigel Bowles, University of Oxford, UK
