'An excellent book which has already stimulated me to rethink some aspects of a field in which I have worked for many years. I can recommend it to both experts and students.' - Robert Jervis, Columbia University 'A major theoretical contribution on one of the core concepts in international politics. It is filled with smart insights and treats other approaches in a fair and sophisticated way. No future scholar will be able to write about the security dilemma without engaging this cutting-edge work.' - John J. Mearsheimer, University of Chicago, USA 'Learned and incisive, yet also impressively clear and balanced, this long-anticipated book has been well worth the wait. Booth and Wheeler put the concept of the security dilemma at the centre of how we should think about international relations knitting the whole subject together so well around their core theme that this could easily be used as a main teaching textbook in IR. It is hard to think of a better written or more stimulating (re)introduction to the subject than this'. - Barry Buzan, London School of Economics and Political Science, UK 'A landmark work of great intellectual depth and normative contemplation. This book speaks to theorists, policymakers, and global citizens as they grapple with the most daunting issues of our time.' - Geoffrey Wiseman, University of Southern California, USA, and formerly of UN Secretary-General's Office '[I]ncisive, well research and thought-provoking ... Booth and Wheeler falls into the "must read" category for anyone seeking an in-depth understanding of the security dilema.' - Andrew Liaropoulos, The International Spectator
