'This book is obligatory reading for anyone wishing to obtain a deeper understanding of not just the challenges facing the NPT, but also wider challenges to nuclear security and stability that appear likely to dominate the twenty-first century. It will undoubtedly be of use to both scholars and policy-makers, and indeed to anyone with an interest in ensuring a stable and peaceful global order, and of course, to those interested in the much publicized renewal of the global nuclear zero agenda.' - Andrew Futter, International Affairs, Volume 88, 4, July 2012
