Scholarship on NATO is often preoccupied with key episodes in the development of the organisation and so, for the most part, has remained inattentive to theory.

This book addresses that gap in the literature. It provides a comprehensive analysis of NATO through a range of theoretical perspectives that includes realism, liberalism and constructivism, and lesser-known approaches centred on learning, public goods, securitisation and risk. Focusing on NATO's post-Cold War development, it considers the conceptualisation, purpose and future of the Alliance.

This book will be of interest to students and scholars of international organisation, international relations, security and European Politics.

"Theorising NATO is a useful exercise, worth reading for students and scholars of both NATO and IR theory. For NATO specialists, Webber and Hyde-Price's book provides new answers to old questions - especially the ones connected to NATO's persistence in the post-Cold War era. Both Flockhart's constructivist analysis and the contribution on securitisation by Gabi Schlag (Otto von Guericke University of Magdeburg) offer answers to this question that are not superficial. For IR theory enthusiasts, Theorising NATO attests concretely to the importance of theory in International Relations and provides a practical and powerful demonstration that multiple theoretical points of view can coexist and reinforce one another harmoniously, if considered with sufficient analytical eclecticism."
