Walker Centennial Chair in Law 'A provocative case for extending the concept of self-defence in international relations to include pre-emptive armed action. Based on a reasoned argument about the changed global security situation, it deserves attention even those who are sceptical of Western military action.' -- Martin Shaw, University of Sussex
