This volume provides a timely analysis of global and regional responses to international terrorism. The work assesses the role of the United Nations and its various organs, particularly the General Assembly and the Security Council, and discusses the key legal issues. The second part of the book examines the activity of regional organizations both in their own right as well as their interaction with the UN. The volume concludes with a discussion of whether, to what extent and how the fight against terrorism has encroached upon fundamental rules of international law such as the international protection of human rights or the use of force among states. The volume is the latest in a series drawing on the presentations of high ranking scholars, diplomats and representatives of international organizations. The result is a stimulating and thought-provoking book which will be of interest to researchers and policy-makers alike.
