Yoram Dinstein's seminal textbook is an essential guide to the legal issues of war and peace, armed attack, self-defence and enforcement measures taken under the aegis of the Security Council. This third edition incorporates new material on the Kosovo air campaign, 'humanitarian intervention', recent resolutions adopted by the Security Council, the latest pronouncements of the International Court of Justice and the International Criminal Tribunal for the former Yugoslavia. Also discussed are new treaties including the 1998 Rome Statute on the International Criminal Court and current studies of the International Law Commission. In addition, supplementary sections consider, for example, enforcement action carried out by regional organizations under the authority of the Security Council. War, Aggression and Self-Defence remains a comprehensive and highly readable introduction to the legal issues surrounding war and self-defence, and continues to provide an indispensable tool for students and practitioners of international law, international relations and military studies.
