The Yearbook of International Humanitarian Law is the world's only annual publication devoted to the study of the laws governing armed conflict. It provides a truly international forum for high-quality, peer-reviewed academic articles focusing on this crucial branch of international law. Distinguished by contemporary relevance, the Yearbook of International Humanitarian Law bridges the gap between theory and practice and serves as a useful reference tool for scholars, practitioners, military personnel, civil servants, diplomats, human rights workers and students.   The present volume contains articles on such timely topics as the Arab Spring, the duty to investigate humanitarian law violations, the US position on Additional Protocol I, NATO’s Libyan operations and the killing of Osama bin Laden. It also features a 10 year retrospective forum in which distinguished academics and practitioners reflect on the significance of the “9/11” attacks for international humanitarian law. A comprehensive bibliography of publications in the field is included in the volume.
