The main theme of this volume of theYearbook of International Humanitarian Lawis weapons law. In several chapters, how International Humanitarian Law (IHL) copes with old and new weapons as well as political developments in regard to military technology is discussed, while in two chapters the significance of non- or less-lethal weapons in peace-keeping and law enforcement operations as well as the legality of lethal autonomous weapons systems under IHL are analysed. Moreover, the volume describes the current status of nuclear deterrence under international law. Another layer is added by examining how IHL influences the programming of automatic target recognition systems using artificial intelligence. The second section of the book contains a historic perspective on the roots of IHL in Europe, which can be traced back to the ninth century, as well as aYear in Reviewdescribing the most important events and legal developments in the area of IHL that took place in 2018. TheYearbook of International Humanitarian Lawis 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, theYearbook of International Humanitarian Lawbridges 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. | Yearbook Of International Humanitarian Law Volume 21 (2018) by Terry D.
