The Individualization of War examines the status of individuals in contemporary armed conflict in three main capacities: as subject to violence but deserving of protection; as liable to harm because of their responsibility for attacks on others; and as agents who can be held accountable for the perpetration of crimes. This book presents a novel conceptualization of the phenomenon of individualization, including how it is both practiced and contested. It then convenes a set of leading thinkers from the fields of moral philosophy, international law, and international relations to further our understanding of not only how individualization is manifest in armed conflict - in theory and in practice - but also how it generates tensions and challenges for today's scholars and practitioners. The collective research on which the book is based integrates the currently segregated scholarship on individualization in different academic disciplines, thereby illuminating the important links between law, morality, and politics that constitute the day-to-day reality for national militaries, international organizations, and humanitarian actors
