"This path-breaking interdisciplinary project critically analyses the impact of the increased prominence of the individual in the theory and practice of armed conflict. The ‘individualisation of war’, while based on powerful normative and technological developments, places enormous strain on the actors most actively engaged in contexts of conflict: the governments and armed forces of states, international security organisations, and humanitarian agencies.Individualisation has generated new kinds of ‘humanitarian’ wars and peacekeeping missions, as well as precision weapons which enable both the targeted killing of those individuals deemed most liable for acts of war or terror, and the protection of innocent civilians caught up in armed conflict or acts of state suppression. It has also facilitated the injection of human rights law into the law of armed conflict, and a new class of international crimes for which individuals can be held accountable. We hypothesise that efforts to operationalise protection, liability, and accountability are all underpinned by a tension between the newly privileged moral and legal claims of individuals and the more traditional ones of sovereign states. The ethical, legal, and political dilemmas raised by these efforts demonstrate just how contested the process of individualisation remains, and how uncertain is its eventual endpoint.The research of our distinguished inter-disciplinary team will produce two main outcomes: the first integrated conceptual framework for explaining and resolving the dilemmas raised by the individualisation of war; and concrete recommendations for policy actors - both on how to respond to particular ethical, legal, or political challenges and on how to shape the longer term trajectory of individualisation."
