Although United Nations Peacekeeping Operations (UNPKO) are said to protect humanitarian rights, peacekeepers are found to commit sexual assault, war crimes, and gross negligence. International legal immunities exempt peacekeepers and the UN from criminal liability and civil litigation. Whereas the literature on peacekeeper abuses conceptualizes the problem to be one of implementation of immunities, this thesis contends that such views are uncritical towards peacekeeping, immunity itself, and international society that organizes UNPKO. I theorize that the legal structures permitting such abuses (e.g. the UN Charter) render individuals expendable and hence objectified for the sake of international order. The argument presents a case study of the Srebrenica Massacre and ensuing legal cases to illustrate how immunities objectify individuals. Drawing on Agamben's theory of homo sacer, I introduce the term civis sacer to describe individuals excluded from international law with UNPKO immunities that objectifies them for the sake of maintaining international order. / Graduate / 0616
