In many ways, these are timeless questions. But they should be revisited in light of changing circumstances in the twenty-first century. The post-Cold War, post-9/11 world is one of contested and fragmented sovereignty: contested because the norm of territorial integrity has shed some of its absolute nature, fragmented because some states do not control all of their territory and cannot defeat violent groups operating within their borders. Humanitarian intervention, preventive war, and just war are all framing mechanisms aimed at convincing domestic and international audiences to go to war—or not, as well as to decide who is justified in legally and ethically killing. The international group of scholars assembled in this book critically examine these frameworks to ask if they are flawed, and if so, how they can be improved. Finally, the volume contemplates what all the killing and dying is for if victory ultimately proves elusive.
