"This book will consider a rapidly emerging guiding general principle in international relations and, arguably, in international law: the Responsibility to Protect. This principle is a solution proposed to a key preoccupation in both international relations and international law scholarship: how the international community is to respond to mass atrocities within sovereign States. There are three facets to this responsibility; the responsibility to prevent; the responsibility to react, and the responsibility to rebuild. This doctrine will be analysed in light of the parallel development of customary and treaty international legal obligations imposing responsibilities on sovereign states to the international community in key international law fields such as international human rights law, international criminal law and international environmental law" (publisher's website).
