This paper explores the concept of “the Responsibility to Protect” (R2P), an outcome of the 2005 World Summit which entails that the international community has a moral duty to intervene in the domestic affairs of sovereign states in cases involving war crimes, crimes against humanity, ethnic cleansing, or genocide. The author illustrates the historical legacy of the R2P, covering how early legal philosophers justified the intervention of European powers through theories such as just war, intervention in the name of humanity, and humanitarian intervention, before exploring whether R2P represents a violation of well-established principles of international law: the sovereignty of states and non-intervention in their affairs and the non-use of force in international affairs. The paper concludes that R2P does not provide for the use of force in a manner that does not already exist in the UN Charter.
