The mass killings in Rwanda in 1994 shocked the world but the international response was ineffective. The end of the Cold War had created a moral climate supportive of humanitarian intervention and enforcement of the Genocide Convention, but it had not produced adequate legal and structural mechanisms to carry out such action. The book examines the failures of the United Nations, the Organization of African Unity, regional states and major world powers either to prevent or terminate the genocide and draws lessons for intervention in future.
