Genocide is the deliberate murder of a racial, ethnic, tribal, national, or religious group. It is one of the world’s most horrifying crimes, yet the role that the international community should play when a genocide is underway remains unclear. Are other nations obligated to step in when a genocide is taking place? If so, what signals that it’s time to step in? This book looks back at some of the most reprehensible acts of genocide in human history to gain a better understanding of what interventions have taken place in the past, and to what extent they have helped. Sidebars, full-color photographs, and a glossary help readers gain a deeper understanding of the many sides of this complex issue.
