The document discusses two cases of genocide: the Holocaust and the ongoing genocide in Darfur, Sudan. It notes that both involved the systematic killing and displacement of large groups of civilians by their own governments and armed militias. While the methods and death tolls differed, in both cases extremist groups targeted populations for destruction and needed help from others to carry out mass murder. The document questions what more can be done to seek justice for victims and prevent future genocides when the world fails to intervene to stop such atrocities.
