The basic facts of the genocide that engulfed Rwanda a decade ago are well known (see "Healing Genocide," CT April 2004, p. 76). Hutu militias, soldiers, and ordinary citizens used machetes and guns to slaughter 800,000 Tutsis and moderate Hutus, in what The Atlantic called "the most efficient killing spree of the 20th century." With an average of 8,000 people dying daily, the United States deplorably led an effort to remove U.N. peacekeepers from Rwanda, refused to jam radio broadcasts that incited the mayhem, and would not use the term genocide to describe the carnage, afraid of its obligation to act.
