In April 1994, the small central-African nation of Rwanda was host to one of the most brutal genocides in 20th-century history. Spurred on by the racist propaganda of a rogue political party, extremists in the majority Hutu ethnic group slaughtered 800,000 members of the minority Tutsi ethnic group in the span of 100 days (and mostly by machete). Largely misinterpreting the genocide as the result of a centuries-old tribal rivalry, the rest of the world stood idly by, both unable to understand the conflict and unwilling to commit to intervention. This episode of PBS' FRONTLINE series revisits the still-wounded nation on the 10th anniversary of the genocide and explores the various political failures that allowed such a tragedy to take place, interviewing Rwandan government officials, foreign diplomats, UN Secretary-Generals Kofi Annan and Boutros Boutros-Ghali, former Secretary of State Madeleine Albright, and, most hauntingly, both Tutsi survivors and their Hutu assassins.
