Did Machete-Wielding Hutus Commit Genocide or Just 'Acts of Genocide'?
One of the issues administration officials debated behind the scenes was whether it was best to avoid using the word genocide to describe what was happening, as that might increase legal and political pressure to act. Documents disclosed last week by the National Security Archive show some of that debate. On May 21, 1994, Secretary of State Warren Christopher agreed to allow department officials to say that "acts of genocide have occurred," and on June 10, he finally flatly called it genocide. Between April 6, when the killing began, and July 4, when the Tutsi rebels took over the capital city of Kigali, an estimated 800,000 people were slaughtered.
