The experience in Somalia exacerbated internal debates around the role of American military power in the Post–Cold War era. In a victory for those who favored non-intervention, Clinton placed new limits on the deployment of his troops, especially as part of U.N. peacekeeping missions. In April 1994, the Hutu of Rwanda engaged in a genocide against the minority Tutsi, killing 800,000 people in a three-month span. The UN sent a small force to provide aid, but the U.S., with no strategic or economic interest in the country, did not intervene. Clinton would later describe the non-intervention in Rwanda as the worst mistake of his administration.
