President George H. W. Bush had sent American troops on a humanitarian mission to Somalia in December 1992. 18 of them were killed and 80 wounded in a botched raid, ordered by President Clinton, in October 1993. Public opinion, and most elite opinion, swung heavily against foreign interventions that risked the lives of American soldiers when American national interests were not directly involved. That meant humanitarian missions were problematic. Clinton agreed, and sent ground troops only once, to Haiti, where none were hurt. He sent the Air Force to do massive bombing in the former Yugoslavia, but no American crewmen were lost. The major trouble spots during his two terms were in Africa (Somalia and Rwanda) and Eastern Europe (Bosnia, Herzegovina, and Kosovo in the former Yugoslavia). Clinton also tried to resolve long-running conflicts in Northern Ireland, and the Middle East, particularly the Israeli–Palestinian conflict.
