Which incident in Somalia caused President Clinton to withdraw U. S. troops from the country?

The United States sent food aid via Operation Provide Comfort starting in August 1992 ... In December 1992, the United States began Operation Restore Hope. President George H. W. Bush authorized the dispatch of U. S. troops to Somalia to assist with famine relief as part of the larger United Nations effort.

Actually, the most significant o challenges came on October 3, 1993. Aideed's forces shot down two Black Hawk helicopters in a battle which lead to the deaths of 18 U. S. soldiers and hundreds of Somalis. The deaths turned the tide of public opinion in the United States. President Bill Clinton pulled U. S. troops out of combat four days later, and all U. S. troops left the country in March 1994. The United Nations withdrew from Somalia in March 1995. Fighting continued in the country. At the same time the Somalia crisis was unfolding, President Clinton ordered the national security bureaucracy to consider how and when the United States should become involved in peacekeeping operations. The resulting document was Presidential Decision Directive 25, issued on May 3, 1994. The Directive outlined a series of factors which the national security bureaucracy must consider before involving the United States in peacekeeping: eight factors which must be weighed before deciding in favor of peacekeeping in the United Nations, and nine additional factors before becoming involved in a Chapter VII action.
