<P> As UNITAF's mandate was to protect the delivery of food and other humanitarian aid, the operation was regarded as a success . United Nations Secretary - General Boutros Boutros - Ghali determined that the presence of UNITAF troops had a "positive impact on the security situation in Somalia and on the effective delivery of humanitarian assistance ." An estimated 100,000 lives were saved as a result of outside assistance . </P> <P> One day prior to the signing of the Addis Ababa Agreement, the United Nations Security Council passed Resolution 814, which marked the transfer of power from UNITAF to UNOSOM II, a United Nations led force . The major change in policy that the transition from UNITAF to UNOSOM II entailed is that the new mandate included the responsibility of nation - building on the multinational force . On 3 May 1993, UNOSOM II officially assumed command, and on 4 May 1993 it assumed responsibility for the operations . </P> <P> Operation Continue Hope provided support of UNOSOM II to establish a secure environment for humanitarian relief operations by providing personnel, logistical, communications, intelligence support, a quick reaction force, and other elements as required . Over 60 Army aircraft and approximately 1,000 aviation personnel operated in Somalia from 1992 to 1994 . </P> <P> Crucially however, no disarmament of the rivaling factions within Somalia was undertaken . This meant that the situation stayed stable only for the time UNITAF's overwhelming presence was deterring the fighting . Therefore, the mandate to create a "secure environment" was not achieved in a durable fashion . </P>

Where did the us send a humanitarian force from 1992 to 1994
