After just 100 hours of ground combat, and with all of Kuwait and much of southern Iraq under coalition control, US President George H. W. Bush ordered a cease-fire and negotiations began resulting in an agreement for cessation of hostilities. Some US politicians were disappointed by this move, believing Bush should have pressed on to Baghdad and removed Hussein from power; there is little doubt that coalition forces could have accomplished this if they had desired. Still, the political ramifications of removing Hussein would have broadened the scope of the conflict greatly, and many coalition nations refused to participate in such an action, believing it would create a power vacuum and destabilize the region.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): Who ordered the cease-fire that effectively ended hostilities?
US President George H. W. Bush
