Since the fall of the Berlin Wall, American military forces have been used to remove the ruler of Panama, to drive the Iraqi army out of Kuwait and later to deter its return, to alleviate a famine in Somalia, to remove a military junta from Haiti and restore the elected president to power, to compel warring ethnic factions in Bosnia to stop fighting and then to enforce the resulting truce until elections could be held, and to deter a threat from China against Taiwan, among other interventions. At the same time, American forces have been stationed in Korea to deter an attack from the north and in the Persian Gulf to deter aggressive actions by either Iran or Iraq.
