Since the last American troops withdrew from Vietnam during 1975, the strategic value of Africa to the United States has steadily risen. As a result of the renewal of cold-war hostilities between the U.S. and the U.S.S.R. and an escalating series of crises for American foreign policy in the Third World, the African continent is now a principal battlefield for competition involving the United States, Western Europe (particularly France), Cuba, and the Soviet Union. After the end of the Vietnam war, direct American military intervention in Africa was precluded for a short time by legislative restraints – notably the ‘Clark Amendment’ of December 1975 that blocked involvement in Angola – and by the public's reluctance to become entangled in another military commitment overseas, a phenomenon often referred to in Washington as the ‘Vietnam syndrome’. Furthermore, the United States lacked the military capacity to engage in such adventures, having suffered such heavy losses in Indochina and being preoccupied with the creation of a new all-volunteer army. Over the past five years, however, two Administrations in Washington have worked assiduously to ‘cure’ the so-called ‘Vietnam syndrome’ and restore America's military position abroad.
