For years following the triumph of the Cuban revolution in 1959, a nightmare scenario haunted American leaders: Fidel Castro, having overthrown one government closely allied to the United States, would succeed in sparking radical movements elsewhere in the Western Hemisphere to do the same. By the early 1960s, the Kennedy administration believed that Havana was working hard at it. The Central Intelligence Agency reported in early 1963 that the Cuban government was training as many as 1,500 revolutionaries from across Latin America in techniques of political subversion and guerrilla warfare-lessons they were to take back to their home countries to ignite rebellion. Castro and his legendary collaborator, Che Guevara, seemed to take interest in the effort. The two men frequently appeared before the foreign trainees to give personal pep talks, the CIA noted.' American officials could have rested easy. Over the remainder of the Cold War, the Cuban government scored few successes in its bid to challenge U.S. hegemony in Latin America. Another failed to materialize, not least because the Castro government shied away from actions that would seriously challenge Washington. The threat of U.S. retaliation against Cuba, even an invasion of the island, was simply too great to risk anything forceful. During the 1960s, fewer than forty Cubans participated in guerrilla struggles elsewhere in Latin America, and Havana showed little enthusiasm about sending weapons to support rebel movements. When Cuba did act, the results were disastrous. Most famously, U.S.-backed paramilitary forces crushed Guevara's 1967 foray into Bolivia, killing him and demolishing his vision of spreading grassroots revolution across the continent. The story of Cuban efforts to promote revolution abroad does not, however, end in the Bolivian mountains. As Piero Gleijeses makes clear in his stunning book, Conflicting Missions: Havana, Washington, and Africa, 19591976, it was Africa, not Latin America, where Castro's Cuba acted boldly on its dream of supporting leftist liberation struggles against the United States
