<P> U.S. President Dwight D. Eisenhower officially recognized the new Cuban government after the 1959 Cuban Revolution which had overthrown the Batista government, but relations between the two governments deteriorated rapidly . Within days Earl E.T. Smith, U.S. Ambassador to Cuba, was replaced by Philip Bonsal . The U.S. government became increasingly concerned by Cuba's agrarian reforms and the nationalization of industries owned by U.S. citizens . Between 15 and 26 April 1959, Fidel Castro and a delegation of representatives visited the U.S. as guests of the Press Club . This visit was perceived by many as a charm offensive on the part of Castro and his recently initiated government, and his visit included laying a wreath at the Lincoln memorial . After a meeting between Castro and Vice-President Richard Nixon, where Castro outlined his reform plans for Cuba, the U.S. began to impose gradual trade restrictions on the island . On 4 September 1959, Ambassador Bonsal met with Cuban Premier Fidel Castro to express "serious concern at the treatment being given to American private interests in Cuba both agriculture and utilities ." </P> <P> The Escambray rebellion was a six - year rebellion (1959--1965) in the Escambray Mountains by a group of insurgents who opposed the Cuban government led by Fidel Castro . The rebelling group of insurgents was a mix of former Batista soldiers, local farmers, and former allied guerrillas who had fought alongside Castro against Batista during the Cuban Revolution . As state intervention and take - over of privately owned businesses continued, trade restrictions on Cuba increased . The U.S. stopped buying Cuban sugar and refused to supply its former trading partner with much needed oil, with a devastating effect on the island's economy, leading to Cuba turning to their newfound trading partner the Soviet Union for petroleum . In March 1960, tensions increased when the freighter La Coubre exploded in Havana Harbor, killing over 75 people . Fidel Castro blamed the United States and compared the incident to the sinking of the Maine, though admitting he could provide no evidence for his accusation . That same month, President Eisenhower quietly authorized the Central Intelligence Agency (CIA) to organize, train, and equip Cuban refugees as a guerrilla force to overthrow Castro . </P> <P> Each time the Cuban government nationalized American citizens properties, the American government took countermeasures, resulting in the prohibition of all exports to Cuba on 19 October 1960 . Consequently, Cuba began to consolidate trade relations with the USSR, leading the U.S. to break off all remaining official diplomatic relations . Later that year, U.S. diplomats Edwin L. Sweet and William G. Friedman were arrested and expelled from the island having been charged with "encouraging terrorist acts, granting asylum, financing subversive publications and smuggling weapons". On 3 January 1961 the U.S. withdrew diplomatic recognition of the Cuban government and closed the embassy in Havana . </P> <P> Presidential candidate John F. Kennedy believed that Eisenhower's policy toward Cuba had been mistaken . He criticized what he saw as use of the U.S. government influence to advance the interest and increase the profits of private U.S. companies instead of helping Cuba to achieve economic progress, saying that Americans dominated the island's economy and had given support to one of the bloodiest and most repressive dictatorships in the history of Latin America . "We let Batista put the U.S. on the side of tyranny, and we did nothing to convince the people of Cuba and Latin America that we wanted to be on the side of freedom". </P>
