Castro's role in intensifying American antagonism.

Building up to the Cuban Missile Crisis, aggression occurred between the USA and Cuba for many reasons. Cuba had been in the hands of Fulgencio Batista since 1933. Batista was a military dictator and his corrupt rule caused popular discontent. Fidel Castro came into power January 1st 1959, after a brief struggle with Batista, with the help of Ernesto "Che" Guevara and nine other rebels. Castro was a brilliant propagandist and a very charismatic person. The incidents which happened between 1959 and 1961 built up tension and resulted in strong animosity.

Economically, Cuba had always been dependent on the United States. The US was exploiting them, owning most of Cuban industry, transportation, electricity production and telephone lines. 80% of Cuba's export revenue was from producing and selling sugar. Most of this sugar was grown on plantations owned by the United States and then sent to the USA. Under Batista's rule, the United States was allowed to continue with their actions but when Fidel Castro came into power in 1959, he formed a new government. Castro wanted to make Cuba an independent country, free from US control and exploitation. He nationalized industry, impounded all foreign-owned property, and collectivized agriculture. This did not please the US government. President Dwight Eisenhower decided to stop trading arms with Cuba and eventually refused to purchase Cuban sugar in July of 1960. Castro looked to the Soviet Union for assistance. The USSR saw this as an opportunity and took advantage of the situation. The Soviets would buy Cuban sugar and in return, they would send oil, machines and money. In response to the US's action, Castro nationalized most US-owned factories and plantations. US-owned oil refineries were nationalized when they refused to take Soviet oil. Eventually, Castro severed all economic and political ties to the United States.

Secondly, political affairs added to the antagonism between the USA and Cuba. After Castro came into power, he established a totalitarian government which benefited the working class at the expense of the middle class. Castro arrested, imprisoned and executed many of Batista's supporters who had been responsible for the repression of Cuba. This heightened tension because many of the people executed were in fact allies to the United States. Most social and political opposition between the United States and Cuba happened because of the fact that Cuba had become communist with the aid of the USSR. At this time, to the United States, communism was seen as the enemy. Cuba was essentially a puppet state of the US. As it wiggled out of their grasp, they needed to act. The United States needed to show the world they were still a super power. Destroying Castro became a priority.

Militarily, the Bay of Pigs invasion was the "straw which broke the camels back". The Bay of Pigs invasion was a very unsuccessful invasion of Cuba issued by the new US president John F. Kennedy. The plan was suggested by Richard Nixon, Eisenhower's Vice president. The CIA had been scheming different strategies to take Castro out of power but none had been successful. Towards the end of Eisenhower's term, the CIA came up with a plan titled "A Program of Covert Action Against the Castro Regime" on March 17th 1960. The Bay of Pigs invasion started on April 17th when six ships sailed from Nicaragua. Roughly 1,500 Cuban exiles landed in the Bay of Pigs, Bahi a de Cochinos, with the sole purpose of ousting the Communist regime present under Castro. These exiles were trained by the CIA and supplied with U.S. arms but they barely made it past the beaches. Most exiles were captured and killed by the Cuban army. 1,189 men were captured and each sentenced to thirty years in prison. After months of interrogation and negotiation, in December of 1962, Cuba traded 1,112 captured rebels for fifty-three million US dollars in food and medicine. Castro saw the Bay of Pigs as confirmation that the USA was working to overthrow his government. The United States was terrified and embarrassed that Cuba, only 90 miles from the shores of Florida, a country in American's sphere of influence, had become communist.

By the end of the Bay of Pigs invasion, both the United States and Cuba were aware that the hostility and aggression towards one another would not go away. Pressure only increased as the US struggled to fight communism.
