Eisenhower's+Policy+Toward+Castro

The United States officially recognized Cuba's new government six days after Castro took power, though tensions rose quickly as Cuba moved to nationalize factories and plantations, which were primarily owned by American companies. At first, the United States was supportive of Castro but once Castro began to make an alliance with the Soviet Union, the United States' top enemy, relations quickly deteriorated. Eisenhower ordered the CIA to plan a covert operation to overthrow Castro. He also, in the summer of 1959, ordered US oil refineries located in Cuba to not refine Soviet crude oil. He then cancelled the Cuban sugar quota for the rest of the year. This resulted in Castro nationalizing all US owned businesses. A few days before the inauguration of John F. Kennedy, the US ended all diplomatic relations with Cuba.
