Recognizing that Castro and his government were becoming increasingly hostile and openly opposed to the United States, Eisenhower directed the CIA to begin preparations of invading Cuba and overthrow the Castro regime. Richard M. Bissell Jr. was charged with overseeing plans for the Bay of Pigs Invasion.
The United States' Central Intelligence Agency (CIA) made numerous unsuccessful attempts to assassinate Cuban leader Fidel Castro. There were also attempts by Cuban exiles, sometimes in cooperation with the CIA. The 1975 Church Committee claimed eight proven CIA assassination attempts between 1960 and 1965.
