Fidel Castro’s Cuba has been in the crosshairs of US regime change efforts since the Cuban Revolution in 1958.
After the US-supported failed Bay of Pigs military operation in 1959, the CIA partnered with the Mafia, who had a dominant presence in Havana, to assassinate Castro. The plots were revealed in the mid-1970s by the Church Committee. These ran the gamut from snipers to an exploding cigar.
Following the revolution, Castro and his associates formed an effective police state. Cubans demanding political and civil liberties were denounced as enemies of the state.
