The CIA's covert programme to assassinate Cuban leader Fidel Castro — encompassing Operation Mongoose and related activities — is among the best-documented cases of state-sponsored political assassination planning in Cold War history. The Church Committee (1975) documented at least eight distinct plots between 1960 and 1965. Methods proposed or attempted included poisoned cigars, an exploding seashell, a contaminated diving suit, and a poison-pen device. The CIA partnered with Mafia figures including Johnny Roselli and Sam Giancana through intermediary Robert Maheu. Marita Lorenz attempted a botched poisoned-pill attack. Castro survived all attempts and died of natural causes in 2016.
