U.S. 1960s and 1970s
In the United States, he befriended
Mafia bosses such as
Santo Trafficante, as well as union leader
Jimmy Hoffa. He established the
30th of November organization, with the purpose of killing Castro. Masferrer was known for mistreating Cubans residing in
Florida, extorting money from them for what he said would be "to help Cuba". On 26 September 1960, Masferrer sent an expedition of four boats to Cuba. One boat reached the island, three Americans: Allan D. Thompson, Anthony Zarba and Robert O. Fuller were caught and eventually executed. In December, 1960, the
Miami Herald, reported that Masferrer was leading a group of 53 people, undertaking training for assassination at a ranch owned by multi-millionaire
Howard Hughes. In the early 1960s, Masferrer was associated with
El Tiempo, a Spanish-language newspaper, edited by S. Ross, in
New York City. In 1961, Masferrer met with President
John F. Kennedy, to discuss Castro and the situation in Cuba. But Kennedy disliked Masferrer's radical and fanatical personality, and the two did not have any publicly known conversation after that. In 1967, Masferrer plotted and accumulated weapons to invade
Haiti and overthrow
François Duvalier so as to have a base, free of U.S. law, to attack the Castro government which had foiled direct attempts to land (Project Nassau or Operation Istanbul). Masferrer served two years of a four-year sentence for two counts of violating the
Neutrality Act of 1794 in the U.S. (1970–72). Five of his accomplices received lesser sentences. He owned a security agency in Miami, and published the weekly Libertad (Freedom). The Castro government had sentenced him to death in 1959. Masferrer was killed by a
car bomb (specifically dynamite) on 31 October 1975. Left-wing sources say that the assassination was allegedly ordered by the anti-Castro militant Guillermo Novo, who was soon to be associated with the US-backed
Coordination of United Revolutionary Organizations and the
assassination of Orlando Letelier by car bomb in 1976. ==Notes==
