The US couldn't possibly have had anything to do with the bombing, given the auspicious beginning between Castro's government and US relations:

"January [1960] Cuba expropriates 70,000 acres of property owned by U.S. sugar companies, including 35,000 acres of pasture and forests owned by United Fruit Company in Oriente province. United Fruit owns approximately 235,000 acres in addition to this. By confronting United Fruit (later United Brands and Chiquita Brands), Cuba is antagonizing a powerful organization that played a major role in the 1954 overthrow of the elected Arbenz Government in Guatemala. Secretary of State John Foster Dulles has been both a stockholder and a longtime legal adviser for the company, including preparation of contracts in 1930 and 1936 with the Ubico dictatorship in Guatemala; his brother Allen W. Dulles, director of the CIA, was once president of the company; UN Ambassador Henry Cabot Lodge has been a member of its board of directors; Walter Bedell Smith, head of the CIA before Dulles, became president of United Fruit after the overthrow of Arbenz.

"August The CIA takes steps to recruit members of organized crime for help in assassinating Prime Minister Castro. According to testimony by Colonel Sheffield Edwards on May 30, 1975, to the Senate Select Intelligence Committee on Assassinations, Richard Mervin Bissell Jr., former Yale professor turned CIA chief of covert operations, asks Edwards, director of the CIA's Office of Security, to locate someone who could assassinate Castro. Bissell confirms this in his own 1975 testimony."

Oh, yeah, and, of course, all those other things we didn't do to Cuba.

If Bolton gets rejected they may want him for that UN post.Or put his mug on the twenty, replacing that other great terrorist.
