There are countless of well-documented examples of the American empire sponsoring terrorist attacks, sabotage and assassinations against Cuba. To this day the American empire upholds an illegal an unprovoked blockade of the island as well as occupying the land on which the Guantanamo naval base and torture black site is placed.

Before the revolution, America ran Cuba as a colony, leeching off the hard work of Cubans. If anything, the history of American relations with Cuba has been one of profound violence.

But okay, most of the times they made sure to put in a middle-man to do the actual dirty work which absolves them of all sin I guess.
