I was not aware that Castro "ruled by terror."

According to Castro's own estimates, at one point there were as many as 15,000 political prisoners in Cuba. One of the darkest periods of the repression occurred in 1963 when Castro approved "Operation P," named because of a black "P" (for pimps, prostitutes, pederasts) emblazoned on the uniforms of those arrested. The operation saw Castro's newly formed secret police sweep through Havana targeting homosexuals, religious believers, and "deviants"—often no more than men with long hair and blue jeans. Those rounded up were placed in UMAPs (Military Units to Help Production), a euphemism for concentration camps, and forced to do hard labor. According to the poet Armando Valladares, imprisoned by Castro in 1960, "there have been few examples of repression of homosexuals in history as virulent as in Cuba."

These are just a few examples, there are many more if you care to look.
