Yep. Would it likewise surprise you to learn that the Pinochet government, which is described in similar ways, killed (at the high end of the estimates; the officially accepted ones are 10-20% lower) about 3200 people and "disappeared" about 1000, over the course of 17 years? Also, about 30,000 tortured, though; I have not seen claims of this for Castro's Cuba. All this out of a population of 10-13 million. It sure surprised me when I looked up the numbers.

I'm not condoning the things either government (Pinochet's or Castro's) did, but they are both nowhere close to being "drenched in blood" the way Stalin's or Pol Pot's or Mao's governments were.
