While we are on the subject, I have a question. How many people where killed in the Dominican Republic by Trujillo and his US backed government before he was assasinated?
As for Cuba, there have been quite a few, but like MiniD said, its hard to know. Even if you found good data, you'd probably be disapointed. There have been quite a few executions, but most people in Cuba are suprisingly loyal to Fidel, as retarded as that may seem. And the ones who are not, do their best to leave the place in their not so luxurious yatchs.
By the way, Cuba is not as ****ed up as you'd believe. If you dont believe me, take a visit. But that is hard now, as the US government is making it incredibly hard now for students to go to Cuba.
Cuba is a simple place full of simple people. No one is starving, but no one has what we would consider material luxuries. Not even Fidel himself, except that he gets food prepared any time he wants.
The the old school looks of the place reflect its senile leader. For a good insight on present Cuba, watch Oliver's Stone recent documentary "El Comandante". Its interesting, and Fidel is surprisingly open to Oliver.
He does say a blatant lie in one part, when he claims no one has been tortured by his party.
