Che and Fidel were true heroes. No one's perfect but what they did once they went their separate ways was aimed at liberation from systems that are threatening us in the middle-classes. Cuba didn't only send soldiers - they sent eg mechanics, doctors, engineers. A few years ago I read (in a mainstream newspaper) that US Americans were flying to Cuba for eye surgery.
I assume that what will happen when "liberalisation" occurs is that some people will be better off, others worse off, and the poor will end up close to (if not in) despair. The top 1 percent will end up mega-richer. Eventually Cuba will end up like most of the "democratic" countries - basically owned by the Really Big Boys.
But that doesn't take away from the honour owed to Che, Fidel and all the others, unsung.
