America put Cuba under a state of Siege for fifty years

Again, no matter how often you keep repeating it there was no siege. You are just lying to justify totalitarian oppression.

Whatever did and didn't happen in Cuba was caused by the circumstances imposed on it from outside, not from internal tyranny.

Again I quote from Solidarity: (an independent socialist organization dedicated to forming a broad regrouping of the U.S. left.)

"despite the strenuous efforts of the U.S. government, Cuba has not been isolated from most of the rest of the globe. The main causes of Cuba's poverty must surely be domestic."
