Fidel Castro was a communist despot. He is responsible for the suffering of the cuban people. He ruled over Cuba in total denial of his country's problems. Its because of him that hundreds of cubans make it to Florida's shores.
I don't think he will be back to ruling Cuba again. I think that his illness is caused by over 40 years of stress and hypertension. Ruling a country takes a lot from a man. I have my doubts as to whether he will make it past 2007. Most people his age don't have it good. They cannot get back to ruling a country. Pretty soon, the Cuban immigrant community here will be celebrating Castro's passing. After he passes, all that leaves is Raoul.
It is interesting to think of Cuba. I think they would be worse off now if the revolutionaries hadn't taken over the country and held it. He did introduce a number of good changes, like producing the best medical system in Latin or South America - -with state provided health care at that. They are the healthiest people in the region.
However, I think they would probably be still better off if Castro had voluntarily left power and introduced democracy as he promised he would way back when.
When Castro dies and Raoul takes power, what then? Raul is also elderly. Who comes after him?
