When Castro really does die before they ever announce it they will call in the National Guard.
Miami in effect will be closed.
Even without confirmation from Cuban officials our own satellites would pick up a strong military presence on the island and most likely their the phone communications from Cuba to the US would conveniently suffer a glitch.
I was a senior in high school when Cubans began to flee into Miami. Before that, a young priest and his wife had served in Cuba and knew of Castro. At that time we were given the impression he was a hero fighting a corrupt Batista. I was working after school at our rec center. We began to get a few kids who had just come over. One mother told me about coming over with just the clothes on their backs. She had sewn in every valuable piece of jewelry she could to the clothes. These were to sell so they could live.
As time went on, the refugees began to have children who became Americanized and then they had children. Now we have second generation Cuban-Americans. I point to one very successful Cuban I know who is now a partner in a very prestigious accounting firm. I know he would never return to Cuba.
When Castro does die, I know Miami will be celebrating. I also believe Anglos would celebrate with the Cubans also.
I also remember the Mariel boatlift time. Chaos. The rise of the cocaine cowboys and crime.
What will Cubans do after the celebration dies down? I'd bet a number of die-hards will try to storm over to Cuba, maybe in mass numbers.
Looking back at recent events, I would bet that Castro and his brother have been negotiating heavily with Hugo Chavez of Venezuela. Something may be up between them. Chavez hates the US and may move troops into Cuba to keep ex-patriates out. I couldn't blame those who fled Cuba for wanting to have their homes back. Think about having troops coming into your town and home and demanding you leave.
I will be anxious to see what happens when he truly dies and we know all about it.
