Totalitarian regimes usually have a number of expat groups operating outside the country who are prone to over-exaggerating stories about the imminent collapse of the regime. Ask yourself how many stories we've seen in the past years claiming that there are massive protests all over Iran, that the mullahs are about to fall, that there is about to be a huge revolution, etc.--only to have nothing happen. Same is probably true of Cuba. I'm not saying there is no truth to it, just that in my experience people posting these accounts usually have such a strong desire to see the regime collapse that they overdramatize the situation.
I don't believe anything until I can get some confirmation from another source. Sorry. The only thing I certainly know is that dissidents have been "detained" and there are many folk upset about this. Still more folk are upset about the economy, etc. Surely, if this event were of any significance, someone would be reporting about the goings on.....
I know. I think there will even be a castro leading cuba long after this one is dead.
The only way to end this crapstate is to decide to end that regime.
soon, China will be in the mix and that ain't good.
