There's definitely a kind of insanity at work here. Castro's saying, "If you try to depose me, I'll release this stuff and I'll die, lots of my people will die, and lots of your people will die, too. Is it worth it, Yankee?"
Meantime, he's free to release it anytime he sees fit, and without provocation, just because he's a vicious SOB who's getting old and depressed that his reign as supreme leader is coming to an end.
We've gotta remove him at the first opportunity, imho.
While I agree that the leaders themselves, Castro and Saddam among others, need to be removed, because of the Clinton Legacy, we have few (if any) operatives in position for an inside job. It takes time to maneuver into such positions.
