Castro Quits

Well, how about that.
He’s been sitting in the top job almost 50 years. Smart money was on him staying there until he died, I would have thought. Guess not.
Random association: watched the Fog of War doco the other day, about Robert McNamara. The Cuban Missile Crisis was discussed, and McNamara told an anecdote about sitting down with Castro and hearing that there were already nuclear missiles in Cuba, and that Castro had asked Khruschev to launch them at the US, knowing full well that Cuba would be destroyed as a result. McNamara’s eyes boggled as he told this story. He said Castro explained himself only by saying, “If it had been you in my position, you would have done exactly the same.”
Anyone reading this been to Cuba? Impressions?
