The castro brothers have been a remarkable political double act. They've had an influence on the world stage that's out of proportion to their country. Things in cuba looked much better when the money was flowing from soviet union. And i suppose since the collapse of the soviet union, where it's had to become much more self reliant. It's having a lot more difficulty in keeping its sort of once vaunted health and education systems working so well. I think it's a problem for them, internally as well as externally.
