As I see it, if the USA hadn't gone ape over Nationalisations in Cuba*, Castro would either have been overthrown or retired by now - With the USA as a trading partner and free access both ways, can anyone here see the rigid regime standing? (especially if there was an extradition treaty).
By the bye, if, as has been stated earlier, "...alcoholism among men is probably the biggest social problem in Cuba..." which would you rather have as a problem, drunks or crack-heads?

* Given America's attitude to Nationalisation, I look forward to the return of (or compensation for) all the property seized from Loyalists, displaced, following America's own revolution.
