More like 50 years of torture. Click the link in my signature. You can't blame everything wrong with Cuba on the Embargo, especially if they make Medical Equipment for international sales that is BETTER than the equipment they have for their people.
I've never understood the logic behind the embargo, if the Middle East, and to a lesser extent China, have taught us anything, its that people in countries under oppressive regimes (I know that Cuba has better healthcare than us, that doesn't change the fact that they don't have freedom of the press, excecute political dissents, and employ forced labor camps.) tend to throw their dictators out of power after they've had access to the internet and our communication devices for a bit.
Before the embargo, Cuba has onde of the better systems of medical care and education.
