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.
Fidel Castro converted a nation with a higher per capita income than half of Europe, the lowest inflation rate in the Western hemisphere, a larger middle class than Switzerland, a huge influx of immigrants and whose workers enjoyed the 8th highest industrial wages in the world into one that repels Haitians. And this after being lavished with Soviet subsidies that totaled almost ten Marshall Plans (into a nation of 7 million) - an economic feat that defies the laws of physics.
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.
