Spartan - I believe that the US not trading with Cuba is due to the large community of Cuban escapees and exiles in the US. They view trading with Cuba as playing with the bad guy. In some ways you can see a capitalist revolution in China but in other ways that money flow continues to support an oppressive regime. There are no promises that trade will improve the life of the ordinary citizen, especially ethinic or religious minority groups.
