So is Cuba really that much of a threat for us anymore? Yes, I understand the roots going back to when Fidel was in power, and the Russians (now defunct) were his main allies, but is there really anything to fear from a country that has a fleet of vehicles that were essentially new when "Leave it to Beaver" was a first run sit com?

I know, they're communist, and such, but we do business with a lot of communist countries. In today's environment, what interest does it serve to exclude Cuba as a trading partner? We do business with China. Why would we not choose to do business with Cuba, other than the fact that they have been our enemies since Kennedy was in office?

Just wondering. Must be one hell of a grudge.
