Whether there are sanctions or not, the Cuban leadership will keep on eating. Plus I can think of several countries far worse than Cuba, which we have very good relations with.
The Cold War has been over for years. Cuba is not a threat to us. It's time we started trading and talking with them.
We shouldn't further relations with a country as crappy as Cuba. Plus, it's not like Cuba can do anything to us.
The place is a nightmare. Blockade it and forget about it.
