I don't see the rationale for the embargo. We trade with other communist countries and arab countries with human rights records as bad or worse than Cuba. The key is the other countries have products we need (ie, oil, cheaply manufactured products.) I think both sides are determined not to blink first. If we cave then the Cuban government has a huge propaganda victory. If there markets are opened to our products and services, maybe the government will feel threatened. Either way, the only ones suffering are the Cuban people.
