Fantasies of Cuban exiles getting their property back should have ended decades ago, so our stupid treatment of Cuba was basically "we'll be mean...just because." We didn't bring down Castro and we contributed to the economic woes of the population, certainly after the fall of the Soviet Union. Still we'll get politicians bleating about our arbitrary human rights concerns because really we just cared deeply about the poor people of Cuba and their treatment by the government because that's always what motivates our policies.
