There have been dozens of threads here on DU about the
Bush administration denying visas to Cuban musicians, doctors, inventors, researchers, even baseball squads, etc etc who want to come to the US to lecture or attend lectures, or to attend summits, or to receive awards - all denied by the US government.
Cuba does no such thing.
Cubans and their government want normalization between the US and Cuba, and they have thrown their doors open to us, but, it is our US government that prevents
what the majority of Americans want their government to do - normalize relations. Worse yet, the US government forbids and has criminalized travel to Cuba by Americans - something that Cuba hasn't done.
