Is there any evidence that Cuba wants Guantánamo Bay returned? Setting aside that naval stations are still a valuable asset, this seems like the kind of decision that could have inadvertent side effects.
We could simply demolish the prison or lease it out or something if that is the offending factor here, although I vaguely recall that it is no longer used as such by the Atlasian government.
Cuba refusing to take our payments tells me they don't recognize our hold on it.
However I agree that such a thing could have unintended side effects. I lean against this bill for now.
