Well, if i got duel citizenship with say Belize, and the US didn't require me to 'cancel' my US citizenship, then I could fly back to Belize and then to the US with my Belize passport under the guise of being a Belizean. So assuming that the US is cool with 'sharing the love' I could go to Cuba as a Belize resident? I bet US rules would still somehow apply, bummer.
