"Why are they picking on Chile and Argentina?"
They are picking on us because the Menem-era ended down here. Carlos Menem, president 89-99 had a close relationship with my friend Clinton
(Argentina has been in the Visa Weiver program from 94-2002.) Now with Bush, things have changed... It seems they don't like us anymore.
Anyway I still have my US toursit visa, but may don't...
