Well, the Mexican is supposed to be Hugo Chavez but I'll be damned if I can figure out the guy sitting next to him. Maybe he's representing the Zionist conspiracy that wants to destroy America.
More likely he's Iran's Supreme Leader Ali Khamenei. The guy who actually makes the decisions in Iran. Though right-wing nut jobs think Ahmadinejad is the one in charge and the new Hitler. And has parties with Latin American dictators apparently.
