I don't know enough about this guy to make sense of what or why he's calling for this. I think Iran has a lot of internal pressure regarding dissatisfaction with Mullah rule but surely he must realize that the Iranians will rally around the Mullah's if the US invade and a whole lot of Iranians will die along with Iran's infrastructure destroyed. Does he believe that if the US invades the Iranian populace will turn against the Mullahs?
If Iraq is an indication of what happens after the U.S. invades, why would the Iranians want some of that action?
