I think we (USA) need to keep our distance. I think the citizenry of Iran believe in an Iran free of this Ayatollah's rule, but any direct US intervention could severely backfire on all considered. They don't want occupation, and we have no desire ( or should have no ) desire to occupy and ruin another middle eastern country. It's going to take time, patience, and courage of the Iranian people to free themselves. Any direct action by the US will only end up making things worse for all involved.
