Ron Paul answered the silly scenario about Iran at the last Fox debate. Basically he says that we don't have to resort to war with Iran. And it is up to Congress to decide if Iran is an imminent threat to our national security and to go to war, not the President. There is no reason to nuke Iran or invade Iran. They do have the right to develop a nuclear energy program under the NPT.
