JordanT: The Economist wrote an excellent article on Iran and the widespread disenchantment of the populace. They also pointed out that the hardliner government utilizes everything from voter intimidation to censorship (of opposition papers, media and other organs) to outright threats to keep the populace in line.
Iran is made up of well educated, literate and largely pro-American people. Iran is governed by militantly Islamic hardliners, who are fanatically opposed to the West, Israel and America. I would like to discount the utterances of President I-Am-A-Dinnerjacket, but history has shown the folly of ignoring those people that are either in a position to carry out their threats, or rapidly moving towards it.
