Iran may have the WMDs that left iraq, most of them probably aren't a long range threat, but would be devistating on ground troops. We have the ability to do this without committing ground forces. The goal is not liberating iran, its elliminating a nuclear threat, with a colateral regime change. IMO, this will be air only, and a very short event, probably with only a few planes actually doing the deed, and others for support, also with destroyer based missles, quick, hard, and effective. From what I have seen on T.V, the iranian people aren't pro weastern, but aren't as radical either. Several clerics think the iranian president is crazy, and blasphemous, and wouldn't mind seeing him gone. As usual, this will end up being a U.S. action, with only token support from other nations.
