It seems like most of the arguments being put forward have a hard time thinking about the reasons why the United States invaded Iraq. People seem to think it was just a "mistake" and tend to chalk it up to George Bush incompetence, and/or making the defense industry rich, etc.
Haven't any of you played Civilization?
If you're running a country, and then there's this other little pest of a country that has a track record of attacking people, is technologically inferior, AND is sitting on a nice resource such as oil, wouldn't you want to invade it and make your country stronger (even if you knew there was a chance of some of your military units dying in the process)?
People play games such as Civilization and don't realize that this stuff happens in the real world too.
