Something to chew on. Saddam rolled into Kuwait because he felt (or so he said) it was part of Iraq. One of the fears was that he might not stop there and would go onto take Saudi Arabia.
If he had, would we be better off? Saddam enjoyed decent relations with the U.S. prior to his invasion of Kuwait. Would it be better to have a secular tyrant running the Saudi pennisula rather than the shaky royal family that is there now? The royal family is ripe for violent revolution with the extreme wahabbis they have tolerated and allowed to grow. If the extremist take over Saudi Arabia, wouldn't that do more to destabalize world oil markets rather than some dictator who we could work with?
Maybe 9/11 doesn't even happen because Bin Laden is obsessed with Saddam and likely our military bases wouldn't be on the penninsula.
Too late now but an interesting acadmenic discussion.
