@georgeob1,
Do you really believe we had nothing to gain from the the first Gulf War than the reluctant thanks of the Kuwatis?
Put aside whether or not there is anything to be gained, strategically, by coming to the rescue of the defenseless when they are beset by the naked aggression of a neighbor , it's pretty clear that Iraq's invasion of Kuwait was the opening move in an attempt by Saddam to assume control of the region's oil.
If unopposed in Kuwait, it would only have been a matter of time before Saddam found a pretense to invade Saudi Arabia with weapons purchased with the treasure stolen from Kuwait.
Surely you believe the US had a strategic interest in keeping the Saudi oil fields out of the control of Saddam, and if so, why wait until he actually attacked Saudi Arabia?
There is every reason to believe that once in possession of Kuwait he would, eventually, invade Saudi Arabia (although it may have followed the conquest of the smaller Gulf states), and that he would have, militarily, been in a better position to do so, than when he invaded Kuwait.
Rational people often make the mistake of predicting the actions of the irrational based on the parameters of their own view of reality.
The notion that Saddam would have been content with his conquest of Kuwait and not used it as a launching pad for even more aggressive ventures is not realistic.
The man had, in essence, absolute power in Iraq. If he wanted someone to die, they died. If he wanted the possessions of someone, they were his. If he wanted someone to do something, either they did it or they died.
Yet having god like power over millions was not enough for the maniac.
Whether an advocate of neo-conservatism or real politik, it's pretty damned clear that the US has a very deep strategic interest in the uninterrupted flow of Middle East oil.
To think that a successful Iraqi invasion of Kuwait would not have put that interest in peril is pretty myopic.
