When this is all said and done, I would like someone to explain to me why Saddam waited while we moved men and machinery into the area. Why didn't he attack when he had the numerical superiority?
Because he and most of rest of the world thought it was
all a bluff, and that the U.S. didn't have the balls to really take large scale military action.
Remember our will as a nation was supposed to have been destroyed by Vietnam.
I also recall (somewhat dimly) reading one of the books that came out soon after the Gulf War (by Norman Friedman, I think) that Saddam's troops weren't really capable of moving in force into Saudi. If my recollection is correct, many of his tanks broke down moving through the desert to the Kuwait-Saudi border. I'll try to verify that.
In any event, we shouldn't plan on being lucky twice. This time Saddam knows that if we go in, its because we are going to put his head on a pike. Under these circumstances he has no reason to hold anything--including WMD--back.
