Ronald Reagan would not have said, "You are either with us, or with the terrorists!" (which is a HUGE ultimatum), and then, several months later, be kissing the fat A$$ of the Saudi Princes, whom he had over to his house, and who funded and continue to fund al Quaeda, and who organized 9/11.
That's just ONE thing.
Ponder that.
The Saudi ruling family has kept the region balanced and US-friendly since they took control. Without them history in the region and the world would have been very different.
They have supported and financed every mission asked of them and have condemned bin Laden from the beginning of his hate campaign in the early 90's.
The radicals of 9/11 became radicalized in German and London mosques...not Saudi.
