Voice of the Prophet

I don't agree with everything this man has to say, but he's certainly worth listening to. Here's a blurb about the video:

A truly chilling example of foreshadowing, The Voice of the Prophet is an interview with Rick Rescorla, the head of security for the investment firm Morgan Stanley Dean Witter. A retired Army colonel, veteran of combat in three wars and a survivor of the 1993 bombing of the twin towers (in which he saved the lives of hundreds of Morgan Stanley employees), Rescorla was killed in the WTC attacks of September 11, 2001. In this interview, Rescorla all but predicts the events that lead up to the September 11 attack and the war on terrorism that followed.

You must watch the entire video before answering this question: what thoughts do you think were running through his mind on September 11th? Do you think if he'd had the opportunity, he'd have reconsidered some of what he said here?
