Yes, we're all Bushbots.
First how do you know Bush didn't do anything? How do you know what was going through his mind? You think you can make snap judgments in a matter of minutes to shoot down civilian airliners? Boy that would give Michael Moore plenty of fodder for his next fict-u-mentary, wouldn't it?
What would you have the man to do? He's president of the United States, and his nation is under attack. Would you have him go to Washington, so he could be a target? I'm sure the Secret Service would have some objections to that. As bad as 9.11 was, losing our leader would have compounded the tragedy, making it like Pearl Harbor and the Kennedy assination combined. It would have a devestating effect on the American people. Of course, I'm sure idiots like Michael Moore wouldn't mind.
A. Michael Moore is a fat idiot. No argument there.
B. I've answered your "What should Bush have done?" question in several posts in this thread. If I was Bush that day, my first order, given the knowledge that now 2 passenger jets had been used to bomb the WTC, would have been to scramble jets to protect the nation's capital's airspace from further attack. Based on the well-known timeline found at thousands of websites (do a Google on 9-11 + Timeline), it's apparent that Bush had over 30 minutes to make this decision that might've saved the Pentagon. He did not do this.
I don't blame Bush for the attacks themselves nor think he could've prevented them from occurring based on what we know. I don't blame him for the Pentagon, since there's no guarantee that anything he did could've stopped that either. However, by doing nothing, he insured the Pentagon attack's success.
