Your logic is not sound. Look at the bigger picture, not just the little weird things you see in the school. Why have the terrorists be Saudis if the goal was to use some excuse to invade Afghanistan and/or Iraq? Surely they could pick the people if they could pull the rest off, and making them be unambiguously from one of the country's slated for invasion would cut out a lot of the headaches the administration got. Once again, why be at the school at all when he could have been in the Oval Office ready to give a speech and not have those minutes of embarrassing dithering to be played in a Michael Moore documentary? Why have four planes be hijacked when only one flown into the Empire State Building would have been a lot less risky and just as traumatic? Just imagine if the Pennsylvania plane had managed to make an emergency landing rather than a crash. That's a lot of people to keep quiet. Why even do this at all, when there has never been a reason to be in Afghanistan besides revenge and there would be much easier ways to invade Iraq (goading Saddam back to Kuwait, exaggerating some attack on the Kurds, etc)?
I could go on. As I said before, Darwyn, you are in the conspiracy theorist zone. Any little, little thing which could possibly be interpreted in a revisionist way is presented as incontrovertible proof of a plot, while anything which contradicts the theory (no matter how compelling, no matter how much evidence there is) is ignored. You're an idiot, and a pathetic one at that.
