You are, of course, correct. I'm afraid though that this line of thinking will lead to even more tin foil hat theories regarding who instigated 9/11, but I know you did not mean it in that way (and to be clear, I'm not being sarcastic).
"Bluntly put, without 9-11 Bush would have been a one termer."
Without 9-11, no one would be considering Rudy for anything.
