I can`t imagine or even guess at the number of people and the bureaucratic jumble it would require for even half of what the primitives beliefs to have been pulled off by the US government.
How many memos and authorizations would it take to get a person into the building to plant the explosive charges they all believe in alone?
All this and no leaks over the course of months of preparation? 
You just can`t be that irrational and deluded unless insane.
Tell me about it. I know people who where at the Pentagon when it was hit. They where NOT the type of people who would keep that secret. You gotta be real damn naive to believe that thousands of military personnel would keep a secret like that for 7 years, when you can't keep people shut up about failing spy satellites.
especially when every article written about the military nowadays has the following phrase somewhere in it: "on conditions of anonymity because they were not authorized to release the information."
as many people as that "conspiracy" would have involved, it would have leaked long before anything was accomplished. military leaders are still setting forth the secrecy around operation overlord as a master stroke, and that only worked because up til about 5 days before the execution of it, the only ones who knew what was going on were the planners.
and another thing, are we to believe that "the incompetent" GWB got that plan completed and executed in less than 9 months? the same guy they accuse of being too stupid to breathe?
Some say the plane into the Pentagon was actually a missile (not sure how they reconcile that with the fact of a lost plane) others say flight 93 was shot down,and then complain that the order to shoot down wasn`t given in time or complain that it was horrible when President Bush did authorize it.
All the stuff about the towers being a controlled demolition which a few simple google searches...
http://www.howstuffworks.com/building-implosion.htmreveals what a complicated and impossible to hide project that would be.
Yet somehow they can still believe that it was a conspiracy.
These fools live in a TV world of McGivers and The A-Team with a Jack Bauer and cigarette smoking man around every corner.......
and they think they should be in control of policy and government,that is what is really scary because some politicians will try to appease them at our expense and peril.
