"a missile shield over Washington, DC was deactivated several weeks before 9/11"
Lets see - first, such a system would be illegal under the ABM treaty. Second, there is no operational missile defense system (or have you missed the constant litany of failed and rigged tests) Third, it takes a long time to design and put such a complex system in place - therefore it had to have been done in the Clinton years. Fourth, you can provide absolutely no proof of such a system. Do you therefore believe that Bill Clinton secretly funded, designed, tested and installed an illegal missile defense system to protect Washington DC?
"Pentagon's Office of Naval Intelligence intentionally was set up to be killed off on 9-11"
ONI is not located in the Pentagon - they have a huge complex in Suiteland MD.
http://www.nmic.navy.mil/As to the war games in Alaska, you do realize that the AF permanently stations its most capable F15's in Alaska as it is the closest state to Russia? There was no need to move aircraft north. Even if they did move some, so what? How many aircraft do you need to defend the east coast - do you believe that they left every airbase on the east coast deserted?
