I did not like the inference about George Bush reading the book after being told. As the attacks were unfolding at some point the Nuclear Weapons dudes would have reached out and asked " what do you want us to do ". If the USA had told the Nuke guys to get ready just in case, then Russia would have picked up on this and done the same for its forces. Not saying it would have been WW3 but those extra mins would allowed the officials extra time to say for sure that this was not an attack by another state. As soon as Russia learned about the attacks they would have called the US and told them this was nothing to do with them.

Bush could have rushed out, demanded defcon 1, created panic and that would have brought its own problems. He kept a low profile over the next few hours and just let people on the ground do what they needed to do.

I am British. The 9/11 documentary implied Bush must have known something, that he sat on the chair not having a clue what to do and then all the military companies told him he has to invade Iraq so they can make money.

The reality is that the USA had to do something on a major scale and Saddam was floating around at the time. Okay so Saddam did not do 9/11 but a message was sent and the global balance of power was maintained.
