I'm sorry I don't even buy it not one bit. How can Bush not have known? I can't believe any elected government in this country was not informed on any future attacks on America. I truly believe that Bush ignored all the evidences that was gathered by the CIA.
He had the chance to prevent or to try to get Osama Bin Laden before 9/11, which he did not, He also had not try to get Osama Bin Laden after 9/11 either. What does that tell you?
That is because they chose not to act on the warnings that they had received for several years. Several years they knew and done nothing until the last warning was made July 2001, when Osama was about to launch a terrorist strike between July to Oct. of 2001 and that had been ignored also! So don't sit there and tell me Bush knew nothing.
