Intelligence failure does not happen over night or within 3 years. It takes several years of neglect. The President and the Senate are responsible for taking care of the intelligence community. 911 commission said the CIA didn't have enough manpower or arabic linguist to take care of business. You reap what you sow.
Think of the enormity of the power the CIA has. They give a President intelligence, they make it sound as bad as possible, the President is left with nothing else to do but act. Especially after a direct attack on the United States. that kind of power is dangerous in the wrong hands. I believe the Cia has been infiltrated by politic hacks. Look at Plame and her stupid husband Wilson. is this the best the CIA will do, send their spouses out to get info.
