Obviously, more than incompetence was on display here. The intelligence agencies deliberately distorted the intelligence, and only someone with naivete the size of a blue whale would think that Bush was forced into war with Iraq, that he was open-minded and the intelligence convinced him to go to war. Anyone who is honest with themselves knows that the fix was in on September 11, 2001, or even before.
So, as Mr. Alam says, either the intelligence agencies were so paranoid that they deliberately distorted the intelligence, which benefitted Bush and his goals, or else the administration pressured them into distorting it.
Considering how much venom has been dished out against the CIA by the neocons for its failure to supprt Ahmad Chalabi or its to be sufficiently pro-war, or how much has been ladled out to the State Department for the same offenses, I seriously doubt that the intelligence community was paranoid, at least not towards Iraq.
So we all know who is to blame for the intelligence
That is all.
