Some blurb from ejits at the State Dept is not helpful.. But, the excuse for the protracted war in Iraq was to blame AQ.
Remember.. they said the war would be over in weeks, we would be welcomed as liberators and would pay for the war with Iraqi oil.
Guess nobody bothered to look at the British experience in Iraq and no one consulted with oil men. So... it was easy to shift the blame to AQ.
