I don't give them a pass. They had professional war planners who told them otherwise. Those professional war planners were either fired, Shinseki, or beaten into submission to drink the kool aid, Franks. It is no surprise that the only professional war planner high in the administration, Powell, was the most reluctant person to sign onto the program.
Maybe a surprise to the Days of Our Lives/American Idol crowd but those in the Administration should have had time to resarch the issue and know better.
I thought the weapons inspectors debunked so much of the intelligence that the major conclusions were highly suspect.
