Sure have hearings ,knock yourself out.. Call in all the intelligence people from all over the world to testify what they knew prior to the war . Call in the intel experts from a decade worth of work from 2 administrations that swore to the fact . Call in the UN inspectors who were saying weeks before the war that the WMD was still there . Maybe they will ALL say they were fooled by the all clever Saddam Hussein ,or even better... fooled by Chalabi .
