Here is Colin Powell defending himself and the original decision to invade Iraq by invoking the 2002 NIE.  That would be the rapidly thrown-together report that Sen. Bob Graham, as Obama reminded Edwards at the recent debate, cited when giving his reasons for voting against the resolution to authorise the President to use force.  If it was possible to conclude that war was not necessary or prudent after reading the 2002 NIE, why would anyone at this late stage continue to cite as some sort of authority, as if its findings made war the obvious choice?
