One is that [the WMDs] were spirited out of Iraq, which maybe is the worst of all possibilities, because now the very thing that we were trying to avoid, proliferation of weapons of mass destruction, could be in the hands of dozens of groups. Second, that we had bad intelligence. Or third, that the intelligence was satisfactory but that it was manipulated, so as just to present to the American people and to the world those things that made the case for the necessity of war against Iraq.
Of course, the other, probably true possibility -- that everything we've been told has merely been an excuse handed to the American public to hide the real rea$on$ for the war -- completely escapes the senator.
