Could it possibly be this guy is lying to take away legitimacy from a claim that would support the effort in Iraq? Why should would he lie then? He had no motive. He has all the motive in the world now to discredit the liberation of Iraq to help his fellow Al qaeda brothers fighting there now. But the media who didn't find this guy's claims credible enough to report when he was making charges of Iraq's collaboration with Al Qaeda will suddenly find this guy a fountain of truth now that he supports their anti-liberation of Iraq biases.
Well, that's because they knew there was no connection between Iraq and al Quaida, so they didn't need to report anything this guy had to say. Journalists are so much smarter than people who actually work for a living. If working people were as smart as journalists, they would be able to figure out how to make money without working.
