The Guardian is now running on its front page a full-on mea culpa from Rafid Ahmed Alwan al-Janabi, better known as "Curveball", and the seed information source used to justify the 2003 Iraq war.
By now, eight years on from Colin Powell's UN speech, it's not really news that the "evidence" used to justify the invasion was shoddy at best. But there is still a measure of shock seeing the actual guy behind the Curveball mask, admitting he made it all up for his own purposes (and to feed to the Bush administration's stove-piped intelligence operatives).
I'm guessing that for many of us here, the 2003 Iraq war was always considered to be a GWB presidency fait accompli, a war of choice and a massive diversion from finding and bringing to justice the 9/11 terrorist organizers. But the facts were selected to fit the policy and the cost be damned. It has been a very high cost.
