I've found the whole Chalabi story a bit convoluted and hard to follow, but this really lays out the whole thing in short bites, complete with links to back up each one. Must read.
For what it's worth, though, I disagree with the author's "answer" to the quiz. I think that the most embarassing thing is the whole: that all of the Bush administration foreign policy for the last three years has been dictated by the Iranian Intelligence Agency. Ugh.
