I've been skimming over different analysis of this for a while, but Juan Cole has finally stepped in and done a comprehensive piece on how petty politics and the need of the Bush administration for positive publicity during the Democratic National Convention may have led them to blow the cover of the only double agent we have ever had in Al Qaeda.

We already know Rove is willing to blow covert intelligence assets for petty political payback. Now he may have blood on his hands too.
