If you value your sanity, never, ever, ever listen to GOP blowhards like Tom Coburn and Lindsey Graham discourse at length on Iraq. The arguments are so transparently ad hoc, disingenuous and overdetermined they’ll make your head explode. (Sample line from Lindsey Graham: “This is the most successful counter-insurgency operation in the history of the world!”)

Kevin Drum sums up the pro-surge argument smartly with this line: “I guess the surge is working so well that we have to keep it up forever.”
