Another Turning Point?

Here I am watching Mike Wallace on Fox News Sunday engage in what could only be called a softball interview with Richard Lugar, who just said he doesn't know if he supports sending new troops to Iraq or not. At any rate, Wallace opened up the interview with a series of questions designed to frame the execution of Saddam as yet another, you guessed it, "turning point" that "sends a message to Saddam's dead-enders" that he's not coming back and the insurgency is going no where. I'm not sure who first noted this, but if you keep having turning points, then pretty soon you're just going in circles.
