Great Digby post, linking to The Medium Lobster, as well. O, what a beautiful morning....!
Truly, I am not sure that even the architects of this mess really know why they did it - the rationales seem to shift under their feet every time they are pressed to explain. There are clues in the PNAC agenda I posted below (Shorter: "We must have the world's Biggest Balls!"), but the enterprise has been spectacularly counterproductive. It's interesting to me that "moral clarity" was a PNAC rhetorical trope (see the very last paragraph) all the way back in 1997, quite a long time before the 9/11 attack made that phrase a tin drum. History - that thing that Dear Leader thinks we will all be dead before it speaks - is going to pee on them.
