What ever happened to the "Pottery Barn" rule?

From Think Progress, here's the National Review's John Derbyshire on why he's proud to count himself among the "To Hell With Them" hawks: "We dont particularly care whether the Sunnis, Shias and Kurds of Iraq put down their arms. We only want them to put down their arms against us ... One doesn't want to be accused of inhuman callousness; but I am willing to confess, and believe I speak for a lot of THWTHs (and a lot of other Americans, too), that the spectacle of Middle Eastern Muslims slaughtering each other is one that I find I can contemplate with calm composure."
