CalPundit has a great summary for the main defense against the Yellowcake scandal:

Once again, we have the White House acting like a five-year-old. No, scratch that. More like a too-clever-for-his-own-good 15-year-old. "All we did is say that the British said it, and they did, so technically it's completely true."

Well put. Unfortunately, it ain't just the White House.
