That's the summation President Bush delivered as he wrapped up his press conference Tuesday night. It's the message he emphasized throughout: Our commitment. Our pledge. Our word. My conviction. Given the stakes in Iraq and the war against terrorism, it would be petty to poke fun at Bush for calling credibility "incredibly important." His routine misuse of the word "incredible," while illiterate, is harmless. His misunderstanding of the word "credible," however, isn't harmless. It's catastrophic.

...

Outside Bush's head, his statements keep crashing into reality. Tuesday night, ABC's Terry Moran reminded him, "Mr. President, before the war, you and members of your administration made several claims about Iraq: that U.S. troops would be greeted as liberators with sweets and flowers; that Iraqi oil revenue would pay for most of the reconstruction; and that Iraq not only had weapons of mass destruction but, as Secretary of Defense Rumsfeld said, 'We know where they are.' How do you explain to Americans how you got that so wrong?"

Inside Bush's head, however, all is peaceful. "The oil revenues, they're bigger than we thought they would be," Bush boasted to Moran, evidently unaware that this heightened the mystery of why the revenues weren't covering the reconstruction. As to the WMD, Bush said the chief U.S. weapons inspector in Iraq had confirmed that Iraq was "hiding things. A country that hides something is a country that is afraid of getting caught." See the logic? A country that hides something must be afraid of getting caught, and a country afraid of getting caught must be hiding something. Each statement validates the other, sparing Bush the need to find the WMD.
