Or, to put it more long-windedly:
… the ultimate responsibility for this fiasco lies with Mr. Bush. Too often he has appointed, or tolerated, officials who oppose his agenda, and failed to discipline them even when they have worked against his policies. Instead of being candid this week about the problems with the NIE, Mr. Bush and his National Security Adviser, Stephen Hadley, tried to spin it as a victory for their policy. They simply weren’t believable.
Got it? Someone who (not for the first time) says things in public that simply aren’t believable ought to make sure that no one in the government contradicts him. Astounding!
