Denial. Distraction. Disinformation.

Politically, America has been reduced to the condition where if a president really just believes something hard enough, it's sound evidence and a good basis for decision making. Via Ezra Klein, Murray Waas complicates even that:

The White House was largely successful in defusing the Niger controversy because there was no evidence that Bush was aware that his claims about the uranium were based on faulty intelligence. Then-CIA Director George Tenet swiftly and publicly took the blame for the entire episode, saying that he and the CIA were at fault for not warning Bush and his aides that the information might be untrue.

But Hadley and other administration officials realized that it would be much more difficult to shield Bush from criticism for his statements regarding the aluminum tubes, for several reasons.

For one, Hadley's review concluded that Bush had been directly and repeatedly apprised of the deep rift within the intelligence community over whether Iraq wanted the high-strength aluminum tubes for a nuclear weapons program or for conventional weapons.

For another, the president and others in the administration had cited the aluminum tubes as the most compelling evidence that Saddam was determined to build a nuclear weapon -- even more than the allegations that he was attempting to purchase uranium.

And finally, full disclosure of the internal dissent over the importance of the tubes would have almost certainly raised broader questions about the administration's conduct in the months leading up to war.

"Presidential knowledge was the ball game," says a former senior government official outside the White House who was personally familiar with the damage-control effort. "The mission was to insulate the president. It was about making it appear that he wasn't in the know. You could do that on Niger. You couldn't do that with the tubes."

Multiples warnings. Multiple occasions. And here's how success is measured these days:

In the end, the White House's damage control was largely successful, because the public did not learn until after the 2004 elections the full extent of the president's knowledge that the assessment linking the aluminum tubes to a nuclear weapons program might not be true. The most crucial information was kept under wraps until long after Bush's re-election.

But I'm sure history will vindicate this president's greatness . . . .
