Certainty.

Ron Suskind wrote a piece for the New York Times Magazine on President Bush's faith and how it guides him in his job. Much of the President's resolve comes from the fact that he prays on all matters, allows God to give him clarity, and then doesn't stray from the path. Or something.
Here's an embarassing anecdote from the piece (clearly Bush hadn't been praying about world history or God was messing with his memory):

In the Oval Office in December 2002, the president met with a few ranking senators and members of the House, both Republicans and Democrats. In those days, there were high hopes that the United States-sponsored ''road map'' for the Israelis and Palestinians would be a pathway to peace, and the discussion that wintry day was, in part, about countries providing peacekeeping forces in the region. The problem, everyone agreed, was that a number of European countries, like France and Germany, had armies that were not trusted by either the Israelis or Palestinians. One congressman -- the Hungarian-born Tom Lantos, a Democrat from California and the only Holocaust survivor in Congress -- mentioned that the Scandinavian countries were viewed more positively. Lantos went on to describe for the president how the Swedish Army might be an ideal candidate to anchor a small peacekeeping force on the West Bank and the Gaza Strip. Sweden has a well-trained force of about 25,000. The president looked at him appraisingly, several people in the room recall.

''I don't know why you're talking about Sweden,'' Bush said. ''They're the neutral one. They don't have an army.''

Lantos paused, a little shocked, and offered a gentlemanly reply: ''Mr. President, you may have thought that I said Switzerland. They're the ones that are historically neutral, without an army.'' Then Lantos mentioned, in a gracious aside, that the Swiss do have a tough national guard to protect the country in the event of invasion.

Bush held to his view. ''No, no, it's Sweden that has no army.''

The room went silent, until someone changed the subject.

A few weeks later, members of Congress and their spouses gathered with administration officials and other dignitaries for the White House Christmas party. The president saw Lantos and grabbed him by the shoulder. ''You were right,'' he said, with bonhomie. ''Sweden does have an army.''

Cringe.
