Here is Jonah Goldberg with a good essay on Bush’s speech and his way. The concluding paragraph:

"President Bush laid things out clearly when he said, "We will not deny, we will
not ignore, we will not pass along our problems to other Congresses, to other
presidents, and other generations. We will confront them with focus and clarity
and courage." And it struck me; the first metaphor for Bush was still the best.
He is a cowboy, in the best sense of the label. He’s got a moral compass that
points true north even if he’s got to zigzag to get there. He speaks plainly. He’s
not dumb, but he also doesn’t need to be the smartest man in the room because
he’s got right — ’providence’ in his words — on his side, and he knows the
difference between shinola and other substances. This may not explain the
dynamics of why Saddam’s got to go right now. But after he’s gone, when the
Iraqi prisons and archives of terror are opened and the Iraqi people are free,
Bush can simply say of Saddam, in cowboy parlance, "He needed killin’"; and
everyone will understand."
