As I've been saying all along, history is not going to treat Bush kindly. He is a failure at everything he's undertaken since becoming president. Unless, of course, you consider weakening environmental regulations, tanking the economy, tax cuts to the wealthy, waging an unnecessary and costly war that we cannot extricate ourselves from, implementing the Unpatriot Act, disregarding international law and treaties, etc. to be successes. In other words, with successes like these, we don't need failures.
If you're saying that now that he has a second term to make things right, which would make him a great president, that's nuts. Kind of reminds me of the firefighter who sets fires, only to be the first on the scene to put them out, so he can be viewed as the hero. I don't think so.
Again, the historians will write about these things, and it's not going to be pretty.
