(just to keep the trend going)
Anyway, it looks like we have some more fun stuff here:
1) to distract is citizens from the failing US economy
2) to get some oil in the proces
3) to make it look like he's actually doing something
4) because is nice advisors told him to do so.
1) The economy is failing because people are paying attention to it, since it is primarily psychological; if they stop doing that, markets will rise again. But people are actually paying more attention to the economy than ever before because of the prospects of uncertainty that go along with any war.
2) Which is a good thing eh? oil is better than no oil, simple common sense. (although the oil idea is just a silly excuse invented by the common rabbles for lack of anything better; it simply does not stand up to economic scrutiny)
3) Everyone is doing something all the time; you cannot do absolutely nothing, so he doesn't really need to show anything there. Besides, he is obviously serving the interests of the nation by conquering others.
4) See, he listens to others! he is a man of the people!

I would just love to see the UN make an example of the US if Bush would pull this off.
Actually what would happen in that case is that it would go the other way; the UN would be the one to lose credibility (which is already happening anyway), since the plan they were opposing turned out to work fine.

The thing about the UN is that they can only talk; they don't have the power to actually take any actions.
...an example to other states of the destructive power of the US...
This is one of the big objectives actually.

This reputation means a lot in the international world, since it increases the credibility of threats the nation makes in the future.
