Holier than thou, seems to be running its course.
The U.S.A does plenty of shitty things to plenty of other countries. Why is that? I don't see any other countries in the world trying to help as many people as we do. When you pay out Billions to help others sometimes you have to step on people to get things done. I do think it is arrogant to assume that the American way should be everyones way though. Some things work for some countries and others don't.
As far as enviromental concerns. We have the ability to set the example for the rest of the world to follow but we don't. I don't have an answer for that problem though. I do think Bush is stupid for spending taxpayers money for another (read:something that tells him what he wants to hear) study to decide if Global warming is real.
