If only the US could lose a war without huge repurcussions for the rest of the world. It might bring them down to Earth.
I'm not really bashing the US, but I'm getting the feeling that the current man (I still have my doubts about the 'man' part) in office doesn't realize that the US is far, far, FAR from invincible. The war in Iraq alone is overstretching them. As UT already said, another war will be suicidal (and not only to the US I might add).
Yes, America is the most powerfull nation on Earth. Period. But an even bigger superiority complex is the last thing we need right now.
