Schroeder wasn't anti-American, he was just anti-war. Schroeder didn't damage relations with the US, THE US damaged relations with Germany. The inciting event was the Iraq War, not the election of Schroeder. Its just basic logic man.

And there's something called common etiquette; especially at a summit. If you met with someone distinguished and someone that you essentially don't know, you don't just get up and give them a message. The biggest thing I have a problem about this here isn't the fact that he did this, but it just display's Bush's contempt of other countries and other world leaders. This is the same condescending attitude that he uses toward the press and American people. As if what they think don't matter, and he's right all the time. If he's viewed as the village idiot and someone that just doesn't take diplomacy seriously, then world leaders wont take him seriously and shit like what happens in North Korea and Iran happens.
