Just because Bush asked for help doesn't mean the U.S. absolutely needs it. With all this political correctness now, these little European crap countries think they are on par with the U.S. Lets get real for a moment. The U.S. could easily destroy the entire world, seriously. President Bush simply asked for a little bit of help policing Iraq.
Iraq was our friend in the early 80s. If all these U.N. countries keep voting against us, maybe one day they will see M1s rolling down the streets of their capital city.
So far, the U.S. has lost less troops in the war/aftermath than a single day of traffic deaths on U.S. highways.
