I think many countries feel the United States war in Iraq is not justified. No weapons of mass destruction were ever found and nothing was ever proven that Iraq had any involvement in the September 11th attacks. Even here many people believe that the war sparks of vigilantism.

Historically the United States has not gotten immediately involved in wars just on the say so of countries we had pacts with. WWII our involvement came only after the Japanese bombed Pearl Harbor. In WWI other European countries were fighting for several years before we became involved (I don't remember the trigger that caused our involvement).

My point is that the United States did not generally rush into wars with countries we had pacts with. An exception was the Vietnam War - which (if I am not mistaken) wasn't really considered a war until history made it one. At the time it was still considered a police action.

I think that other countries would have more willing to help if Bush had declared war on Osama Bin Laden and his followers, or if he had more proof that Saddam was directly involved in the attacks. September 11th outraged the entire world, but Bush's attack on Iraq is too far of a stretch for most countries to justify to their people. JMHO
