No one, not even your greatest critics can refute your generosity. Which is why when attrocities like 9/11 happen, even the world capitol of the "axis of evil" (Tehran) holds mass vigils to mourn American victims. The problem with you yanks is that you always manage to erode any and all sympathy you accumulate with your own actions. Launching hopeless "crusades" all over the world and spiels like "with us or against us/silence=complicity" are responsible for your image. Change that, and you will see how fast your image improves. Also remember that traditionally, the Muslims (for example) always saw the US in a better light when compared to Europeans and even the Soviets (who supplied Egypt and Syria with weapons, but at the end of the day, were communists.) Think about this: even today, the most lunatic fringe groups like Al-Qaida see the US as a secondary threat. For them, the US is just a puppet of Israel (lol) who is making the US do all the evil things. So even they don't have a completely negative image of the US.
