Here is a Washington Post story about international polls. This seems to be the gist of it.

Not surprisingly, the number of people holding a favorable view of the United States has plunged in the wake of the war. Last summer the percentage of Germans who viewed us positively was 61 percent; today it's 45 percent. In France, our favorability rating has declined from 63 percent then to 43 percent now. In Spain, where Prime Minister Jose Maria Aznar's government supported the war, U.S. favorability ratings are down to a scant 38 percent.

I may comment more later, especially if I find the original data.
