Some German industrialists, including auto executives, fear that the German government's opposition to war with Iraq will cause U.S. consumers to boycott German products. Those industrialists even mounted a public relations campaign against U.S. backlash that included an ad in the Sunday New York Times.
They should rest easy; their fears are baseless. Americans are not yet gung-ho about war with Iraq, and U.S. consumers don't seem inclined to give up their BMWs and Mercedes-Benzes in protest over anything.
It's one of the nice things about capitalism: Governments can disagree about foreign policy, but commerce unites peoples.
