It's a false dichotomy to say the Jews and the Arabs, since there are Jews who are Arabs. Arabs are just people who speak Arabic. The "Arab world" simply refers to the part of the world in which the Arabic language predominates. The term Arab doesn't have anything whatever to do with anyone's religion or any other characteristic besides language. Although I know it is convenient to try to lump all Arabic speakers into one big generic group when one is trying to justify theft.
