Difficulties in the Middle East crisis are exacerbated by incitement by both Jewish and Muslim fundamentalists who use their religious authority to incite their congregations against members of the other religion. For example, rabbis proclaim that many Arabs are not worth a single Jewish fingernail. Muslims claim that the mere acknowledgement of Jews is nothing but treachery to the way of Islam. In the UK, for example, Muslims hold anti-semitic meetings on university campuses.
