Art - I don't know if the the joke is antisemitic but it certainly laughs at the man dying of thirst. The fact that the joke depicts specific ethnic groups makes it distasteful. Would the joke have been as funny if all three characters were from the same ethnic group? So what is so funny about the power imbalance emphasized by choosing an insensitive Jew and a dying Arab? Taliban was obviously inserted to make the joke more palatable.

Ethnic jokes stink of stereotypes.
