On March 3, 2015, Israeli Prime Minister Benjamin Netanyahu delivered an address to the U.S. Congress. In “the most anticipated speech to Congress by a foreign leader in many years” (Baker), as the New York Times would have it, Netanyahu emphasized the risks of a nuclear deal with Iran, which was being negotiated at the time. On the same day the Jewish American comedian Jon Stewart commented on Netanyahu's speech in an episode of The Daily Show, of which he was the anchor. This thesis interprets both performances as contradictory contributions to a discourse on Jewish American identity. It allocates this discourse along various dimensions of Jewishness, and analyzes the functions of myth and humor within these cultural negotiations. Furthermore, this thesis illustrates how Netanyahu paints the picture of a united and endangered Jewish people, in order to claim the authority of a spokesperson. Stewart, on the other hand, systematically undermines this authority and ironically uses stereotypes to refute the narrative of a homogeneous Jewish identity.
