In a speech in New York at the Lubavitch Rebbe's 43rd International Meeting of Messengers (the Meeting of Messengers, the main annual event of the Chabad-Lubavitch movement), Rabbi Jacob Shapiro, a US citizen and practicing Jew, challenged Benjamin Netanyahu's claim that he represents the Jewish people around the world.
He explains that being Jewish does not mean being represented by the Israeli government or regarding Israel as one's nation state.
