In this episode of Head to Head, Mehdi Hasan challenges Robert S. Wistrich, one of the world's leading scholars of anti-Semitism, on why he thinks criticism of Israeli policies is a modern manifestation of historical anti-Jewish hatred.  Is anti-Zionism a new form of anti-Semitism? Are boycotts driven by prejudice or principle? And is a criticism of the Palestinians and the Muslim world Islamophobic?  In front of the Oxford Union audience, and with the help of an expert panel, we discuss the complex relationship between legitimate criticism of Israel and illegitimate racism.  Joining this discussion are:  • Hannah Weisfeld, the founder, and director of Yachad, a pro-Israel, pro-peace movement.   • Jonathan Arkush, the vice-president of the Board of Deputies of British Jews.   • Richard Kuper, the founder of Jews for Justice for Palestinians.   • Sharif Nashashibi, a Palestinian commentator and former advisor to the UN
