“Israel's Next War?” explores problems posed by Zionist hard-liners who want all Arabs out of Israel. The fear is that their provocations could lead to wider conflict. The hour includes interviews with hard-liners and Israeli officials, and profiles of Shlomo Dvir and Yarden Morag, who were convicted of attempting to blow up an Arab school in Jerusalem. This “enemy within,” as producer Dan Setton calls the militants, “is in many ways a mirror image” of Islamic terrorists.
