The New York Times quotes him as saying The essence of the middle east conflict has always been and remains the persistent enmity of Arab states towards the Jewish national renaissance,  As UN envoy, he made headlines for "scolding" a group of 133 American Jewish law students protesting Israel's invasion of Lebanon and protesting Jewish settlements in West Bank and Gaza. He questioned the factual, as well as the moral position, of the students' view, saying that they "have not given the slightest indication of their willingness to bear any personal consequences of their patronizing and fortuitous advice.
