The Anti-Defamation League on Thursday came out against calls by some Jewish groups to boycott the University of California at Irvine  (in enrollment and donations) because of controversies over campus events related to Israel, most recently a talk by the Israeli ambassador to the United States, who was repeatedly interrupted  by protesters. The ADL praised the university's leaders for responding quickly in condemning the interruptions, even while noting concerns over numerous anti-Israel events. However, the ADL said that a boycott of a university would not be an appropriate way to respond even to legitimate concerns. Abraham H. Foxman, ADL's national director, said: "We are surprised that those who call for a boycott fail to recognize that it is a double-edged sword that legitimizes a tactic so often used against Jews and Israel, particularly in academic settings. We believe academic boycotts are inappropriate, harmful and counterproductive, and will not work to resolve the situation on campus."
