"Two major American Jewish organizations helped block a prominent New York University historian from speaking at the Polish consulate here last week, saying the academic was too critical of Israel and American Jewry. The historian, Tony Judt, is Jewish and directs New York University's Remarque Institute, which promotes the study of Europe. Judt was scheduled to talk Oct. 4 to a nonprofit organization that rents space from the consulate. Judt's subject was the Israel lobby in the United States, and he planned to argue that this lobby has often stifled honest debate. An hour before Judt was to arrive, the Polish Consul General Krzysztof Kasprzyk canceled the talk. He said the Anti-Defamation League and the American Jewish Committee had called and he quickly concluded Judt was too controversial."
