Iranian President Mahmoud Ahmadinejad questioned the official version of the Sept. 11 attacks and defended the right to cast doubt on the Holocaust in a tense appearance Monday at Columbia University, whose president accused the hard-line leader of behaving like "a petty and cruel dictator."
Ahmadinejad smiled at first but appeared increasingly agitated, decrying the "insults" and "unfriendly treatment." Columbia President Lee Bollinger and audience members took him to task over Iran's human-rights record and foreign policy, as well as Ahmadinejad's statements denying the Holocaust and calling for the disappearance of Israel.
"Mr. President, you exhibit all the signs of a petty and cruel dictator," Bollinger said, to loud applause.
He said Ahmadinejad's denial of the Holocaust might fool the illiterate and ignorant.
"When you come to a place like this it makes you simply ridiculous," Bollinger said. "The truth is that the Holocaust is the most documented event in human history."
