Ahmadinenutjob at the Columbia Zoo

The circus came to town...and visited the zoo. But you really couldn't tell the difference.

Columbia President Lee Bollinger opened the program with a blistering introduction in which he lambasted Ahmadinejad for calling for the annihilation of Israel, denying the Holocaust and supporting the execution of children, and told the leader of Iran that he resembled "a petty and cruel dictator."

Bollinger levied repeated criticisms against Ahmadinejad, calling on him to answer a series of challenges about his leadership, blasting his views about the "myth" of the Holocaust as being "absurd," and saying that he doubted he "will have the intellectual courage to answer these questions."

"You are either brazenly provocative or astonishingly uneducated," Bollinger told Ahmadinejad about the leader's Holocaust denial. "Will you cease this outrage?"

After sitting through Bollinger's rebuke, Ahmadinejad rose to applause, and after a religious invocation, opened his remarks by objecting to the scolding, saying it was insulting to be spoken about that way.

"At the outset, I want to complain a bit about the person who read this political statement made against me," Ahmadinejad said. "In Iran, we don't think it's necessary to come in before the speech has already begun with a series of complaints ... It was an insult to information and the knowledge of the audience here."

He said Bollinger's speech was full of "insults and claims that were incorrect, regretfully," and accused Bollinger of offering "unfriendly treatment" under the influence of the U.S. press and politicians.

He did not address Bollinger's accusations directly, instead launching into a long religious discussion laced with quotes from the Koran before turning to criticism of the Bush administration and past American governments, from warrantless wiretapping to the bombing of Hiroshima and Nagasaki.

Just absolutely ridiculous.

This man is the leader of a nation that sponsors terrorism. His nation aids the enemy in Iraq. His government contributes to the death of Americans every day.

Why wasn't he arrested once he left the United Nations?
