Columbia fed a monster.
He was invited to speak at a maajor American university. Bollinger cut him down at the start of the speech , but hundreds of students applauded his response. How do you think the twisted mind of Ahmadinejad intepreted this? He probably took it as a sign of support from a large segment of the population in the US. If so, then he probably now feels that he can push harder and make even more demands. IMO, what happened yesterday was a dangerous thing.
