I advise everybody to watch this interview with Iranian President Mahmoud Ahmadinejad, he answers the questions asked of him very informatively and with factual arguments. The interviewer (Mike Wallace) clearly shows his bias and lack of knowledge throughout the interview, as Ahmadinejad states "Are you a journalist? This is not journalism.".
This doesn't mean I agree with everything said or blindly believe President Ahmadinejad, but you certainly can't write him off as a madman intend on destroying the world.
