I think whenever Ahmadinejad opens his mouth in forums, especially in front of the U.N. General Assembly, those that are listening, especially Western officials, European, American, even Chinese and Russian officials, I think, after listening to Ahmadinejad, they have even less confidence that there exists a mature political leadership in Iran which is amenable to some type of a diplomatic compromise.

I really believe that actually Ahmadinejad undermines Iran far more than he enhances Iran's status. And I think we have to go back to what FDR said, you know, speak softly and carry a big stick. I think Iran under Ahmadinejad, they speak loudly and carry a small stick.

President Ahmadinejad is not the most powerful individual. At the same time, he is reflecting Iranian views right now, so it's difficult to neglect him.And in the context of domestic U.S. politics, it's very difficult to ignore him.

The most important individual in the Iran is not President Ahmadinejad. It's the supreme leader, Ayatollah Khamenei. He was elected, but we're not talking about free and fair elections in Iran. There are certain vetting processes which take place.

The Iranian government prevented journalists from marching in solidarity with the victims of the Charlie Hebdo massacre yet it organized flag-burning protests against the French embassy, that hasn't ingratiated them to a French nuclear negotiating team that is deeply cynical about the nature of the Iranian regime.
