Neither one knows much about anything. Bryan reports on a piece from BBC World Today:

…about Mahmoud Ahmadinejad, the President of Iran, essentially saying that the office of President actually is not that powerful, and there is no reason to believe that Ahmadinejad actually knows what he is talking about when it comes to the nuclear program. Mr. Ahmadinejad has no scientific training and was the mayor of Tehran until his election.

In other words, don’t pay any more attention to ahmadinejad than you would to the former Texas governor who also has no scientific training.
