Ahmadinejad’s bland self-assurance is partly a matter of style, for no politician ever wants to display weakness before his adversaries. But in this third interview I’ve had with the Iranian president, I had the sense that he genuinely believes the world is going Iran’s way. He sees an America that is facing reversals across the Muslim world — in the wars in Iraq and Afghanistan and most recently, in dealing with the Arab uprisings. Close U.S. allies such as Egypt’s Hosni Mubarak are gone, and Ahmadinejad is still standing.
