While it is true that the president in Iran is more like the typical US vice president and is relatively powerless, he can nevertheless set a tone and initiate policies slightly different from those of Supreme Leader Ali Khamenei. Iran is not yet a totalitarian dictatorship, and Khamenei himself has sometimes been forced to tack with the wind. Any change will be slow and at the margins, but it could nevertheless be significant in a very polarized world.
