The Myth of Moderate Mullahs: It's Still Khomeini's Iran - Reuel Marc Gerecht
It is astonishing that some Western analysts of Iran, and some senior U.S. government officials, actually believe that Khamenei and his kind would be willing to restore relations with the United States. Such a restoration would be an end to the revolution as we have known it.
For the mullahs this would be an unbearable defeat. Khamenei, Ahmadinejad, and Rafsanjani have no intention of letting this happen.
