Iran is not North Korea. It is not controlled by one family that demand a cult like devotion. Whenever given a choice between an extremist and a moderate, the Iranian people have chosen the moderate. Ahmadinejad was an aberration who was elected because of his success as Mayor of Tehran. He had to steal his reelection. The first popularly President elected after the Islamic Revolution wasn’t a religious fanatic but a French trained economist, Abollhasan Banisadr.Iran currently has very large population between the age of 20-30. Many of them are well educated but the current Iranian economy cannot support them. Iran desperately wants to become part of the international community but they cannot engage in a complete surrender to Western demands. They have to save face.The Iranians have had a nuclear program since 1950s. German intelligence was predicting that Iran was 18 months a from having nuclear weapons capability in 1986. Iran and it’s current leaders are not going to engage in behavior that will lead to it’s own self-destruction.
