A world without Ahmadinejad

Ahmadinejad is very popular in the German media, apparently. This weekend, he chose Frankfurter Allgemeine Sonntagszeitung in order to announce that he would be interested in leaving politics at the end of his mandate.
I must confess that every time I have the patience to watch 5 minutes of an interview with Ahmadinejad, I can hardly follow him. I watch his eyes and it is enough to realize that I am not a psychologist enough to understand him. 
On the other hand, his announcement sent a strong message that he almost lost the battle with the religious establishment. Even though the two groups share the same toxic and hate driven ideas about the state of Israel and are oversaturated with anti-Semitism, their economic and political interest may divert. From many respects, until a certain level, Ahmadinejad was the puppet the regime needed in order to install its power over the country, including by using the Revolutionary Guards. But, money do not have colour and thus Ahmadinejad and the religious elites under the control and guidance of the Supreme Leader Ali Khamenei have an increasingly tensed relationship.
The departure of Ahmadinejad will not leave too many traces and unless the educated Iranians will be let free to take their country back, nothing noticeable will happen except a change of the faithful guard.
