Pajamas Media has an especially hilarious post by The Manolo discussing the styles and fashions of different dictators. He finds that Ahmadinejad may be lacking:

Briefly and remarkably, the President of the Iran wears the same khaki windbreaker, wrinkled trousers, cheap oxford shirts, scruffy beard and wild eyes favored by the aging high school chemistry teachers everywhere.

Yes, in his youth he was the firebrand who would shake the very foundations of the society, but today he is content to expound upon his paranoid conspiracy theories while exercising his petty autocratic powers over the dull kids who sit in the back of the class.

In the word, he has tenure.

He also comments on Fidel Castro, Saddam Hussein, Kim Jong-Il, and Mu????????amar al-Qaddafi.
