The letters of Mohammad Nourizad are now known and counted by their numbers - now only five, then 10, and by the end of 2011 they had amounted to no less than 15. These letters are written and published publicly to the Supreme Leader of the Islamic Republic, Ali Khamenei. The reaction of Iranians to these letters all comes together to mark a critical passage in contemporary Iranian political culture with ramifications for the region at large. Nourizad publishes his letters initially in his website, and from there they go viral - millions of Iranians around the globe read them, jaws dropping in admiration of his courage, his diction, his tenacity. He pulls no punches.
