As part of a series of conversations marking 1979 as a seminal year in the Muslim world, Steve Inskeep talks to Iranian-born journalist Kasra Naji about the Islamic Revolution. Naji was a student in Iran at the time and has been in and out of the country since then. He's a special correspondent for BBC Persian Television in London. He also is the author of Ahmadinejad: The Secret History of Iran's Radical Leader.
