Veteran foreign correspondent Scott Anderson, who's written for the New York Times Magazine, Vanity Fair and Esquire, has a new book, King of Kings, about the fall of the Shah of Iran and the rise of the ayatollahs in 1979. He opens with a big claim: that the Iranian revolution changed the world as much as the revolutions in France, the United States or Russia. He tells Paul about the failure of two leaders — the Shah and President Jimmy Carter — to understand what was happening in Iran.
