Iran's nuclear ambitions, born under the shah

But in his new book, "Iran and the Bomb," author Sina Azodi traces the country’s nuclear program to the early days of the Cold War. Azodi joins The World’s Host Carolyn Beeler to discuss the long complex history of Iran’s nuclear ambitions, and argues that knowledge of how to build a nuclear weapon “can’t be bombed away.”
