Iranian Revolutionary Guard member Reza Kahlili was appalled by what he saw from the radical Muslim leadership in his nation nearly 30 years ago. So he kept his job but began spying for the CIA.

What brutality have they committed? What is their relationship to terrorist groups and even the Lockerbie bombing? And what does he envision if Iran fully develops nuclear weapons? Listen here for his insider analysis of this major threat.
