The United States and Iran have been at daggers drawn for more than thirty years. While this rivalry has never erupted into open war, it has been an enduring “twilight war” in which spies and terrorists often play the lead role. US Government historian David Crist will discuss his groundbreaking book which pulls back the curtain on many of the deepest secrets of this lethal struggle. Among other fascinating revelations, hear about the massive spy network that the CIA developed in Iran with German help in the 1980s, how these spies communicated with their handlers using invisible ink, and how their discovery led to the deaths of more than two dozen people. This event took place on 1 August 2012.
