The dramatic secret history of the undeclared, ongoing war between the U.S. and Iran — the story behind the headlines.**

The United States and Iran have been engaged in an unacknowledged secret war since the 1970s. This conflict has frustrated multiple American presidents, divided administrations, and repeatedly threatened to bring the two nations to the brink of open warfare. Drawing upon unparalleled access to senior officials and key documents of several U.S. administrations, David Crist, a senior historian in the federal government, breaks new ground on virtually every page of The Twilight War. From the Iranian Revolution to secret negotiations between Iran and the United States after 9/11, from Iran’s nuclear program to the secretive and deadly role of Qasem Soleimani, Crist brings vital new depth to our understanding of “the Iran problem”—and what the future of this tense relationship may bring.

For anyone seeing a deep perspective on the ongoing conflict between America, Israel and Iran, The Twilight War is essential reading.
