Den of Spies: Reagan, Carter, and the Secret History of the Treason That Stole the White House

Thanks for the Google answer. The fact is that several people have confirmed that this happened on the American side, and on the Iranian side. There were others in Russia and Israel who knew about it as well. I'll recommend a book on the subject that covers it from beginning to end: https://www.amazon.com/Den-Spies-Reagan-History-Treason/dp/0063330601
