The historical letter that caused the predicted collapse of communism and brought about the inevitable changes inside the Soviet Union. This small booklet accomodates the very divine message that the leader of the Islamic Republic of Iran during the end of his blessed life wrote to President Mikhail Gorbachev. The main part that makes this booklet a classic are the efforts of the editor. He has painstakingly explained and described the various terms and people mentioned by Imam(ra) over the course of the letter in the footnotes. For example, The Arch Satan, Peripatetic Philosophy, Al-Farabi’s biography and so on.
