Everyone in Russia knows about Allen Dulles and no one knows. Despite the fact that not a single work about him has been published in Russian, he is presented as the patron of the Nazis, the main enemy of the USSR, the organizer of a huge number of murders, including the attempt on the life of John F. Kennedy, the legendary master of espionage, a man who for many years stood behind the backs of the US rulers , effectively guiding their policies. Who was he? What role did this man of clearly remarkable talents play during the war years and in the post-war development of his country? How did he manage to turn the CIA into the most powerful intelligence agency in the world? These questions are answered by the authors of the book, which is based on documents from US archives, in particular materials from the US National Archives, the US National Security Archive, declassified CIA funds, the Dulles collection in the Princeton University Manuscript Library, documents from the archives of the libraries of F. Roosevelt, H. Truman , D. Eisenhower, J. Kennedy.
