Everyone in Russia knows about Allen Dulles and no one knows. Despite the fact that no works about him have 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 John F. Kennedy, the legendary master of espionage, the man who for many years stood behind the rulers of the United States, actually directing their policy. Who was he? What role did this man of clearly remarkable talents play during the war and in the post-war development of his country? How did he 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 the archives of the United States, in particular the materials of the National Archives of the United States, the National Security Archive of the United States, declassified CIA funds, the Dulles collection in the Princeton University Library of Manuscripts, documents from the archives of the libraries of F. Roosevelt, G. Truman, D. Eisenhower, J. Kennedy.
