The book is devoted to the study of the project of the American intelligence services to introduce into the mass consciousness the myth about the existence of certain secret protocols, allegedly signed by Molotov and Ribbentrop on August 23, 1939, simultaneously with the conclusion of the Soviet-German Non-Aggression Pact. The topic is considered by the author in a broad manner. Here is an overview of the pre-war foreign policy situation in Europe and the reasons for the conclusion of the Non-Aggression Treaty and the stages of introducing falsified protocols into propaganda and scientific circulation. Based on the transcripts of the Nuremberg trials, the author examines the question of the primary sources of the myth about the secret Molotov-Ribbentrop protocols, conducts a textual and documentary analysis of the canonical version of the protocols and their variants in circulation. The general reader will be very interested in learning about who and why began to introduce the myth of the secret protocols in the USSR. And also by whom and for what purpose was the confession, humiliating for the country, of collusion with Hitler extorted. The attempts of modern officials and historians to fabricate the “original” protocols, allegedly found in 1992 in the archives of the President of the Russian Federation, have been exposed. The book also contains portraits of the main propagandists of this myth (Yakovlev, Wulfson, Bezymensky, Herwarth, Churchill).
