This is the third and final book from the new project “Myths of the Molotov-Ribbentrop Pact” by the famous historian Arsen Martirosyan. It is devoted to a detailed exposure of the myths that surround the true history of the immediate conclusion of the Soviet-German non-aggression pact of August 23, 1939 and the events that followed. As in the previous two books on this issue, the little-known or completely unknown history of the Soviet-German non-aggression pact is shown in the analytical mode of intelligence-historical investigation. Particular attention in the book is paid to a thorough exposure of dirty fakes that went down in history as supposedly “secret protocols” to the “Molotov-Ribbentrop Pact.” Great attention is also paid to the analytical exposure of myths about the events of global significance that followed the conclusion of the treaty - from the beginning of World War II and the bloody tragedy in Katyn, for which they are trying to impose responsibility on the USSR and Russia, and up to Molotov’s visit to Berlin in November 1940. The book is full of interesting documents and facts, most of which are little known to the general readership.
