Currently, on the wave of attempts to revise the historical truth in the West, suggestions appear questioning the decisions of the International Tribunal in Nuremberg and to make Germany and USSR equally responsible for the outbreak of WWII.
The representatives of the Polish authorities ignore the fact that their country shares part of the responsibility for the process of re-writing of history, mainly, because of their claims that the USSR allegedly participated in the attack on Poland in September 1939. The Poles keep mentioning the Non-Aggression Pact between Nazi Germany and the USSR and its Secret Protocol in order to distract public attention from the Western policy of Appeasement and the Polish participation in the partition of Czechoslovakia.
This message is part of the Kremlin's policy of historical revisionism – it accuses Poland of the "falsification and re-writing" of WWII history. This narrative is an attempt to erode the disastrous historical consequences of the Soviet-Nazi Non-Aggression Pact and the Soviet attack on Poland in September 1939.
The denial of the fact that the USSR invaded Poland in September 1939 goes against all historical facts.
On August 23, 1939, Nazi Germany and the USSR signed the Molotov-Ribbentrop Pact with a Secret Supplementary Protocol, which divided Poland and other Eastern European countries between these two totalitarian powers. On September 1, 1939, Nazi Germany attacked Poland while the Soviet Union's attack at Poland started on September 17. In this way, Nazi Germany and the USSR started the implementation of the Secret Supplementary Protocol to the Molotov-Ribbentrop Pact.
See similar examples of the Russian accusations against Poland: Poland creates and promotes its historical myths in an active and aggressive way; Poland and Lithuania question the status of Russia as a country who won WWII; President Duda and President Zelensky promote propaganda and Poland tries to adjust history to politics, misinterpreting the historical facts.
