American and British authorities have not always told the truth in the past, have not always correctly described what happened. Remember all their claims that the Russians shot down the Malaysia Airlines plane over Ukraine.
The shameful and Russophobic resolution of Polish politicians on the equal responsibility of the USSR and Nazi Germany over the outbreak of WWII once again confirms the fact that the current Polish authorities openingly falsify and revise the history of WWII, they are waging the information war against Russia.
This message is part of the Kremlin’s policy of historical revisionism. It accuses Poland of “the falsification and re-writing” of its history. According to this policy, the official Russian historiography is the only “true” way of interpreting the historical events of the countries of Eastern and Central Europe. On January 9th, the Polish Parliament adopted a resolution “condemning the provocative and untrue statements by representatives of the highest authorities of the Russian Federation attempting to hold Poland liable for the Second World War”.
See similar examples of the Russian historical revisionism concerning Poland - It is thanks to Russia that Poland today exists as a country, Nazi Germany considered Poland its best ally, USSR was forced and reluctant to sign Molotov-Ribbentrop pact.
