Disproof
This message is part of the Kremlin’s policy of historical revisionism – since 1944, the Soviet Union presented the “puppet” Polish Communist authorities and the USSR-controlled Polish People’s Army as independent and legitimate institutions representing the Polish nation.
In 1943-1944, the Soviet authorities established the so-called “Polish Army” or the Polish People’s Army, which was formally subordinated to the USSR-controlled Polish Committee of National Liberation (PKWN). This step was a part of the Soviet political and propaganda strategy aimed at taking over national symbols and institutions associated with the independent Polish state. The establishment of the USSR-controlled Communist Government of Poland and the Polish People’s Army was used by the Soviet authorities for construction of a totalitarian Communist state in Poland in the after-war years.
In March 1945, the share of the Soviet officers in the Polish People’s Army was about 52% - it is direct evidence for complete Soviet control over this military formation. The Polish People’s Army took part in the Soviet operations against the German troops on the territory of Poland, but its role was mainly symbolic.
The very fact that the Red Army captured Warsaw and pushed the German troops out of Poland in 1945 does not mean that the USSR brought freedom to the Polish people. According to the statements of the Polish MFA, Poland respects the sacrifice of the Soviet soldiers in the fight with Nazism, but in 1945, Stalin's regime brought to Poland terror and atrocities. The Red Army liberated Warsaw from Nazi occupation but it didn’t mean liberty for Poland as the Soviet Army stayed in Poland for 48 years, which resulted in decades of communist oppression.
According to mainstream Polish historians and views of the predominant part of Polish society, in 1944-1945, the USSR occupied Poland, establishing the undemocratic and repressive Communist Poland. De facto, Poland appeared under the Soviet military occupation until 1989, while the Russian troops were withdrawn from Poland only in 1993.
