Explanation
The losses of Germany on the eastern front are widely believed to be the most significant factor in defeating Nazi Germany and the USSR won the battle of Berlin, the final battle before the German capitulation. Thus Europe widely believed (for a good reason) that the USSR was the main contributor in defeating Germany. With the cold war the perception of the USSR became a lot worse in western countries like France and with increasing anti-USSR sentiment the view flipped to viewing the USA as the deciding factor. The USSR (and the Russian Federation today, even if its government is very anti USSR) viewed itself as the most important force in defeating Germany, especially because the USSR had the biggest amount of deaths. It is worth noting that the USSR was at least commercially allied with Nazi Germany until June 22, 1941 and there was an agreement between the nations on which parts of Europe each could invade and which where reserved for the other.
For its many mistakes, the USSR didn’t pillage the resources of any country, the only argument you could make in this direction are postwar reparations against Nazi countries such as Hungary. After 1955 especially, the trade policy inside the COMECON was one of the USSR supplying raw goods at subsidized prices in exchange for industrially manufactured goods. This policy is detailed with numbers in Robert C. Allen’s “Farm to Factory” and Albert Szymanski’s “Human Rights in the Soviet Union”. What’s your data source for claiming the Soviet Union pillaged any country?
Oh boy.
Poland was conquered by USSR against their will (well. More like betrayed by British and given to USSR)
Looting and plundering: https://en.wikipedia.org/wiki/Looting_of_Poland_in_World_War_II#%3A~%3Atext=The+looting+of+Polish+cultural%2Cworld+and+returned+to+Poland.
Industrial plunder is confirmed by then internal notes and memos, that the Poland under occupation later tried to use to convince USSR to stop because they already plundered a lot, so it’s not a CIA propaganda or smthing in case you’re wondering.
Betrayed or at least with their blessing. The Curzon Line, which was the Entente plan after WW1, was reaffirmed before and after the German invasion. The territory Poland annexed in 1921 was effectively ‘returned’ to the USSR.
Considering that one British MP resigned saying he cannot stand that shameful betrayal and the British internal propaganda surrounding that decision, the word “betrayal” fits like a glove.
In their memoirs (from a non-public meeting Churchill ordered to explain this to the MPs), some MP wrote that Churchill argued on country being tired of war, and that they have 100k (or 300k, I don’t remember) young Polish men that can repopulate the villages - why would they let them go.
God I hate that old racist.
