The USSR contributed greatly to World War II
In recent days, I have been oversaturated with attempts to revise the history of the twentieth century on several television channels, some of which are even considered 'serious'. Precisely because of this, I would like to present a few facts for less informed citizens.

TL;DR
- Criticism of historical revisionism concerning the USSR's 20th-century actions.
- In 1939, after the Molotov-Ribbentrop Pact, the USSR attacked Poland, followed by Finland, and in 1940, Lithuania, Latvia, Estonia, and Romania.
- In 1941, the USSR began fighting Germany, its former ally.
- By 1945, the USSR directly occupied Lithuania, Latvia, and Estonia, and indirectly influenced Poland, Czechoslovakia, Romania, Hungary, Bulgaria, and almost Yugoslavia.
- The author states that revision is unnecessary.
