Answer:
Russia paid a terrible price, it is true.
BUT, and this is HUGE BUT, you have to remember that they were pretty much the only ones responsible for making WWII possible. No one seems to remember it, but the signing of the Soviet-German Non-Aggression Pact on August 17, 1939, paved the way for Hitler to start the war 2 weeks later. Hitler and all his generals were opposed to a two-front war. If the Soviets had supported Britain and France, Germany would have been contained and Hitler would never have attacked.
Stalin's secret agreement with Hitler is directly responsible for the attack on Poland.
Second, if Britain and France had attacked Germany as soon as the war began, they would have found Germany's western defenses totally unprepared for an Allied offensive.
If you read about this in the history books, the German army was very scared that France and Britain would attack as soon as they declared war, and with almost all of Germany's military force in the east for the Polish campaign, it would have been a big problem. very short war. In the military stories, you will find that the Germans were not celebrating victory in Poland, they were holding their breath to see what was happening in the west. Most of the German military could not believe that Hitler had actually succeeded. The Germans did not become arrogant until after France's defeat in June 1940, when they felt that the threat to the western borders was over.
