Of course at the time of the fall of Berlin the Soviet armies were the overwhelming dominant military force in Europe but that equation entirely reversed only a few months later with the detonation of the atomic bomb on Hiroshima. Now the balance of power (assuming the production of a few more bombs by the United States) was entirely in favor of the United States who were in exclusive possession of that weapon until the Soviets exploded their version in 1949. During this window no attempt was made to bring the Soviets to account for their war crimes, indeed, no intent was made to free the slaves and satellite states of Eastern Europe who came under Soviet occupation.
At the time of the fall of the Berlin wall in 1989, no attempt was made to bring the communist regime in German Democratic Republic to the bar of justice for their crimes. At the time of the fall of the Soviet Union no such effort was made.
There is undeniably a double standard when it comes to the crimes of the left as opposed to the crimes of the right.
The victory of the Soviets of The Great Patriotic War was not a victory of a lesser evil over a greater evil but of one kind of evil over an another kind of evil.
