They broke the back of the german army with the big help of the US who sent millions of tons of materials, weapons etc. to Russia.
It is a shame that the russian war criminals, criminals against humanity were also judges at the trial of Nurenberg instead of sitting near the german criminals.
Today we see the non-stop mistakes the west has done from 1945 to today and we are going to pay the price, especially Europe.
I guess in the next few years a war NATO vs Russia will start or at least Europe vs Russia if the US will leave Europe alone to face Russia.
