As many of you know, 80% of the Wehrmacht were stationed on the eastern front. And where did the Soviets decide to engage them? On the eastern front. If the soviet leadership had any regard for the lives of their soldiers, they would have engaged the Wehrmacht on the western front.
The funny thing is the Soviets DID try to attack the western front, by asking the British and Americans to enter the war as a second front against fascism. They were told to pound sand until D-Day.
