Okay in this ATL, let's say the Hitler and the German High Command realize around Oct-November 1941, they realize that the Soviet Union isn't going to collapse anytime soon as they saw, and halt their lines before even going upon the Soviet capital and then after improving the logistical situation and defending against Soviet counterattacks in the winter of 1941-42, they then decide to go for Stalingrad in OTL.
How would this change the Eastern front? Would this benefit the Soviets or the Germans? Is this a victory for the Germans, or does this shorten the the campaign for the Soviets?
