The Soviets pretty much shipped their infrastructure beyond the Urals. Taking Moscow militarily would have been of minor consequence, but again, it may have had a huge impact in terms of Stalin keeping his power.
The USA no longer has that option as we pre shipped our industrial base to our enemy already. Free traders sold us out.
I wonder sometimes if they had pursued Fall Blau in 1941 instead of 1942 whether the Germans wouldn’t have won. They would have captured all that industry before it could be moved, as well as any harvest from Ukraine and 40% of the Soviet Union’s oil.
