It is possible that the Germans could move most of their forces to the West if they capture Moscow and force the Soviet Union to surrender. With the Soviets no longer fighting them on the Eastern Front, the Germans can focus on defeating Britain. They may be able to capture London. They would also be able to better defend against a joint Anglo-American attempt to liberate France.
if the germans can force the soviets out of the war.. this is a war of ethnic survival..Moscow is a great objective, but its certain doom and gloom as I am certain there wouldn't be much of Moscow left if the germans manage to take it. Nothing better than winter in Moscow in ruins.
as the ops stated .. barbarous goes off as planned. they are not getting Moscow, let alone keeping it with out protecting the flanks.
the germans actually respected the west.. well let me rephrase that.. the respect people they thought they could do business with. in the east they were willing to overlook things in places as well.
the thing is, there is no way, short of reverse genocide that the germans are going to fear the west more than the soviets
