If USSR had lost to Nazi Germany?

What if, during the landing and first couple weeks after the Dday landings, Nazi Germany would have somehow broken through in Leningrad and somehow captured Moscow or forced the Russians to surrender and they were defeated. With this Allied force now in France, could they still push all the way to Germany on there own before alot of Nazi soldiers were taken from the Russian front to the western front? Would the Allies even still push on?

Not to create another topic, but another senario if what if the Dday invasion was a failure? This would be a huge moral blow, and would the allies consider another attempt at an invasion? What would the Russian responce be to this?

The Allies will probably pushed back simply because if you everview the battles on the West you will probably see that the Alles have prety much trouble even with the pittiful forces that the Germans had deploed.Now imagine only if the half of the easten front army visit the west,not only that but it won be so easy now for the Allies to control the skies cuz Luvtwafe (not sure about the spelling) will return from the east.Plus in case USSR defeated probably there must be some kind of reparations for the Axis,these reparations will refresh Germany war machine.With Russia out of the war Germany easaly can push back the allies both from normandy and Italy

The only way for Nazi Germany to have defeated the Soviet Union was Japan's invasion of the Soviet Union rather than initiating war with the United States. The Soviets had a powerful force on its eastern coast, anticipating war with Japan, and sent all of this west when it was sure that Japan would not attack. Have the Soviet Union fight on two fronts, spreading out its forces, then it would be defeated.

100% correct.
