After failing to take Moscow, the chances of winning went sharply down, but a resounding victory at Stalingrad would have still messed up the soviets logistically and morally; after all, its called Stalingrad. After that, the soviets might have been willing to sue for peace. Im of the opinion that failure at Moscow made victory for Germany very difficult to achieve, as the spritual and political center of the soviets remained intact, but Stalingrad pushed it over the edge, by saving the volga and boosting morale significantly. Kursk accelarated the defeat and ended any potential political leverage over the soviets, as well as giving them the definite strategic advantage.
