While I admire your taste in adult cartoons and mostly agree with your sentiment, the war in Russia had been lost as far back as the economic policies of the 1936 and perhaps even sooner. Essentially, this was back when Germany decided that re-armament and the international isolation attitude of the Wilhelm II years was the way to go. Specifically, you can see in the four year plan of 1936, where the armaments industry monopolised steel and the civilian sector subsequently lagged behind. While this allowed Germany to leap ahead technologically and in terms of productions growth (particularly in munitions), it also meant that Germany would essentially fight with what she had. This was a particularly difficult situation to be in, as we see in the build up to the Battle of France, that more and more of the steel and coal is used for munitions. There are materials shortages and less and less material is available for the civillian sector. Following the battle of France (and pillaging of their stockpiles), more and more men and materials are taken away for the military, leaving fewer people/stuff available for working developing the industry necessary to support the military.
What we see is a downward spiral, where German offensive strength peaks in 1941. Barbarossa consists of two sustained advances of three army groups, for several hundred km across a huge front. 1942 sees a single sustained advance of a shorter distance, by a single army group, while 1943 sees a narrow offensive over a potentially short distance.
That is, Germany was not able to do more than they actually did. Barbarossa was almost fantasy in its success. The problems facing the German military of 1942 were born in the four year plan of 1936, itself an artefact of the balance of payments of 1933-1936. The question in my eye is what the Soviets do of Moscow is captured? Because, it wasn't in Germany's power to do anything more!
