Well is there some way Germany could have won that maybe I am not aware of?
Well, just for giggles, imagine this.
On the eve of Barbarossa somebody plants a bomb at a 3rd Reich strategy meeting, and Hitler, Goering, Himmler, Goebbels, Raeder and Heydrich are killed. Milch, Doenitz, Galland, Rommel, and the general staffs of Wehrmacht, Luftwaffe, and Kriegsmarine survive and are now running the show. The mobilization to the east is written off as a "theoretical logistics exercise" while Ribbentrop makes nice-nice to Stalin and the non aggression pact is extended, freeing Stalin to chastise the Japanese for their activities in Manchuria. All the manpower and weaponry collected for Barbarossa is now available for reinforcing the Atlantic Wall, consolidating a secure supply of Libyan oil and eliminating Malta and Alexandria as threats to the Med as an Axis Lake.
With only one (well equipped) front in active combat, resources can now be freed up to pursue some of the tech developments that were backbunered by "blitzkrieg fever", such as jet fighter, submarine schnorkel, V weapons, Walther propulsion, airborne radar, remotely guided missiles, the "Skipjack style" streamlined high speed submarine, acoustic torpedoes, and nuclear research. With the Allies eliminated from the Med, and Suez in German hands, Britain is effectively at a standstill, and another "sitzkrieg" ensues on land, while the German surface navy is starved into a "force in being" which rattles its sword occasionally to keep the RN in Scapa Flow, but consumes minimal resources, while the Uboat Navy goes all-out, introducing ominous new technologies.
Pearl Harbor doesn't happen on schedule, as the festivities in Manchuria have taken the wind out of the sails of the "Southern Option" faction in the Supreme Council, and the conflict being a land war, puts the IJA in the driver's seat over the IJN, with resulting domination of the available resources.
Meanwhile, the US slumbers peaceably on, with isolationism and The German-American Bund gaining in popularity, the song "Ruben James" becoming ever more popular, and Roosevelt's "Anglophile" tendencies becoming more and more under attack.
So there's the world as it exists on December 31, 1941. I've laid out the blueprint; y'all have fun now, hear?
Cheers,
Wes
