Ahh that Germany lost the war in 1945 myth.
I ask you why the German Empire stretches from the Saar and Upper Rhine to the Düna an Dnjepr with a chain of allied states in the east of that. Emperor Georg Friedrich is also a Romanow, so could rightfully lay claim to the Russian Republic.
Wilhelm (III) was a different man from his father. After the lost first Great War he accepted that the HIGH SEAS had no place for Germany (well what is beneath the surface ...
).
It is the Army and airforce that win wars - so when the Army took Leningrad in 1943 and Moscow in 1944 it was only logical to make peace with the Russian Anti Bolshevik Coalition. With no chance to invade american backed Britain (at a reasonable cost) it was logical to ask for terms in the west...
Well resources poured into the Reichsmarine (other than sub raiders) might have translated in less tanks and planes when the Soviets attacked the Empire and its Polish allies...
