What if the Soviets and the Western allies agree during or after WW2 to withdraw from their occupation of Germany by 1948 allowing Germany to be a single independent neutral nation (like Switzerland) with a military no to be larger that 600000 strong with 450000 being army
I mean, this is basically the post-WW1 set-up, only this time, the Germans are geting a rather more sizeable army in the process. By doing this, the Western powers would have basically learned nothing, and merely put conditions in place allowing for round number 3.
The German army geting rebuilt in OTL was quite controversial, both East and West, as was the German reunification itself. Why would the victorious powers, that just lost millions of men puting the Germans down, now decide that immediate reunification, and strong rearmanent is a good idea?
Also, why would you just give up a valuable part of your sphere of influence? Both East and Western Germany were valuable parts of their respective pacts and spheres. Why just give up a valuable ally?
