All of these bizarre partition maps miss the basic point of how Germany got unified in the first place—through Prussia, one of the strongest German states, dominating and in some cases conquering the others. This meant that Prussian militarism was a legitimized as a core institutional value of the new German Empire. The Allies might have been able to turn back the clock after WWI, but twenty years later is a long time for a unified German national identity to entrench itself. Thus, it would be extremely likely for one of these new states to attempt to repeat Prussia’s feat, and whether or not they succeed, you’re looking at years of bloodshed and maybe even another world war. The Allies weren’t blind to this fact either, and aside from reversing the Anschluss of Austria (as it was one of their earliest grievances against the Nazi regime), they engaged in a reconstruction project with the primary goal of removing the influence of militarism and Nazism as much as possible, not keeping the German nation subjugated while addressing none of the core factors that led to its aggression in the first place.
