I've only read about the postwar occupation of Germany in passing, so correct me if I'm wrong on anything here. Was breaking up Germany into smaller states that couldn't threaten Europe in the future ever on the table in 1945?
I know that West Germany was formed because the Allies wanted a buffer state between them and the Pact, but let's say the Soviets had occupied either all or none of Germany. Was there any point where breakup of Germany was suggested?
From the Teheran Conference, here are FDR's proposal (which as he acknowledged was "merely exploratory") to break up Germany and Churchill's proposal to separate southern Germany from the rest of Germany and make it into part of a Danubian federation. (The latter idea probably had very little chance; as this transcript indicates, Stalin was firmly opposed to it.)
***
Roosevelt: The question of Germany.
Stalin: What are the proposals on this matter?
Roosevelt: The partition of Germany.
Churchill: I am for partitioning Germany. But I should like to consider
the question of partitioning Prussia. I am for separating Bavaria and the
other provinces from Germany.
Roosevelt: In order to stimulate our discussion on this question, I want
to set forth a plan for partitioning Germany into five states, which I
personally drew up two months ago.
Churchill: I should like to stress that the root of evil in Germany is
Prussia.
Roosevelt: I should like us to have a picture of the whole before we speak
of the separate components. In my opinion, Prussia must be weakened as far
as possible, and reduced in size. Prussia should constitute the first
independent part of Germany. The second part of Germany should include
Hannover and the north-western regions of Germany. The third part --
Saxony and the Leipzig area. The fourth part -- Hessen Province,
Darmstadt, Kassel and the areas to the south of the Rhine, and also the
old towns of Westphalia. The fifth part -- Bavaria, Baden, Württemberg.
Each of these five parts would be an independent state. In addition, the
regions of the Kiel Canal and Hamburg should be separated from Germany.
These regions would be administered by the United Nations, or the four
Powers. The Ruhr and the Saar must be placed either under the control of
the United Nations or under the trusteeship of the whole of Europe. That
is my proposal. I must add that it is merely exploratory.
Churchill: You have said a mouthful. I think there are two questions: one
-- destructive, the other -- constructive. I have two ideas: the first is
to isolate Prussia from the rest of Germany; the second is to separate
Germany's southern provinces -- Bavaria, Baden, Württemberg, the
Palatinate, from the Saar to Saxony inclusive. I would keep Prussia in
strict condition. I think it would be easy to sever the southern provinces
from Prussia and include them in a Danubian federation. The people who
live in the Danube basin are not the cause of war. At any rate, I would
give the Prussians harsher treatment than the other Germans. The southern
Germans will not start a new war.
Stalin: I do not like the plan for new associations of states. If it is
decided to partition Germany no new associations need be set up. Whether
it is five or six states, and two regions into which Roosevelt proposes to
divide Germany, this plan of Roosevelt's to weaken Germany can be
examined. Like us, Churchill will soon have to deal with great masses of
Germans. Churchill will then see that it is not only the Prussians who are
fighting in the German Army but also Germans from the other provinces of
Germany. Only the Austrians, when surrendering, shout "I'm Austrian", and
our soldiers accept them. As for the Germans from Germany's other
provinces they fight with equal doggedness. Regardless of how we approach
the partitioning of Germany there is no need to set up some new
association of Danubian states lacking vitality. Hungary and Austria must
exist separately. Austria existed as a separate state until it was seized.
Roosevelt: I agree with Marshal Stalin, in particular, that there is no
difference between Germans from the various German provinces. Fifty years
ago there was a difference but now all German soldiers are alike. It is
true that this does not apply to the Prussian officers.
Churchill: I should not like to be understood as not favouring the
partition of Germany. But I wanted to say that if Germany is broken up
into several parts without these parts being combined then, as Marshal
Stalin said, the time will come when the Germans will unite.
Stalin: There are no steps that could exclude the possibility of Germany's
unification.
