France wanted Germany to be seperated into single states. Of course, Germany would only accept so much. True, it didnt have any military chance anymore after the dearment of the initial armistice, but rather then accept dissolution, Germany wouldve fought on. The allies would then have won, but it would be a very messy and dystopic Europe, in which the allie swould have to occupy Germany, and in which probably communism has a much greater pull. All in all, GB and USA knew why they didnt agree with France...
Utterly impossible, dividing Germany at all will be hard enough, not to mention that not even the most revanchest of the French even thought of going that far
