Like some of his economic ideas, Keynes was full of crap about the Versailles reparations.

Versailles was France’s revenge for losing the Franco-Prussian War.
I disagree with the Federalist on this. Not just the repairs but the whole Versailles Treaty seemed calculated to cause another war. Which, is exactly what it did. Germany did not start WWI. It was not seeking to dominate Europe or indeed any territorial aggrandizement.
