People tend to compare in this thread napoleonic France to Imperial Germany, how the Entente should treat Germany the way the anti-napoleonic coalition treated France at the Congress of Vienna. But you forget one thing: it was France the one who managed to get for itself the comfortable terms at the Congress of Vienna. Or should I say, the diplomatic brilliance of Charles-Maurice de Talleyrand, who managed to present France as "the first victim of revolution" and buy for France the comfortable terms by cutting off any connections to bonapartism, especially its expansionist aspect. That's what allowed France to be treated well. Germany on the other hand, lacked this kind of diplomatic attitude.
I think Germany could get for itself the comfortable position, if the Germans too play the Talleyrand-like gambit. After the Russian Empire was out of the war, Germany's main enemies were democracies either parliamentary monarchies. So if we ignore the minor players like Serbia, the war became de facto democracies vs monarchies. If Germany blames the war exclusively on Wilhelm II the way Talleyrand blamed exclusively Napoleon, this could've worked. But only if Germany proves its good intentions by renouncing any demands for itself, something which was hard to imagine due to the way Germans felt themselves to be special.
