You are drawing a Hitler or Napoleon on to Wilhelm.. There is no monomaniac tendency from Wilhelm - yes he would like to be a more absolute monarch but even then he recognises he is one of several monarch all with an equal right to exist. Not the supreme leader of Aryan civilization as Hitler saw himself. There is no divided France in front of him and a fig leaf of liberation philosophy to justify occupying swathes of France as Napoleon did to Germany.1 - still they have dealt with France in less than a month so they will be high on their own success and the temptation after this to redraw the map of Europe can be too strong for Willy and co. as frankly if they want there is nobody that can stop them. Frankly they can just adapt the Septemberprogramm and go with it. Oh they have more important thing than the Flanders, Belgium neutrality has become a joke, any british analyst will thought that Bruxelles capitulated only with the slightest German pressure when there were also France to consider, but now with Germany the only game in town there is no way that they resisist when Berlin demand something, hell they don't need military power just the economic one.
2 - the problem is that in this situation, Germany can get away with everything they want, France is down and the British don't have any mean to relief them, Serbia will be soon over and Russia is on the same road...the other big power in Europe are allied with her, so it's covered. Belgium will be a little nice boy and do what mama Germany say, there are already German troops there and anyone understand that the Belgian army is not a factor plus permitting the Germans passage had burn a lot of diplomatic bridge and being surrounded by now dominant reich will do the rest
After the long peace of the 19th century we have again what used to be called a "cabinet war" - a quick war fought to established diplomatic preeminence. Yes German has had to fight France twice in 50 years - this is normal for a European rivalry. Just look to GB vs France in the 18th century. Wilhelm knows full well he can't destroy every other power in Europe. There is no "war to end all wars" meme in existence yet. The peace treaty will seek to economically and diplomatically secure Germany as the preeminent power in Europe - at least for a decade or two. it won't be a naked power grab. Germany will be preparing for the next war as soon as this one ends.
