For all his many flaws the Kaiser was not hell-bent on conquering Europe, except maybe in a fancy day-dream.
Even the French had come to terms with 1870. Revenge was not on the political agenda around that time. It had been put on the back burner as more pressing concerns accumulated over five decades.
Nobody in Europe desired another war, but nobody was going to avoid a fight should it happen.
The original plan was to address the matter in the Balkans with a bit of sabre-rattling or maybe a brief war to teach the Serbians not to meddle in the affairs of major powers.
A few weeks later armies marched against each other all over Europe.
Plans of battle had been drafted and re-drafted, but the outcome and aftermath was left for diplomats to decide. Germany certainly had a list of things it could benefit from should they be victorious.
I cannot stress enough how common reparations were in those days. Versailles has often been described as an aberration, though it was merely standard practice for centuries before.
A German/Austrian/Ottoman victory over France/Russia would have serious consequences. Germany would probably annex parts of coal-rich Belgium and France to fuel the industry and carve away at the Belgian Congo and French Colonial Africa. What's left of Belgium would probably end up being a German protectorate or lumped together with the Netherlands.
We would see German gains in Russia and the Ottomans and Austrians carving away at the Balkans, the Black Sea and the Caucasus.
It would stabilize these nations for a while longer until they eventually implode somewhere down the line.
France would probably be deeply divided politically, the perfect opportunity for a strong figure to emerge at a time where the leadership and structures of the République are in question.
I have serious doubts that even a "benign" German domination of Europe would go down well. We might get a kind of European integration, but with Germany dominant it would be on unequal terms, mostly for the glory and benefit of Germany first.
It may take a while, but sooner or later Europe would go to war, depending on how the situation evolves the US will become a decisive factor in determining which side wins. If Germany becomes a major trade partner and the coalition against Germany appears too bellicose …
Germany winning in 1914 doesn't resolve anything. Europe was a set of tectonic plates that had been pushing against each other since Vienna. WWI didn't resolve this problem and a French collapse in 1914 doesn't either.
Europe changed after four years of bloody battle in the Trenches with most of the monarchies collapsing, but it took another World War to really change minds.
A France defeated in 1914 does not change the mindset, we still have the Kaiser and his personal demons, the dying Russian, Austrian and Ottoman empires. It's another 1870 and no real resolution other than that Germany becomes too powerful to some and France is further weakened.
Europe needed a 500-year long civil war to finally understand the need to put the rifle and sword away when dealing with each other. It started in the 1500's when the first states were centralized all the way to the Wagnerian finale of Hitler's mad genocidal regime.
Yes, there was a concept of a German-led European Economic system but that would have been at best a one-way street even in its more benign form.
At best it leaves France bitter and unwilling to cooperate at any level, a Britain having to contend with possible German expansion and it leaves the question in the air on which side the USA would end up supporting. A Germany playing the card of stability in Europe against the British and their ambitions and the perpetually resentful French …
