Just working up ideas for a new TL and part of the idea I have is an early entente victory in WWI due to various reasons. Thinking over such a scenario though, I can't really imagine things coming off too well for the Central Powers aside from maybe the Ottoman Empire... ish.
You'll still have France wanting revenge for the Franco-Prussian War and the need to cut down on German strength. Plus in this scenario, Russia will still be standing and want its pound of flesh, most likely in the form of German Poland or something. Due to fears over the strength of Germany rising again, I can easily see another War guilt clause and limits on their Military strength. One way they might get off easier is reparations, two less years of conflict might help in this regard at least.
As for the other Central Powers (Or those who fought on their side), Austro-Hungary could very well collapse with Serbia getting everything it wanted while the Ottoman Empire might just give up the fight to pull through although I can see it surviving, barely albeit with Britain and France getting even more influence in the Middle East.
Your thoughts?
