This question has probably been asked many times, but I haven't seen it yet so I thought I might as well see what you all think.
What do you think would happen if WW1, as we know it, does not happen? Lets say that the Great War is delayed until the mid 30s. How would the nations of Europe and the world look like? How would the German Empire, Austria-Hungary, Imperial Russia and the Ottoman Empire develop with an extra 20 years?
