However, starting in the early 1910s we will start to see a divergence. It will start with Kaiser Wilhelm III deciding to govern without the Social Democrats anyway. It will also subtly diverge as some of the worse tendencies of the British Empire will begin to take ascendancy.
By the 1930s, we will see an Imperialist, repressive Anglo German Alliance facing off against the reformed Republics of the world, Russia, USA, France, China, etc.
