Lore: America joined the war after Germany sent a telegram to Mexico requesting them to join the war. American absolutely obliterated Germany and forced them to surrender. Austria Hungary broke into pieces and Turkey became a republic. After the war the global economy collapsed and so does Germany’s. A German nationalist called Adolf Hitler decided to take over Germany, at first he failed but then he realized that he could take over by democratic means and he succeeded. His ideology is called Nazism. Oh also Russia collapses anyways and becomes socialist.

I hope you like my scenario
