the Third Reich was Adolf Hitler's empire, the Fourth Reich will be my empire. The Goal of the Fourth Reich is world peace.
Yeah, but since there was a Third Reich for you to rule the Fourth Reich and you confirmed it was run by Adolf, what happened to it? I as because you said you were using WWII era German ships and style yet very few of those ships survived the fate if the real Third Reich and those that did became short lived war prizes for the most part. On top of that Germany was a still occupied vassal like state divided in two for a significant amount of time after that. How does your AU handle all this?
Ps. I AM NOT A DICTATOR. I am just a militant self proclaimed world leader (that has almost reached his goal), who wants world peace and I am willing to fight for it.
That would be a dictator, or you could stylize it despot if you like.
