It would have been better like this. Then Germany would be much cultural. That is how the TRUE 1989 German Re-Unification should have been. Who knows? Maybe Pommern, Schlesien (or at least Niederschlesien) and Ostbrandenburg will be returned to Germany, their RIGHTFUL country, one day.
These regions were built by Germans and populated by Germans. Germanic tribes lived there originally and were German lands until 1948 (though they had been lost before briefly but later re-taken by the Holy Roman Empire).
I'd actually approve of this. Germany is very culturally heterogenic, but if you'd split it that way, the cultures in the individual states would be more unified. Now the question is if that is a good or bad thing.
Yeah, France literally signed future Fall of Paris by Treaty of Versailles.
I would prefer Kaiserreich alternative timeline - with communist France and Britain, and fascist/antisemitic United States - Jews immigrating to tolerant Mitteleuropa And then, in Second Weltkrieg, German Empire will save the world or die trying
