So that's the idea behind it: A united Europe without one major European country within it isn't really a united Europe. While this is of course still true if Switzerland or Norway aren't within, united Europe would rather look like half of a Europe if any of the Top Four (UK, Germany, France, Italy) wouldn't be part of it.
This board has an ATL with a really alternate United Europe missing a country known as a fundamental part of OTL United Europe. The ATL is Weimar World, the ATL EU is the NEA, and the formentioned missing country is France which even got expelled from its own Francophonie in this ATL. And as France is outside the ATL United Europe, the NEA is still somewhat half of a Europe as you can see in the 1980's map.
So here comes the challenge: Make an alternate Weimar World with a France becoming part of the NEA during the course of the 20th century.
