While we're on border anachronisms...
-Estonia is basically modern Latvia and Estonia
-Latvia is modern Lithuania
-Scandinavia is borders, post-WWII
-Ukraine and Belorus appear to have their current borders, which were determined by Soviet Administration
-Georgia and Azerbaijan appear to have their modern shapes, South Ossetia, Abkhazia, and Nakchivan notwithstanding
-Poland has post-WWII borders
-Iran aside, the middle east reflects the current world
Now, there could be justifications for this. Some of these borders could crop up in alternate timelines. But I don't see how they can exist when europe west of the oder is so different
-Politically, Linguistically divided Italy
-An occitan State from Valencia to provence
-A Spain where Castille predominates, but never finished the conquest; independent portugal and andalucia
-United Kingdom in Britain, sans Ireland but with Andalucia
-Venice and Milan united
-Strong Savoy; independent Sardinia
-Germany seems to be post-Anschluss, plus Sudetenland and half of the low countries
Again, these are in most cases doable, some of them in the same timeline. but I'm clueless as to how to get them all, especially with eastern europe following OTL.
