So, not really an AAR, but still fun I think.
I expanded Germany so that I now borders Poland, Ukraine, Turkey and Sweden.
Inside my territory and not at war with my are Luxembourg and Kosovo.
Thanks for not having occupied us this time!
(unlike during WW I and II)
edit: Holy crap: 12.03 M soliders ....good job!
Moreover I would say: to rule all of Europe (geographically speaking), you need to attack the Russians and occupy Western Russia (right up to the Urals (Riphean Mountains))
Furthermore, you need to occupy Poland, Iceland and Eastern Europe, the Balkans, the Baltics, Scandinavia, and of course the European part of Turkey (up to the western side of Istanbul)
