Inspired by some Franco-British Union, how can we have Russia and Germany unite into a single political entity?
How can this union works? What will its official language be?
And where the capital would be? My guess is Petrograd/Leningrad/St. Petersburg since it's midway between Berlin and Moscow, but that's me
The POD is 1900, of course, but bonus point if you can make Nazi Germany and Soviet Union unite!
Thanks in advance!
