Here's a couple of things I dislike
South American/Pacific Union/South African Control of parts of Antarctica (Would violate a number of international agreements, which with the Sol Alliance as the successor to the U.N. I would think unlikely)
Scandinavia Included in the European Union. I just don't like this, a Scandinavian political union is better in my book.
Japanese Control of those parts of Siberia. Japan is demilitarized (And the public is strongly in favor of this state) So, they wouldn't exactly have an opportunity to seize those parts of Kamchatka and Siberia.
Russian inclusion in the EU. Yeah, this is just never going to happen. I really hope I don't have to explain this one.
And a note, If you're going to make Catalonia/Galacia independent. I'd really like to see Vasconia/Occitania/Brittany/Venezia as independent parts too.
P.S. I fucking love you for adding Chechnya as an independent part of the EU though.
