Oh, my sweet,
sweet summer child... They don't. I assure you.
How in the world does
this make sense? Also, I just noticed Sydney in Australia being replaced with a water-filled crater seems to be a constant in every Gundam Timeline. That place just seems to attract orbital drops like nectar does flies, doesn't it?
And then there is Seed, which is just as disappointing in its maps as it is in its story and worldbuilding, because it seems like the writers just copied the world of Orwell's 1984 (especially looking at the Eurasian Federation and Atlantic Federation situation in regards to Britain), but with a few extra borders for nations like India, Scandinavia (which looks like it revived the Kalmar Union out of a sense of nostalgia), and the Equatorial Union. The setting also seems to be oddly enamored with using "Union" for some reason. The only part of that that kinda makes sense is the Oceania Union, which is just Astralia and New Zealand, as the two nations have been pretty close historically.
I don't have a map for 00 at hand, but it's geopolitics are even messier, and with way more outlandish names to boot, with China, India, and most of Oceania, iirc being united in the "Human Reform League" (good fucking luck convincing your constituents and neighbors you
aren't a Dictatorship with enforced Eugenics if you consciously chose that name), North and South America falling under the authority of the "Union of Solar Energy and Free Nations", which is just a
mouthful, and the European Union, while occupying Europe as well as all of Anatolia, the Levant, and Barents Sea (the sea north of Russia, for those who don't know, and somehow felt the need to add "Advanced" in front of its name, becoming the "Advanced European Union", which is just unnecessary. Also, Japan is somehow still independent in that whole mess, as a "Special Economic Jurisdiction", because it wouldn't be Gundam if the stand-in for Japan isn't made somehow special in defiance of reality (looking at Seed's Orb Union here, which the writer said is meant to be his idealized version of Japan).
I Expect You To Die might not be much more realistic, but to say that the writers of Gundam put more effort into their geopolitics, at least when it comes to the nations on Earth, just isn't true. Well, or they put alot of effort into it, but the results are simply nonsensical. And the names for the Superstates are at least catchier, especially when compared to 00. I mean, "Union of Solar Energy and Free Nations"? "Advanced European Union"? That's right up there with "Galactic Federation of Free Alliances" of Star Wars fame in terms of how not to name something. The "Hudson Federation" and "Mediterranean Commonwealth" are much more believable as far as names go.
