resident /m/ fag here, I can explain. Zeon's Aesthetic and what Gihren's ideal political structure for the Principality was meant almost entirely to represent Nazi Germany, However, it would be a stretch to call Operation British a reference to the Atomic bombs, as Zeon and the Earth Federation both used massive amounts of Nuclear and Biological weapons. This would lead to Half of Humanity being wiped out within the early months of the War. The Principality of Zeon is a perversion of what Zeon Zum Deikun wanted for spacenoids as it was lead by a fat retard and his 4 fuckhead Children, however, Zeon itself is shown to have good people within its ranks, and this is shown within most OYW based media. The Earth Federation is def supposed to be a Hybrid of the US and Japan, albeit the flag is just the Brazilian flag. The Earth Federation is hardly any better than zeon, they are corrupt from the top down, but they don't really have a desire for space genocide as much they just wish to keep the earthnoids as the Ruling class. 
TLDR: Zeon is supposed to be inspired by Nazi Germany but not exactly be them, the Earth Federation is inspired by the US and Japan, but They're both fucked up and corrupt in some way. 

thanks for letting me Sperg about Gundam lol
