Your larger point is true (especially in more modern shows, post 70's sci-fi anime boom) but I think that's being a bit unfair to Gundam and Zeta- as much as Zeon is definitely commentary on Imperial Japan and fascism in general, the Titans and the corruption within the Earth Federation was commentary on how much it sucks to live under Post-War American Imperialism. I don't think he was trying to both-sides it.
