And personally, odds of a Space Reich existing aside, I think it's a good plot device simply for carrying through a theme of the series, which is presenting democracy and autocracy not as good and evil, respectively, but demonstrating the benefits and drawbacks of both. Sure beats the heck out of Gundam when it comes to presenting both outlooks as morally gray.
War and Peace in Space is a good one sentence description.

I agree that it's a lot more nuanced than most series, and well worth the investment in watching.
