Holy shit, this history lecture has now crossed the line from "uhh, I don't think that's quite right, and you've even got parts of the most widely-accepted theories wrong (steppe nomads coming to India from the west? That makes zero sense)" to absolutely hilarious, and the 4th fleet's admiral declaring that his secret plan relies on PURE ARYAN POWER to harness holy ancestry is so insane it's just funny now.
@Gunner1960
What's always amazed me about the Aryan Race Invasion theories is that all of this happened so long ago (something like 5-10 thousand years ago) and that ethnic group mixed with so many others afterward that it really shouldn't matter, although the Proto-Indo-European language group diaspora is an interesting curiosity of pre-ancient history. Might as well say the racial/ethnic groups associated with the Proto-Sino-Tibetan language are the ones who should have the 'holy ancestry', (or at least as big a claim to it), since they established a far wider spread in ancient times (and their linguistic/ethnic descendants weigh in at least equal if not higher than the Proto-Indo-European groups).
Wait a second.
That's actually something people believe about the ethnicity(ies) associated with the Sinitic language group's spread. And it's a Chinese author.
This suddenly makes a lot more sense if you substitute "Han" for "Aryan", and remove the specific country references from previous chapters. Particularly in terms of the Eastern spread that's been mentioned.
