> Not at the end. Also back then US had USAID

1960s and 1970s are the end to you, really? USAID, really? You have already proven that you have a very remote understanding of Russia/USSR, please stop trying to bring this point even further.

> I think you are not qualified to say that.

I actually am.

> Talk to more yakuts who live in the "center".

By pure chance, I do have such contacts, they laugh at this decolonization crap. Also by chance, I knew Russians who lived in Yakutia in 1990s, and they did tell me stories of discrimination from the locals. Same as stories of discrimination of Russians in Kazakhstan, Baltic republics, etc -- both in soviet and post-soviet times.
