>>Russia also has its own version of the disastrous Chinese population implosion...
That's been going on since Stalin forced peasants into collective farms. No privacy = fewer kids. Then WWII took out a lot of people (mostly men) who otherwise might have parented Boomers. Trying to win a war by drowning their opponents in 'Russian' blood isn't new with their invasion of Ukraine. (I've put quotes around 'Russian' as they've also tried to use conquered peoples for the blood - also not new. )
