A 47 year old man killed by the 72 year old president. Nothing shows the conflict of generations in Russia better than this. The old farts of Russia/Soviet Union are killing the younger generation and by that are killing Russias future. For what, grandpa? For what?
There simply aren't enough young men there to keep the Russian population growing and the population there doesn't value diversity enough to consider producing more Russian children with immigrants.
This is what many believe (e.g., Peter Zeihan) to be the real reason behind the invasion of Ukraine. Ukraine is "Russian enough" in their eyes, so combining the two populations would help stave off demographic collapse.
