You may be right. However, Russia will preside over a wasteland, with nothing to show for it but a ruined economy.
No western company will invest capital or technology in Russia for decades. The education system foundered back in the eighties.
The ruble is toilet paper. Russia is paying for imports with gold and barter. It is shut out from the world's financial systems.
The Russian demographic is already collapsing, every soldier killed in Ukraine is one less contribution to population growth.
The current men to women ratio is 87 men, 100 women.
I understand the term is "Pyrrhic victory".
