His already financially strapped country is losing a ton of money every day they continue this battle. Who knows how their military is handling covid? Their country is dealing with omicron right now, their vaccine didn't seem to do very well, despite their claims....Hong Kong is a disaster right now, I cant imagine what the Russian army might be dealing with....
The last thing putin needs is to level the country, if he does take it over he wont have any money to rebuild it. To top it off, a majority of the world is going to boycott anything coming from Russia....It really doesn't seem like putin cares anything for his own country at this point.
