Also, I’d add that, while Russia is full of men, and technically the manpower is close to infinite, the equipment is a whole another story.
Government organized a lot of volunteer services to allow civilians to support the effort by donating clothing, collecting money to buy armor and even guns.
Many on the frontlines are constantly talking about critical lack of basic supplies, and drafting any more people is just sending them to sure death without any effect on the actual military effort the Russian government pursues. This is probably one of the core reasons Russia doesn’t escalate the conflict any more.
And yes - war is not popular here, but sadly, that’s something we mostly have to share quietly on our kitchens.
