I read the other day of a war game scenario the Russians conducted a few months back where they were gaming a Chi-Com invasion into Russia....They went tactical nuke in a bit less than three hours into it.
There won't be a repeat of Operation Barbarossa in Russia anymore without tactical nukes involved.....NATO better get used to that fact.

Here is the Wikipedia article discussing Operation Barbarosa.
What is interesting is that Russian military tactics have not changed much despite it being a losing strategy.
And the Russians then instituted the Holomodor (potato famine) afterwards. As if it would avenge....
What's really disconcerting is that the two sides of this conflict have entrenched polarization of their only way to resolution.
Russia does need the groceries, metals, and other resources of Ukraine for discounted prices. (Which is why they invaded Ukraine) Ukranians want their farms and homes back without Russian strong-arm, mafia style treatment in the global marketplace.
Russia wants an economic future which is better than they currently can have being not much more than a gas station. However they are extremely limited in a population size and technology that can make this happen.
They are extremely dependent upon everyone else in the world for most technologies. (Including petroleum refinement)
The Russians do have an oversized military infrastructure in military equipment from their decades of overspending to boost their economy. Instead of civilian infrastructure they spent the money on military. (Which has been stripped and sold on black markets...you used to be able to purchase Russian military night vision goggles and rifle scopes easily off the internet for discounted prices)
So....where Ukraine is wanting freedom from Russian mafia style influence and progressive European economic advantages and Russia wants global influence in the global economy....there can be peace without war. Nobody is really going to like it...but they can dislike it all they want but still be alive to dislike it.
Currently Ukraine is going to need decades to recover from this war. Russia has leveled many entire large cities. The mines require time to safely remove. Farmers need their equipment, farm houses, and land back. It's not going to be fully functional for 70-80 years if the fighting stops today.
And on a side note....as much as Elon fussed about letting Russia win his companies are a primary reason why Russia invaded to begin with. (Rocket engines and fuel are made inexpensively in Ukraine)
