Looking at this, this is not a situation that is going to be resolved with war. What this is to me is an eternal meat grinder; each side can simply fall back to safety, regroup and rearm. Russia cannot outflank Ukraine without stepping on NATO toes and they wont risk going in too deep and Ukrainians cannot outflank or end this without destroying all of Russia. This is a war of attrition is what this map is. They need to both stop ****ing around now and come to the table instead of dragging this out. This can go on for decades.
Ukrainians obviously want their country, all of it. Russians have no right to be there. If someone breaks into your house and says he is taking your bathroom, you don't just say OK, you can have it, just stop hitting me.
