Is this satire?
Ukraine has been decimating Russian forces as effectively as anyone could have ever dreamed; there are more relevant ways to measure progress than hectares of land taken.
In what parallel universes is there an entity Ukraine could make an effective treaty with as long as Russia is intact?
As the saying goes, when someone tells you who they are, believe them. Putin has repeatedly broken every treaty when he found it convenient. Any treaty with him will be broken.
Any settlement of the war at this point would just allow Russia to rebuild and come back.
The Russian losses are massive, though not on the scale of the Russian/Soviet military losses during WW2. I think it's equally important not to overstate the weakness of the Russian military as it's strength. Realism is the best approach, imo. For the domestic consumption within Ukraine, a bit of optimism is probably good for morale.
You also have to look at the scale of the troops involved. In WW II, about 34 million people served in the forces of the USSR. 6.3 million were KIA. It's tough to find numbers on exactly the number Russia has committed to Ukraine, but it's probably in the ballpark of 1 million or less, and they have lost 360K dead with possibly another 100K or more who are maimed for life.
For the size of the forces committed, Russia's losses are worse than WW II.
