But basically the status quo is that these areas would be no good for Ukraine anymore because they're shot to crap and full or armed rebels (or green men). It's not like it's actually useful territory for building housing or running commercial activities etc. It's also pretty clear Russia would keep playing that game even if they retreat.
I would assume they'd gladly give up this territory (and Crimea) at this point for the war to stop. And then go full NATO or at least EU for future protection. I don't think Russia will ever give up the war without some kind of compromise because they would lose face.
Either way, I hope a consensus will be reached soon because this BS war is killing real people.
