Peace on Russia’s terms: they keep all territory currently held or they keep all the claimed Oblasts - negotiation point. UKR can not join NATO or the EU. UKR will disarm and be neutral. UKR qill allow Russian observers access to all documents/facilities described above; all non-negotiable.
Heads Russia wins; Tails Russia wins.
So, Ukraine gets to keep all the Russian territory it currently holds.
The idea Ukraine would disarm now, after fighting for survival for over two years, is absurd.
