Your misspelling of Ukraine's capital betrays your bias.
You ignore a simple asymmetrical fact: if the land-based colonial empire called Russia stops fighting, the war ends.
If Ukraine stops fighting, it ceases to exist.
A negotiated truce that leaves Russian military power intact merely gives this genocidal empire time to prepare round two. Therefore the only viable endgame must leave Russian interest in and capacity for empire the same as that of Germany, Japan and Italy in 1945: zero.
The final outcome must be to separate Russian national identity from empire by freeingtheempire's subjugated peoples. If you don't understand this, you understand nothing about Russian history or the nature of the Russian state Peter and Catherine built.
Russian empire, Russia's identification of nationhood with empire and Ukrainian independence are irreconcilable opposites. Only one will survive this war. Choose which you prefer.
