Ukraine has nothing to win and everything to lose...
they are being mugged by a brute force bully, and the best they can hope to reach is survival. survival at a horrible cost in loss of life and incredible material costs.
history teaches that even if Russia is defeated on the Ukrainian battle field reparations wont help much in restoring civic relations with their eastern neighbors
what I expect to happen now is a consistent rain of drone, cruise missiles, shelling and rocket artillery attacks at random civil locations to grind wear public moral into pulp over winter (which is pretty cold in Ukraine in a typical winter, especially when electricity infrastructure is down, and all window panes are shattered.)
at the same time russia will reinforce their material and personnel as well as they can. and build up the annexed provinces, preferably with a lot of soft targets. Every time Ukraine will fire into these targets, the russian media will screech how the evil Ukrainians are killing off innocent and unarmed people, and will forget to mention those people were put there as cannon fodder in the first place. The Kremline has an interest in an angry population that sees Ukrainians as evil people, and hates the west as a corrupt and perverted system.
They will pull Belarus deeper into their fold, with more an permanent military installations to improve their reach into Ukraine. At the same time they will suppress potential belarussian uprisings (which are simmering unrneath the surface). Lukachenko already seems to bend over, and the Putin needs to show some gain from all his efforts to minimize loss of face...
We can expect further economic warfare into Europe through energy scarcity and a further amplification of the political extremes through their troll farms to destabilize opposing forces like the US.
Russia at this moment has an interest in a destabilized west, with high inflations in the UK, Mainland Europe and the US.
and then... spring next year the misery continues.... there is no winning in this kind of conflict.
