Henry Kissinger.
Wiser words have never been said.
My guess
In absence of apocalypse (aka large continental kinetic war between Europe/NATO and Russia),
what was known as Ukraine, after been dumped by US/NATO and largely destroyed and depopulated by the attrition war, will be partitioned.
At least in 2 parts (maybe more). The longer war lasts the furthest Russia will advance to the West.
In a decade or so the eastern (novorossia+odessa region?) annexed by Russia and rebuilt will fare much better than ever had under "independent" Ukraine. The smaller western rump Ukraine will be either a failed state or a defacto occupied province of Poland (Hungary and Romania will maybe slice their own piece) kept barely alive by EU taxpayers. Ukraine nationalist terrorist organization/mafia warlords will be a serious proble both West and East of Dniepr.
