China may make a bid to broker a peace (undoubtedly with Russia getting to hang onto occupied territories and Putin still in power) but why should Ukraine or NATO bite? Continuance of the war (on a primarily defensive basis) would likely lead to removal of Russia from occupied territories, Putin's removal, strengthening of Ukraine/NATO, and China/Iran/Russia/N Korea looking like the wanton colonizers/aggressors/rights suppressors they really are. That said, I wonder how long Ukraine can last, especially if/when China starts supplying arms. It could be that in a year or so, a brokered peace with Russia keeping Crimea, a reigned in Putin (admission of war crimes, pays reparations, if not outright deposed) may be in order. This may happen only if Russia's military back is broken, which raises the question "why give up even the Crimea"?
