The conflict cannot be resolved, because, essentially, it is not really a conflict. It is one nation, possibly even just one man's, crusade against another country. The only thing that can stop the apparent momentum to an all-out war is a judgment by that person that he risks too much by carrying on. All the stuff about NATO is merely a smokescreen, although it is a fact that these territorial issues created and aggravated by Russia would, under current NATO rules, disbar Ukraine from joining anyway.
What happened yesterday has been building since last Friday when the so-called breakaway republics issued statements (recorded two days previously) calling on its citizens to evacuate. Since then there's been an almost farcical inevitability about the train of events.
I'm pretty sure that in his hysterical monologue Putin talked about redrawing the boundaries of those republics: currently they only include the actual cities and some surrounding areas, not the whole oblasts. So presumably the next move would be to annexe Donetsk and Luhansk oblasts in their entirety. Possibly to this end, Russia declared a no-fly zone over the Sea of Azov, which is the inlet of the Black Sea in the far SE of Ukraine. They have cruise missile launchers stationed there and amphibious landers.
Tony's link about press gangs is interesting and hardly surprising.
In fact for years, anyone under the age of 30 has largely been prevented from leaving these enclaves. No one sane would wish to stay there if they had a chance to leave.
