im convinced that you dont have good sources for news...
And I'm convinced that you'll avoid the meat of the whole thing at any cost in your quest to demonize Putin.
The Ukrainians tossed this opportunity right in his lap. They know him. They understand him better than we do. They know he's a ruthless & devious SOB who will pursue what he sees as Russia's interests any way he can. But they did it anyway, part of the rationale being the sunshine that the West has been pumping up their skirts all along.
If the Ukrainian govt can't get their shit together, they'll end up with half the country they have now, in no small part because many residents of eastern Ukraine see Mother Russia as a better alternative, just like the residents of Crimea.
When your govt, your police, your military somehow can't maintain civil society, when they depend on thuggish fascist militias to maintain what little of it there is, it's not hard to be convinced that your old govt is better, particularly when they'll take you back enthusiastically.
What sort of appeal does the ethnic ultra-nationalist rhetoric coming out of western Ukraine have for Russian speakers in east Ukraine? What's in it for them? Can they identify with it at all, or does it scare the shit out of them?
Did they ever really think of themselves as Ukrainians, or as Russians?
Demonizing Putin just hinders us from looking deeper, from looking at that, ourselves & our own govt's purposes. Does our govt care about the people caught in the middle of this episode, or do we just care about putting a NATO ally & EU member on Russia's southern border?
If our Govt actually gave a damn about the Ukrainians, any of them, we'd have done things differently. We only care about that when our Team is losing, not when we're gambling with their welfare, helping them set themselves up to fail.
Prior to independence, Ukraine had basically been part of the Russian Empire & the Soviet Union for ~200 years, 10x as long as they've been independent. And, of course, nobody asked the people in various parts of that ethnically diverse administrative area what they wanted- "You're all Ukrainians now!" covered the subject entirely. It worked well enough, apparently, at least prior to the rise of right wing ultra nationalist militias in the western part- you know, groups characterized in the western press as "protesters".
