I don't think you understand the history of the area nor what has taken place. Which is understandable if the lens is Western media.
The British were after Crimea 180 years ago. (see charge of the light brigade) It's a big prize. And it had been Russian from the 1700s until 1956. And now it is again. Likewise many of the breakaway republics (until 1920s). And what happened to Russia in the 90s. How the borders of Ukraine came to be. What happened in Kosovo. How American "imperialism" works, and what it is.
That is not to excuse any Russian behavior either. They have traditionally been imperialistic and expansionist. Their neighbors have reasonable cause to fear them.
But this is multiple parties instigating civil war, inserting puppet governments, creating propaganda, stirring up hate and taking sides, arming and providing intelligence for their own gain.
It's not at all just "Evil Russia and we are helping democracy!" in reality. This sentiment, (targeted at the historical and event illiterate) is propaganda to get you to play along, pay for it, fight for it or at least not complain. And the same holds true with whatever Russian media is telling it's citizens. I'm sure it has a very good story about evil imperialists and the misdeeds of the CIA, so that's why the rich should get richer and you should put on army fatigues.
It's an economic war. Like most, or even all wars are in reality.
War is a racket. Always has been. The little people pay with blood, the big people stand to turn big profits and maybe if they are lucky the little people enjoy a favored economic position later at the expense of whomever they subjugated.
It's frankly shocking to me that people don't understand this by now.
