The claim that Soros organized Ukraine's 2004 Orange Revolution is standard Russian agit-prop, but I've seen no actual evidence proving whatever Soros contributed had any material effect on events, or that things would have gone differently without Soros.
What's certain is that Ukrainians then and today overwhelmingly want their independence from "mother Russia's" deadly embrace and are willing to take help from whomever can support them.
So Russia's claims of sovereignty over Ukraine (or anywhere else!) are unspeakably insane and Russia's numerous threats against, and invasions of, it's neighbors are pure evil, well outside the scope of acceptable human behavior.
Vlad the Invader is a genuine mass-murdering war criminal and Russians who follow illegal orders are themselves guilty too.
Those are simple facts, we ignore them at our own extreme peril.
