Every claim you made, beginning with calling the Maidan Revolution a "coup". Almost one million people protesting in the streets in the Maidan, in response to a corrupt Russian puppet beating people in the streets and stripping them naked in the snow on TV, is not a "coup", no matter how badly you want to believe it is.
And since that so-called "coup," Ukraine has never once turned its back on that revolution in subsequent elections.
Meanwhile, what does Russia have to show for all its bullshit? Not even the Eastern regions, from whence Zelenskyy himself hails--a native Russian speaker-- such as Kharkiv, bent the knee to Russia, even as Moscow shelled Kharkiv city and its surrounding villages killing "Russians" Putin claimed he was liberating.
There was violence both ways, so I don’t see any moral superiority one way or the other. And one million protesting in the streets, even if accurate, means 50+ million were not. At any rate that’s not how government is legitimately changed. Mob rule was detested by the American founders for good reason.
