The crux of your post is Maiden.
Instead of pretending to have done the research and paraphrasing someone else, I’ll link you to one of the more comprehensive articles I have found on this topic, Quora: https://www.quora.com/Did-the-CIA-foment-the-Maidan-coup-to-oust-a-pro-Russian-president-of-Ukraine (very well sourced)
It’s probably a little much for you to read. But I won’t summarize it since it’s already pretty lean (not a lot of fluff), just a lot of information.
Not included in this persons write up, is some of the testimony by Nuland where she hints that we caused this, and admitted to having the state department spend $5 billion USD on directly trying to influence the political landscape in Ukraine up until Maiden. Also not included in this write up are the much later released details about 12 CIA bases throughout Ukraine conducting operations both targeting the Ukrainian government and Russia.
Well, thank you for that. Quora won't load for me, given my "outdated browser", so I'll have to stick to the foot-high stack of dead tree books I've collected in the last year or two on Ukraine, Russia, and postwar Europe.
I'll forgive you that bit of snark since you don't know that I am nearly 80 and mobility handicapped just short of a wheelchair. All I do is read, eat, sleep and excrete, not to put too fine a point on it. This frustrating near-immobility is why I waste so much time arguing with Russophiles on FR.

Curiously, your link provides not a single piece of data supporting allegations of a 2014 Ukrainian "coup" -- whether "engineered" by the CIA or anybody else -- or of logic explaining how this mythical "coup" somehow justified Vlad the Invader's invasion of Ukraine & annexation of Crimea and the Donbas.
The fact is Russia's "coup" narrative is false in every aspect, and anyone who takes it seriously has to be doing so from motives which defy comprehension by normal patriotic Americans, or anyone else.
