> It would be like Biden fleeing America because Congress condemned him and some Trump supporters with a few guns camped out in DC. More of an abdication than a coup.
No national leader this weak and incompetent can reasonably expect to remain in power. When your people hate your decisions and protest, you have to do something to satisfy them, or they might become ungovernable. That's on you, not on them or on foreigners.
Unsurprisingly, large majorities of Ukrainians regard Yanukovich as the worst leader they've ever had.
The question is, does having a democratically elected national leader so weak and incompetent a stable democracy make?
An obvious answer is "no", in this sense, Ukraine have always been a failure politically. Some outside parties may benefit from Ukraine's sorry state, but that's it. I wonder if you are able to draw a different picture.
And before you ask, it seems that American democracy is in a bad condition too, but not nearly as bad yet.
It is obvious that when you have points of weakness, bad things happen to you (Russia knows it like no other), so the point of a stable democratic countries is to not have significant points of weakness.
Totally unrelated to the street violence in the capital at the time?
I'm not sure how your narrative may even stand on its own.
