Russia’s moral dilemma which must be addressed

Russia’s moral dilemma which must be addressed.

How do you fight an enemy which is literally insane and which requires the destruction of its troops which  for all intents and purposes are, to be quite honest, innocent pawns  and the future of Ukraine?
Is there another way?
Wouldn’t it rather be more beneficial to overthrow the government in Kiev?
Is Russia really that afraid to be seen as following in the footsteps of the USA but without the protection of the Western media afforded to their “colour” revolutions and those predating the colour motif?
Is it simply perception that Russia fears?
Or is it complicated?
To answer this question we have to determine as far as we can discern, what the West’s reaction to such a move would entail.
The obvious is a propaganda avalanche on a Russian pitch for world domination with Ukraine being only the first domino, as was the North Vietnamese communist domino theory used by Australia to justify its all the way with LBJ crap in the 60’s.
Make no mistake the west will put whatever evil spin it can come up with to demonise the overthrow of Zelensky.
This can be mitigated however by replacing his government such as it is with a Ukrainian and not Russian power structure, ideally from the military and ideally seen to be supported, which it would be in any case by the Ukrainian population, especially if it restores peace and enables the return of the millions displaced by the war.
It seems like a simple solution but what roadblocks would the West put in the way apart from a thus doomed to fail propaganda blitz?
They can’t do any more economically, financially, diplomatically and politically.
Their only redress would be military and is this what Russia is trying to avoid…WWIII?
Maybe Russia knows something we don’t.
Maybe they know the West is itching for a reason to start one.
Maybe that reason is a false and hypothetical Vietnam war style domino theory.
The reality is just the opposite.
But the West does not deal in reality. It is not governed by reality, is not beholden to reality.
The figurehead of which, with his finger on the button is Joe Biden.
Suddenly Joe Stalin looks sane by comparison. Oh!…..No!
