This is just elevated whataboutism

I'm not sure how correcting the term that you repeatedly used is "whataboutism". Surely you meant something when you wrote "sovereign country" multiple times? It's just inaccurate, it would be like referring to the US as a kingdom or referring to Washington D.C. as a country.

Why doesn't Putin just say that? Why would he insist on mislabelling this as an "SMO" instead of a war of liberation?

Modern countries don't like to call their wars a war for some reason. The "Special Military Operation" labeling in particular is based Ukraine labeling their war against the Donbas Republics as an "Anti-Terrorist Operation". Russia did state that one of their goals was the liberation of the Donbas Republics.

And why wouldn't Russia use the same means to subvert their subversion instead of resorting to bombing civilians?

Russia is far worse at subverting countries than the US is. The US has massive experience in fomenting color revolutions in foreign countries, using NGOs to undermine foreign governments, and in supporting far-right movements within countries and using them to topple or put pressure on those hostile (to the US) governments. Russia did attempt to use diplomacy (for eight years) to stop Ukraine's bombing of civilians in Donbas but that didn't work out. Russia tried one last resort by diplomatically recognizing the Donbas Republics but that just caused Ukraine to start shelling the Donbas even harder.

Don't tell me....the verified evidence of countless war crimes are just propaganda right? For which you're going to offer no counter evidence.

All war is a crime and all wars come with war crimes. Some war crimes were committed by Russia, some were committed by Ukraine and then blamed on Russia, and some were pure atrocity propaganda that was just made up. The made up atrocity propaganda was so bad that the Ukrainian Rada (parliament) had to fire their commissioner for human rights. She was just spreading made-up atrocity propaganda and also wasn't bothering to organize the evacuation of civilians.

As for the accuracy of your accusation - do you have some sources? I'm interested to read and learn about your viewpoint. Assuming that it's not just your armchair intelligence briefing.

Here's an overview. Click the links to get details about the parts you're interested in.

The short version is that the National Endowment for Democracy (a CIA cut-out) has openly spent over $5 Billion dollars to "promote democracy" in Ukraine. Do you remember how much the US freaked out over Prigozhin (Wagner guy) spending a hundred thousand dollars in order to "promote democracy" in the US? John McCain and Victoria Nuland openly met with the protestors and announced their full support and the backing of the US. Nuland had a leaked phone call where she was hand-selecting the new leader of Ukraine. The new Ukrainian Finance Minister become a Ukrainian citizen the very same day she was sworn in as Finance Minister.

As a bonus. Here's one of the guys that McCain met with.

Tyahnybok himself was expelled from the Our Ukraine parliamentary faction in 2004 after giving a speech demanding that Ukrainians fight against a "Muscovite-Jewish mafia" (he later clarified this by saying that he actually had Jewish friends and was only against to "a group of Jewish oligarchs who control Ukraine and against Jewish-Bolsheviks [in the past]"). In 2005 he wrote open letters demanding Ukraine do more to halt "criminal activities" of "organized Jewry," and, even now, Svoboda openly calls for Ukrainian citizens to have their ethnicity printed onto their passports.

Tyahnybok is a prominent leader in the Ukrainian protests, so perhaps it was only right that McCain met with him as he did with the others (we reached out to McCain's office to find out how much he interacted with Tyahnybok, but have not heard back at the time of writing). You can defintely understand, however, why Jewish leaders in Ukraine and abroad are concerned about him.
