i'm sure you are correct. and the leash that Ukraine has been on has been calculated to make this last as long as necessary to bring the Russian economy to its knees...
but taking a side is easy... Ukraine, with all of its resources as part of the western economies? or bigger yachts for oligarchs? fuck the Russian ruling class! if they lose this the whole thing may implode and Russia will join NATO as well! next!
Fuck anyone's ruling class, to be honest. The rich are the rich, and wherever you go, they have more in common with the rich from other nations than they do with the lower-downs of their own people.
As for Russia joining NATO, when the Cold War was over, some in the 1990's had proposed that Russia could join it, imagining a single military alliance all the way across the north of the world.
It never happened, or course, because one thing about NATO is that Washington exercises too much control for it to allow someone like Russia in, and Russia would not want to accept that level of control. (Multi-polar world order was okay, not unipolar.)
Russia (and Putin's actions do indicate this), I think then switched to the hope that they could become stronger allies with the European powers, like Germany, that were in their own way keen to create a military alliance for the EU which did not involve the Americans.
Even if Russia's regime and the EU never entered into any formal agreement, if the EU could learn to push the US out of their own decision making, and/or counternalance their need for military strength (and energy resources) by turnbing to Russia, Russia cpuld then boost its own stature and economy, and both of them could better guard against threats from their southern frontier (a.k.a. aggressive Islamic powers).
Picture something like an alliance of European nations, minus the US and maybe minus Turkey too, but plus Russia. Result? Peace across the north of Eurasia, all the way from Iceland to eastern Siberia.
What power would that sort of alliance deprive of influence, military presence, and wealth? Well, primarily, the USA.
And now you can see why the US would rather have a war in Europe to justify NATO's continued existence, than ever see Russia and Europe firmly on the same side. Did US leaders consciously push events towards conflict? Well, given all the evidence, it is hard to believe Washington blundered into an unnecessary war with completely innocent intentions that were just misunderstood.
Long ago, a British commenter made the observation that NATO's purpose was to "keep the Americans in, the Russians out, and the Germans down", and it would seem that the Cold War being over did not change that one bit.
