Whatever it is, I still don't get the decision of such a scale operation. Russia would sink even if he'd win, so what's the point?
After switch in US politics in 2008 the new guard started going back at Russia and their geopolitical pretenses. There's a great video from American expert giving an university talk on this in 2015 after the 1st crisis. And there's a trending video on YT right now which explains possible motives for this invasion due to some new gas field discoveries.
Nothing of this is really relevant to stop what the maniac is doing now to Ukraine.
However if you want to change things you begin with yourself. Personally, or as a society. So if we have a idiot in Kremlin that's willing to produce such a humanitarian crisis on Euro soil, that's one thing, but if we have allies who are willing to let their oil companies buy out dirty politicians in the Ukraine and directly provoke Kremlin, there's something we can work on.
Tomorrow when Russians fall back and Ukraine is in talks to get into EU, the Eastern EU region might have its own new set of problems due to historical revisionism Ukraine lately did (war -> nationalism), and we might have new energy issues due to switching Russian gas to Ukrainian oligarch built via American corporate money.
Nothing has priority right now but peace and Russian forces getting out of Ukraine.
But there is always someone profiting from war on all sides. We can't call ourselves a moral beacon if we don't take care of those rotten apples first thing after the fighting stops.
For the gas issue looks like Germany is pledging to go all green until 2030s so it does slip off the relevancy chart.
Gas is one of the main ingredients in the cause-consequence, deleting that from our lives will remove leverage over Europe from Russians or any other potential bad vendor, not to mention the gratitude of mother nature.
