Personally, I think the Ukrainian war is a disaster for both Russia and Ukraine. Ukraine will be a wasteland and Russia's international standing will be damaged for decades - unless they can get rid of Poot. Think of all the parents on both sides finding out that their only son is dead. I travelled across Russia about 5 years ago, and found Russians to be decent enough people.
I think your use of the Azov battalion as an excuse to brand Ukrainians as neo-nazis is very weak. A motorized battalion is likely to consist of no more than 1500 people, and probably less than 1000 - a fraction of Ukrainian forces. One could justifiably use the presence of Wagner Group personnel and Chechens to call the Russians Nazis. Militarily they are very effective, not unlike the SS in WW2: highly politically motivated forces are like that.
Personally, I would love to see a future in which Russia and "the west" cooperate to meet the many challenges facing the world, not least climate change, but I expect that will be off the table for a few years - right when it matters.
I also wonder if there are major global powers waiting quietly in the wings for the Russians to dash their state on the rocks of the Ukrainian war, so they can get unrestricted access to all those lovely resources..
