I hate all these power hungry psychos like Victoria Neuland and Putin who helped manufacture this civil war just so that they could get a little cut of the bounty. How people still believe capitalists states work in their interest is beyond me. Hunter Biden was earning 100x what the average Ukrainian earned in consulting fees in Ukraine. The whole point of the Ukrainian state since the collapse of the the USSR has been to shovel money from the state into the hands of which ever elite currently controlled the country it’s irrelevant whether they were backed by the west or Russia.
Kinda answered your own question there. Idealism only takes most people so far.
Anarchists are a very tiny minority everywhere. It does not make sense to judge the entire country by them.
"If all Ukrainians wanted to fight in this war"
They don't, but neither do all Russians. Moscow is trying really hard to avoid general mobilization.
Frankly I think the actually association is probably shallower than anonymous internet self-proclaimed leftists would have you think, but it's still impressive how powerful it appears.
