there is no "enormous nazi problem in ukraine", that is literally russian propaganda. there is much larger nazi problem in russia in fact, from existence of radical far-right groups all the way up to concentration camps for gays in Chechnya. i suggest you re-evaluate your sources.

russian invasion can't be called anything other than fascist - military glorious leader annexing a chunk of neighbour's territory under justification that people there are compatriots that need saving. you can't make that shit up.
