maybe the people of the donbas region just wanted their own territory. its called secession.
its legit process in my eyes but not in the eyes of ukraine government i guess

> explain me what it is, I still can't understand.

denazification would be if all "laws" against a small group in a country get canceled, in the ukraine example it would be the law that russian language is forbidden or east ukrainiens dont get payed pension anymore or similar things

thanks for the info about Slaviansk.
do you think a small group could capture a 100k city if the inhabitants wouldnt support the small group at all?

on the krim there was a referendum 
the problem is that west just doesnt except it.
but how else it would be possible for a region to do secession?

i also think that the whole story is more complex and thats why i dont trust west / nato mainstream propaganda news... all what they tell is putin bad, selensky good  russia bad, nato good... and that is just not the case
