A couple of years of ukranians shelling the prorussian regions were a good enough reason.... considering that nato used the same one to bomb serbia in 1999.
2021 only had 18 civilian deaths in that region, of which 11 were caused by mines. 79% of casualties were in separatist areas and 21% in Ukrainian controlled territory. That is a good enough reason to kill thousands and thousand, make millions of Ukrainian children flee their homes? Level entire cities?
Any evidence for genocides of pro-Russian populations in Donbas similar to Serbia's of Albanians?
What genocide? It was a fight against KLA, a group even americans marked as terrorists.
