Ok, I will not be defending those actions of NATO
You’ll just ignore their relevance to why NATO approaching your doorstep is, in fact, hostile and aggressive.
NATO was literally created to oppose the USSR and the left in Europe generally, and did not disband after the fall of the USSR, instead taking up further aggression and at greater range, and keeping a very clear encirclement position around Russia. The bases got larger, the spending increased, and membership was sought to undermine any countries stepping out of line of the American-imposed order.
The ethnic cleansing was and is part of official Ukrainian policy. Do you think the sneaky Rooskies infiltrated and forced Kyiv to drop Russian as an official language, one that could be learned and used in schools in Donbas? Did they cleverly rename the streets to Bandyerite fascist names? Did they create the Azov Batallikn, Righy Sector, etc - the Ukrainian fascist groups weaponized against the ethnic Russian civilians of Donbas and now directly incorporated into the government and armed forces? Did Russia secretly create the entire Kyiv side of the civil war that heavily targeted civilians and civilian infrastructure on the Donbas side?
Cool to learn, I didn’t know that.
