nato's intention has been to encircle and trap russia. to do so they brought the baltics (estonia, latvia, lithuania) into nato in the 2004, they supported a successful coup in ukraine in 2014 and attempted a coup in belarus in 2020.
now check out russia's western border in the above. people usually arent just doing things because theyre "nutjobs." russia struck ukraine to try to bring it back from the west, and because the russian populations in the east have been in a low level civil war with the rest of the country for years now. for the security of the russian state, they do not want their western border surrounded by an enemy military alliance. russia is not actually attempting to "reform the USSR" and thats propaganda.
since at least 2014, the west has been using far right ukrainian nationalists as a proxy tool to separate the country from russian influence. now they are arming and training them directly to fight the russians. they use these people because they are a useful and enthusiastic tool against russia. the problem with that is that theyre nazis. no, im not saying nato's "directive" is to make a new hitler. i am saying working arm-in-arm with nazis is bad, and nato doesnt care because they're only focused on their goal of countering russia and these guys will fight to the death.
this is a bad tactic because #1 nazis are the worst, if youre working with nazis to fight your war then you have no moral high ground. #2 because racist nazi trash having power is going to be really bad for local minority populations (jews, immigrants, etc) and neighboring countries, and #3 blowback. like, how did pumping up the mujahideen in afghanistan go? it led to 9/11. far right nationalist extremists defending their country... turned into isis.
these nazis in ukraine are probably already now the most potent military force in the country thanks to the mutual eagerness of themselves and nato. unless russia crushes them.... theyre gonna dominate the ukrainian military and political landscape postwar. That is BAD
