you sadly seem to still be chewing american propaganda. russia was demanding that the ukraine would return to the status of of neutrality that it had before the 2014 cia-backed neonazi coup. the demilitarization is necessary, just like the denazification in order to guarantee an absence of any further military threat to the russian population within the country, a population that the current fascist ukrainian government previously tried to mass murder. also belarus is clearly not a puppet state of anybody, despite nato propaganda painting it as such. just look at their economic relations.
also, russia is currently a vital part in the worldwide anti imperialist axis of resistance, and while i would argue that the government should be doing more to help the palestinians, it is still much better than any western nation.
