Not sure about the 'good feeling' though. :-/
About NATO intervention in Ukr. The end of Russian wannabe imperialism.
At least I had an excuse in January-February 2022 to be such an idiot as you are.
This war is about Russians being butthurt about their decline and no longer being able to impose their will on neighbours. They want to be an empire again, they think they're owed a sphere of influence like China or the US. But they are just a chinese client state, them making demands and invading Ukraine, is no different than Poland demanding Belarus to break relations with Russia, and then invading it "for the safety of Poland" when they refuse. This is an action that superpower can take, not a vassal of one. Pootin in his delusion thought srus can still count as superpower, that quick decapitation strike and occupation of the entire Ukraine will bring their international credibility back, but ofc it backfired horrendously, and now they're stuck with this catastrophic, embarassing war for years, trying to salvage the situation and get out of this mess without losing power, while shills just seethe and write essays about some fantasy stuff that exists only in their heads.
