this is the problem with you shills- you are locked into a prison of binary thinking. to be clear, my support of Russia's special military operation is not uncritical, and I believe Russia's government is corrupt, dishonest and self-serving. that doesn't mean their use of pre-emptive self defense in the Ukraine was not justified.
Why do you think there was such a large concentration of Ukrainian armed forces in the Donbass? Persuasive evidence exists that the UAF was about to launch a major operation into the Donbass. the democratically-elected governments of the Donbass requested Russian assistance, which was provided.
additionally, the placement of long-range missiles in Ukraine has been a red line since at least 2014, agreed to by all parties, and arguably as far back as 2003. NATO has been deliberately provoking Russia by violating every one of their agreements.
What this really comes down to is a dispute over control of the global geopolitical narrative. NATO and the US have constituted a global hegemony exercising control over a unipolar system, which gives them the prerogative to write history as it happens- controlling the dominant narrative and by extension the parameters of reality.
The bloc led by Russia and China, but which includes over half the world's population, is currently challenging that narrative- which also includes important factors such as the global reserve currency and global security architecture. This is what Ukraine is about- not the number of APCs blown up or soldiers dead (which, as you know even if you won't/can't admit it, Ukraine has lost many more than Russia in the last 2 months)
