Or... maybe you are getting paid for saying so, blurting the official buzzwords over and over to see what part of the shit sticks and somehow feeling that you are doing yourself a favour.
The answer is much simpler: people do not like being shot at, being threatened with nuclear weapons and getting their countries invaded. If you do that, you will get people saying that you should not do any of that and that they are willing to fight back for mere self preservation. If in doubt go to any six year old and ask him how he likes the school bully.
Well, of course. There wasn't only one reason why Russia did its police action. But the reasons you mentioned were sure part of it. Russia wanted to stop the Ukraine and the US and Nato from all that stuff. But the US is stubborn. And Ukraine is stupid.
So, what do we have, now? A bunch of Nato countries that are falling apart, and plowed ground in Ukraine... plowed for spring planting. And, millions of Ukraine citizens leaving Ukraine because they didn't want the war that Zelensky and other leaders were promoting.
Tease the bear, and you will get clawed to pieces, chewed up and spit out.
