NATO is purely a defensive pact, nowhere in it's charter is there any provision for initiating hostilities and there is zero political support in the west for aggression against Russia or the acquisition of Russian territory. Until February the west was absolutely more than happy to funnel billions into Russia in return for oil and gas, and almost pathologically avoided any thought of taking any action that might affect trade with Russia.
There's one problem with that statement above when I said this:
>zero political support in the west for aggression against Russia or the acquisition of Russian territory
The problem is the west and Russia have very different ideas about what constitutes Russian territory. Putin has been crystal clear, in numerous speeches and written statements, that he considers several other countries 'Russian territory' including Belarus, Georgia, the 'stans' and Ukraine.
Ukraine joining the EU or NATO would forever take it out of the political and economic domination of Russia, and that's what he can't tolerate. In his mind that's a hostile takeover of territory that rightfully belongs to Russia and that's why he went to war. It's why in his opinion he had to go to war. He's not actually lying when he tells Russians that the west forced his hand and this is about the defence of Russia, because in his mind Ukraine is Russian territory in the same way that China considers Taiwan Chinese territory. When he says Russia, he doesn't mean the same thing that NATO leaders say when they use the same word.
So those who say they agree with Putin or agree that NATO forced his hand, are signing up to the same view of the status of Ukraine and therefore the Ukrainian people.
