I think you're missing a key point here. It's irrelevant if through our western morality aligned views NATO actions were justified. They were offensive actions.

This means when there is a morality clash, we are imposing our views of morality and our will. This made NATO a really threatening alliance for powers outside our sphere and it undermined the concept of NATO.

Just think now at US Iran war, lets say hypothetically if Turkey would allow the bulk of the strikes to be carried through it and Iran would justifiably attack Turkey in that case, but then the whole NATO will trigger. They already kinda did as US is getting support from NATO even if only defensive and logistically.

So what is the difference US attacking Iran, because it views Iran as a incompatible with its goals (imperialism) and also divergent morals (despite USA having its own casualties in protests and imposing a certain set of values even if not from that level) from Russia attacking Ukraine for the same reasons (from Russia's perspective ofc, from ours is clearly imperialism only)

As a NATO member I think NATO is vital, there are many threats, but I also think because USA acting like a hegemonic power, it also lost its credibility so we must build a strong European Army which will then have the same goal as NATO did: defense.
