no it's not the "whole globe's problem" - it's not even a NATO state we went to war with Russia over.Libya, Iraq, Syria - these are all apples to watermelons comparisons.
This is the entire globe's problem. Honestly, it's useless for us to really try to "debate" the Ukraine conflict. I'm mystified by your position and attempts to take blame off of Putin. This is entirely his war, and his actions have made it our problem - not just Europe's. That really sounds like Chamberlain kind of stuff.
It's essence is still a border war between Russia and Ukraine
If you had said "China is the whole globe's problem" you would have a had a clue
But you listen to Biden and Zelnsky trying to sell this war as an existential threat

The only existential threat is if we make it one by warring against Russia
Meanwhile China uses it's soft power (know what that is?) to suck up African resources and
replace Pax Americana with the CCP fascists
