I can understand this POV, but from my standpoint as an American, if America wins this proxy war with Russia, it's another victory for creeping totalitarianism here. It means their domestic propaganda campaign is validated. It means subverting global economic institutions and turning them into instruments of war worked. It means their ability to flip a switch and direct a huge portion of Americans to mindlessly hate an entire ethnic group passed the test. It means that the US political class can set up a puppet state as a bribe-soliciting apparatus, flaunt it, and see no real consequences at home or abroad. It means that Washington has the power to force the entire first world to be accessories to the money laundering schemes of our most corrupt families.
I'm not "for" or "against" Putin. I simply don't live in Russia or Ukraine, and winning this war will make things worse for us Americans.
