The US has been involved in one proxy war after another with Russia for decades. It’s just standard US foreign policy, and it simply can’t be denied - US ISR is providing actual strike targeting information.
Regardless, it’s just more of the same. See: Vietnam, Ethiopia/Somalia, Afghanistan, and half a dozen others.
Proxy wars are just the way that wars are going to be fought between peer/near-peer powers, because a full blown confrontation risks global catastrophe.
Ukraine was just foolish enough to sign up for the role of “US’s cannon fodder” in the never ending US-Russia war.
When - not if - when, China ends up getting involved, we will likely see a shift from a unipolar world to a multipolar world and the end of US hegemony and European colonialism.
I’m sure I’ll get flagged for going against the Russia bad US good narrative though.
