Maybe Americans shouldn't care about supporting Ukraine. I think the bigger factor is that enough Americans don't like Russia, and therefore aren't picky about who to help fight Russia, and they likewise probably don't care about Gonzalo either. But his death will be used to turn away some support from Ukraine. It seems like the aid to Ukraine will dry up during 2024/2025 at any rate.
I think the hatred for Russia is all contingent on the propaganda that is put out by the
people who actually want Russia to be balkanized. Government/NGO people

The thing is normies don't pay attention. Normies don't read reports. They don't see that. That's why everyone uses stupid superhero metaphors.
This isn't a new phenomenon, what is a new phenomenon is the items being used to promote the war effort are largely despised these days because of how bad they are.
When Chaplin made "The Great Dictator" he was one of the most well liked comedic figures in the country. The movie was well made, and the speech he makes at the end speaks to the American way of the time.
Nowadays people are tired of Star Wars, Capeshit, famous people singing songs about coming together, and dancing tik tok nurses. it just doesn't work because the people are demoralized at home.
Boomers may have some kind of nostalgia for the USSR being the big evil, so that gets played up but at the same time Russia's allyship with arab causes clashes with that in regards to how a lot of leftists are "Free palestine" people.
Russia's posture on religion and being "anti-woke" clashes with the gay stuff that the right wing in america is tired of.
"RUSSIA INVADES UKRAINE, WE MUST HELP PROTECT THEM" as a "PROTECT US INTERESTS" really only works if people don't remember that the US spent 15 or so years messing around in Iraq and Afghanistan only to lose Afghanistan, and have the Iranians become stronger while giving the Russians opportunity to grow stronger by fighting ISIS and protecting Assad which strengthened those ties.
That is to say, support for Ukraine only works when its "the current thing", and because there are so many current things, it falls by the wayside leaving only people who have been paying attention for more than a few minutes to think about it. No doubt Gonzalo's story will not be the current thing either. But the people who are part of the counter-narrative archive these stories for later.
When the topic comes up again, the normies get to see the mountains of contradictions that exist within the discourse. This is just another one of those headlines that gets thrown on top of the pile.
I would say Ukraine better hurry up, because if Trump gets elected again, and the Republicans take over they're in trouble because he's never gonna give them money. They already can't get a bill passed in front of Mike Johnson.
Ukraine planned poorly, and this is another one of those things that makes them look bad.
When they hit a bridge, take out a plane, or ships in dry dock its a propaganda victory. When they tie people up to fence posts, throw them in cars for conscription, shoot prisoners its a bad look.
And this is the side that didn't have one of their PMC leaders rebel against the siloviki in charge, lol.
