Even if China doesn't explicitly align with Russia, I believe there are strategic reasons why the US would want a favourable outcome for Ukraine. I outlined a few points in a post a couple of weeks ago: https://news.ycombinator.com/item?id=42059787
I'm no international relations hawk though, so I'm keen to hear opposing viewpoints.
I used to support Ukraine winning the war at any cost (them losing and that result being recognized implies that warmongering is acceptable). However, that war is now in its third year with no end in sight.
Our (the west's) response to warmongering has been to trickle just enough resources and monies to keep Ukraine from losing but not so much that they win. The "donated" resources of course need to be replenished, the military industrial complex is quite literally making a killing.
At this point the question of declaring a firm stand against warmongering is lost. It's three years and going, warmongering as it turns out is fine. I hate that. My tax dollars are going towards endlessly and needlessly extending human suffering for the benefit of the military industrial complex. I hate that.
So I say, enough of this bullshit. Unless we suddenly send in so much support that Ukraine decisively wins very quickly, I don't want to see a single cent more of my tax dollars going towards this. My taxes are not blood money and the military industrial complex can go fuck themselves.
I agree with what you have said here, but I don't know if the US is in a position to turn the war around in 2024 without a huge escalation. It remains to be seen if there is any possible way to do that without "boots on the ground" (formally starting WW III) or the use of nuclear weapons (again, formally starting WW III).
There were plenty of options to pressure Ukraine into preventing Russia from having a causus belli in early 2022 (too bad the Biden admin didn't do any of those), but those are gone now and Russia currently controls much of the territory they had as military objectives.
