Certainly not "support", no. But frankly, the US has repeatedly been the ones to arm the fascists. That the US is getting involved in this particular fight has probably more to do with their opposition to Russian influence than any stand for justice or protection of the innocent. To say there isn't much trust in the US acting in anyone's interest except their own would be a monumental understatement.

I would say (everything beyond this point is my own speculation, since they aren't here to answer your question), they would rather a treaty be struck sooner rather than later, which would mean the US easing up on lethal aid. I think their general position is that not Russia, Ukraine, nor the US have the interests of the actual working class (or women or LGTBQ+ people) in mind, and the sooner the war ends the fewer people die and the sooner the real work of fighting for those rights can begin. But there will be nothing good about the reconstruction that happens after the war. Ukraine will be beholden to US interests and perpetually in the middle of a geopolitical conflict with Russia for the foreseeable future (no matter what the resolution of the war is). The whole situation is shit, but "let them fight until the bitter end" is probably the least empathetic take I could think of.

I really hate that anything less than "Russia will loose at all costs" will get you lambasted with accusations of simping for Russia. There are precious few here who are willing to acknowledge that there are no good options with this war. I guess it's easier to let the anger drive decisions when there are no satisfactory solutions to the conflict.
