There is a thing called "just war". Ukraine has clearly been wronged by being attacked unprovoked. It is only right to support them. There have been instances when the West had been wrong for waging war or supporting another, except this one is different. Telling Ukraine to give up is like telling UK and Republic of China to give up as well, when Nazi Germany and Imperial Japan were rampaging amd killing civilians wantonly. And mind you, there were uninformed peaceniks and isolationists back then doing the same as you're doing now before the US entry into World War II. The naive and misinformed peaceniks and centrists somehow think they will not be affected in an increasingly globalised world. But then again, most people have tunnel vision.
Telling Ukraine to surrender is letting the UN Charter to respect national sovereignty be demolished, a cornerstone that kept world peace, for the most part, intact for the last 80 years. This enlightened centrism is only serving at the benefit of authoritarian countries that don't respect basic human decency and rules. "Evil prevails when good men do nothing", literally what this misinformed (or perhaps fake) centrist take on Russian invasion.
As for Palestine, Biden himself is getting fed up with Israel. But political pressure keeps him from abstaining support.
I'm not saying all in all that the West and US is the best option for world order-- I prefer a multipolar world-- but that's how it is right now. The West isn't some moustache twirling villain concocting plans all the time in a backroom, but there is no unified policy in the West and their policies must be judged on their own merit. Invasion of Iraq: bad. Supporting Ukraine: good. The usurping of US-led Western hegemony, which is deeply flawed, is for another time.
Also, I'm not American so I don't vote. The thing is with Americans and lack of progressives in Democratic party is that ordinary progressives do not vote, or at least mobilise. As much as establishment machinery is hard to destroy, apathy is as much to blame (which serves the corrupt both local and abroad).
