i'm sure you already know people directly affected by this war, but if you don't and need a good "I know someone with family in Ukraine and they think ____" (because lived experience is a wedge you can use in conversations with liberals, at least sometimes) -- feel free to tell them that your friend worker_bear (make up a cool name) has family fighting on the frontlines, and appreciates when Americans don't blindly buy into narratives that call for ever-escalating bloodshed, since it ain't their cousins and nephews who are going to die in the firefights.
if they ask "well what does worker_bear suggest we do about it," I wrote a very rushed piece about a year ago when the war broke out (wrote over 2-3 sleepless days/nights, admittedly it could use some editing), but you can send them this: https://medium.com/@pyotrbarannikov/what-is-happening-in-ukraine-and-what-can-we-do-about-it-cbc6902d6c50
