I think many people in the U.S. do feel extremely shitty about it. People do care, people are upset, and many are protesting and talking and doing what they can to try to mitigate or heal or push back against the actions of their own governments in the ways that they can. I don’t know if you were around for the 2000s, but people protested then, too. It may not feel that way depending on what media you see or what people you know, but many people do strongly criticize their own government and feel awful about the way their tax dollars are used and the rhetoric that comes out of their leaders. I think most americans (offline anyway) do condemn war crimes, do feel icky about our own government’s involvement and motives, and are mourning the suffering on both sides of this conflict. If you’re seeing lots of disregard for human life around you, it might help to seek out some of the groups and voices and people who are feeling unsettled and are doing something. I know there are lots of donations happening and I’ve seen news about events mourning the dead and groups trying to help the people who are there. It might not be on every front page, but it is out there, if you look for it. The people loudly saying that death and suffering is justified for certain groups of people will try to make it seem like everybody feels that way. But in practice, that has never been true. Anyone with a heart hates this shit. So many people are trying to help. Don’t let propagandists convince you otherwise.
