The problem with your argument against Israel is that everyone around them is so much worse. None of the countries around them respect any form of human rights, and some of them (including Hamas) actively want to try and commit their own genocides. This much was obvious given how Hamas fighters acted on the Oct attacks (I think it should be common knowledge that they did target civilians as apposed to just military targets, however here is a taste [https://www.youtube.com/watch?v=Ch6T9oR6tro]).
"The only thing US brings to the world is horror and suffering.", this should be an obviously hyperbolic statement. What about World War II? Are you not saying that the U.S. at least brought some good by fighting the Nazi's.
"It’s pretty obvious what genocide Joe should do. He should pack up and leave". First of all, it is abhorrent to say anyone should do any sort of genocide. I know you likely didn't mean it like that, and I don't want you to think I'm trying to nit pick. I just want to encourage people to be careful with their words.
My second point on that quote, is that your missing the point. Have a little empathy. Regardless of how effective it would be at curbing Israelis actions in Gaza, this would have severe ramifications on civilians. Despite our shared thoughts on Israel, withdrawing US troops would likely both do nothing to curb Israels attacks on Gaza (Israel has a long history of operating fine without the US [2]) and it would only put Israeli lives at risk due to the bombing campaigns conducted by groups like Hamas.

"Everyone around them is a direct product of US meddling sine time immemorial", I think I can agree to this statement. However just because you shouldn't have gone in, does not mean you should leave.
Look at how the us withdraw from Iraq. It may even have been a good Idea to withdraw, however it was not a good Idea to make a hasty retreat like the US did.
Its same with Israel. If removing our selves actually don't do anything to Israel, than we are just putting more Israeli lives at risk. Removing our supply of munitions would likely force Israel to pivot to primarily using ground forces which we would be an even worse outcome [1].
If withdrawing ourselves from Israel did have an effect on them, it would leave Israel on the Blackfoot and could risk the lives of innocent Israelis.
"And yes, have a little sympathy for the millions...". I agree, it is sad that innocent people are dying. The sad truth is we're in a catch 22 between the Islamic extremists and a country that make questionable moral choices. The problem is that their isn't anything the US could do that would really effect the situation.
Biden is taking some action, pressuring Netanyahu to actually come up with a plan for Gaza that will end the endless loop of war in the area [2].
He also has started posturing towards Israel that things should be ramped down [3]. Athough it may not be the feel good story everyone wants from our democrat president, it is a pragmatic one. Focused on considering the lives of Palestinians and Israelis alike.
