The situation with Palestine and Israel is shit and has been shit for a long time now. Hamas are a bunch of bastards that are standing up against another bunch of bastards. They both suck and neither Hamas nor Israel should be shown any support at all. It's like when the USSR fought the Nazis in WW2, neither option there was good, and just because the Nazis were slightly worse doesn't mean the USSR deserved support.
That said while Hamas absolutely doesn't deserve any support, Palestine and the Palestinian people absolutely do, and the way they've been treated by Israel even before the current situation is terrible. The current situation is so much worse though, with Israel just going full mask off genocide now.
Even if the US isn't going to get involved in that conflict directly the least we could have done is just not support Israel, don't provide them with weapons, shut the fuck up when other countries start accusing them of war crimes and genocide. Instead we're doing the exact opposite, sending weapons to Israel and using our international clout to shield them.
