1. the US sees Israel as the only thing it can control in the middle east. it was always meant to be one of a few "pro-democracy beachheads" in the area, with the US attempting to make iraq work the same way in the 2000s. The idea was to put Israel in a position where they were powerful compared to their enemies but dependent on foreign aid, so that they could do whatever they want as long as they also did whatever we want. This is straight out of the British post-colonial hegemonic playbook - you don't send people to take over, and instead you elevate one local group from second or third place to the top and then make sure they never develop enough power that they can remain on top without your help. If you do this successfully, you can control them completely because all you have to do to send them tumbling from power is nothing when they're counting on your support.

2. Up until now, the impact of helping Israel didn't have to be all that massive because the impact of Israeli violence against Palestinians (edit: ON THE OPINION OF THE AVERAGE AMERICAN) wasn't either. What you're seeing is a replay of the US allowing anyone with a camera to report from Vietnam - the narrative used to be pretty tightly controlled but between Palestinian social media updates and Israel's internal jingoistic propaganda being leaked to the western world it's becoming harder and harder to sustain the whole 'most moral army in the world engaged in a limited defensive operation that respects the right of all law-abiding people to live in peace' narrative. We see them shooting at people gathered around aid trucks now. We hear them talking about "children of light vs children of darkness", "every Palestinian is a terrorist because they all support Hamas" and seizing all of Palestine to build beachfront condos. Americans tend to like war in theory, but we have a strong sense of fair play and we'll only stay on board up to a certain amount of video of unarmed people being mowed down by soldiers. This is why they're simultaneously softening their position on Palestine and moving to seize the only major social media outlet that isn't US-based (and therefore isn't able to be pressured about 'misinformation' the way that FB, X, reddit, etc are). It's a matter of appeasing us in order to stay in power now while moving behind the scenes to ensure that they control the narrative in future so that they're never again put in a position where they're beholden to the will of voters who think that foreign people are people.

Israel uses a significant amount of the $$ the US gives them to lobby (IOW, bribe) members of the US political parties to support them. Including giving them more $$, in a positive feedback loop. The lobbied polits in effect give themselves money along with what Israel keeps.

From my understanding, we need good relations with israel to have a stable military oresence in the middle east

What stops Biden/US from acting ?

Are red or blue going to lose the elections? They are making money and expanding their power why should they stop?

It would be terrible for the West

We would have to permanently ship around the cape of Africa and abandon oil based economies

It also brings about a large issue for future wars due to strategic positioning

And allies won’t trust the US to defend them so you’re better off aligning with Russia or China
