I think it's more ideological and about geopolitical power. Maintaining western hegemony in the M.E. requires Israel, and every western nation has dumped a ton of resources into building the nation so no one wants to have that be for nothing, even though Israel has become everything it claims to be against.

Israel will get a blank check as long as the Middle East itself is in turmoil. Bit of a perverse incentive, but it explains both the wests support for the genocidal regime in Israel and the behaviour of Israel itself.

Israel also has some of the most sophisticated intelligence capabilities on the planet. Consider that Ghislaine Maxwell has connections to Israeli intelligence. Having evidence of a bunch of politicians and powerful people having sex with children tends to create a certain element of influence.
