Saudi’s probably most influential ruler Faisal was assassinated in 1975 by his very Americanized nephew after blocking oil exports to America for the Palestinian cause. Faisal also nationalized the oil industry and refused to bend the knee to the west.
The assasination was most likely a CIA operation though that does still remain in conspiracy land for about 20 years until we get to see the blacked out lines in the documents.
After Faisa’s assasinationl more pro-America rulers were installed in Saudi. The current “king” MBS arrested many ministers that didn’t fall in line with him when he rose to power.
Throughout his rule MBS did not seem to specifically care for anything else than money. He very much cooperates with America and israel because they are rich, and Palestine is poor. While his population does not agree with this, he buys an insane amount of weapons from America so they can’t do much about it.
While a covert operation might have happened, the MBS government itself is unlikely to have acted against israel because as you can see they are actively aiding israel with Trucknet and other initiatives.
The only reason Saudi doesn’t help israel more openly is because their population isn’t very happy with them supporting a genocidal ethnostate slaughtering Muslims and many of these hypocritical governments are risking a revolution from their population the more openly they support israel.
