Actually, if it was Realpolitik then the US would engage in a off-shore balancing approach. Not giving unending support to the Saudi-Israel alliance. In fact, the US would gain strategic power by stopping to be so anti Iran. In a more neutral position both nations have far more to lose.
And the Saudis are rightfully panicked about this ever happening and Israel-Saudi alliance spend absurd amount of money in Washington, including think-tanks, employing generals, paying politicians, producing fake intelligence, grand standing and many other methods to make sure not even a slight change in position towards Iran is ever allowed.
As the US, literally putting yourself in the position where you have no other choice then being somebodies little toothless bitch isn't actually good realpolitk. Letting Saudi money so directly influence US politics is idiotically dumb in fact.
You might want to reconsider this take by reading the news of the day: Iran and Saudi Arabia just had a rapprochement brokered by... the Chinese. Whoopsie daisy.
