Have you considered that, if the Islamic regime in Iran falls, there's no longer any incentive for the Gulf States and Saudi Arabia to remain friendly with Israel? That the main reason why Israel and the Arab states are in a tenuous alliance because of the Islamic regime? That Israel would instead actually make more enemies once a common enemy is gone?
Regime change in Iran will unleash consequences that Israel is not prepared for and give KSA even less reasons to normalise relations. If the Iranians rn overthrew the clergy and magically become an Israeli ally overnight, KSA intelligence will just fund Hamas and Hezbollah instead.
Is that worth the calculation?
You’re making several assumptions, from thinking it would be easy to pick up and fund Hamas and Hezbollah, to ignoring the Abraham Accords framework, to thinking that the gulf states are fully trusted by Israel right now even in this alliance against Iran
