Oct 7th to derail Israel-Saudi normalization talks?

Oct 7th happened right as Saudi Arabia was about to normalize relations with Israel. This is an extremely important motive for the attacks as normalization with Saudi Arabia likely would lead to normalization with a slew of other Arab majority countries and reduce aggression towards Israel overall, which is not in the interests of Iran and their proxies, who continually express their desire to annihilate Israel and all the people in it, including over 2 million Arab Israelis that live there.
