Be careful what you wish for - there seems to be an automatic assumption that any new leader would be friendly to Israel. Given they're both trying to run the Middle East that's not a given.
Israel isn’t trying to run the Middle East, that’s a three way fight between Turkey, Saudi and Iran. The first two in a struggle for dominance as the major Sunni power and both against Iran as the Shia threat.
An already severely weakened Iran, having already seen its major local allies dismantled and now itself being militarily emasculated, leaves the other two to face off against each other.
Neither poses an existential threat to Israel.
