I doubt Israel could just invade and conquer Iran like that. Having superior equipment is one thing, but actually invading a place will inspire a population to fight against you more than almost anything else, and Iran is a mountainous country that has a population close to 10 times that of Israel. Actually occupying and holding a country like that for any length of time would be a nightmare even for a power like the United States (consider how Afghanistan ended), let alone Israel. They could maybe win a conventional engagement with their superior equipment, sure, and they could do tremendous damage to Iranian infrastructure with bombs or even nukes if they really wanted, but thats not the same as conquering a place.
