The suggestion is that the US has used up its ordnance, especially its anti-missile defenses. That explains the sudden shift, from 'unconditional surrender' to now asking for diplomacy. Iran, for its part, seems to have more missiles and drones still. The drones are simple and cheap to make, and being made of balsa wood are very hard to detect with radar.
Israel is vulnerable. They are small and present an easy target. Iran is not so vulnerable as they present a much larger target. I note that Iran's order of aerial attack is quite clever; to begin with they fired drones without warheads. Nevertheless, they had to be taken down at great expense. Then, gradually Iran ramped up, adding warheads to their drones, then increasing the size of warheads fired by missile. Thus, as Israel's defenses depleted, the weight delivered by Iran grew exponentially.
The uprising within Iran did not eventuate. There appears no groundswell of support for a revolution.
The risk now is that the Persian Gulf may end up being Iran's lake. I read somewhere that the leaders of Kuwait and Bahrain have left their small principalities, with no immediate intention to return. It looks as if they know Iran has emerged the winner.
