What's the point? Persians are friendly towards Israel, it's the religious loonies that hold the power, and they can't be eliminated even with many nuclear strikes. As an armchair internet analyst like myself, I'm 100% sure Iran has nukes just no good delivery mechanism. The few missiles they bought from NK that could have delivered a nuke, they used to randomly shoot at Israel.

The closest Israel came to using nukes was in `73 when it looked like it was about to be overrun by Arab armies on multiple fronts and also many suggested it should have dropped it on Gaza on Oct 7, but that would be seriously stupid even just for revenge, since you can't repopulate the area later.
