I don’t think that Iranians against the regime are necessarily against Iran having Nukes and I doubt Israel is capable of doing enough damage with enough certainty to try.
My only point was that, if soundly attacked by Israel, I would expect it to be so politically damaging to the current unpopular government - that it would be forced to fall by an irate Iranian mob -
Thus throwing another major delay into any weapons program - if not actually allowing a more moderate force to take hold?
