I hate to say it, but I think Iran needs a few civilian casualties. There is a lot of discontentment with their leaders and they need something to push them over the edge towards an overthrow of the government.

I think the ideal would be to destroy their nuke production (taking out a considerable part of their defense and weaponry as a necessary part) and, thereby, weaken and humiliate their leaders - with the fewest civilian causualties.

As a consequence, giving the opposition a golden opportunity to take over.

I understand this is an optimistic scenario. But I'd posit it as the best possible one.
