A problem with your "voice of reason" is the assumption that it will prevent nukes in Iran or the region. The US people have just offered an object lesson in why deterrent weapons are useful. How capricious they are in diplomacy. And how willing Americans are to withdraw boots on the ground in allied countries. Of course most of that won't be surprising to Iranians.

It's easy, we don't let them have nukes, period. Bombing their underground facilities was absolutely the right thing to do and can be repeated if/when they rebuild. I would go further, finish the job, and insist on complete disarmament of the country.
