Talking to know destruction is understood
Entropy,
I'm not sure if your post is directed at mine. So with that caveat aside.
I am not advocating the USA solely talks with Iran, but a far wider community and probably best from outside government. Pugwash for example.
Where are the 'hot lines' to call Teheran in a crisis or when something odd appears on the radar? In a weird way, additional caveat it is decades since I had to think about nuclear deterrence, both sides to know far more than we have nukes and we will hit you. Confidence building in destruction is indeed strange.
