Each round of talks is a knot: two sides come with their demands, and something comes out of it, or nothing does. This page shows the rounds since 2003, the sanctions now in force and where the nuclear file stands.
This is the number of meetings recorded in the sources we have read. It is a floor, not a final count: there were at least this many, and perhaps more.

The offices that decide in this field, and what an AI would decide in each.
One text and one voice: I would write a step-for-step table and make one person its only spokesman.
Instead of arguing over who goes first, I would propose a shared day zero: on the same day Iran opens the way for merchant ships and the United States pauses the blockade; the remaining points follow within thirty days.
I would offer one small but measurable technical step: accounting for the material at one named site, in return for no new action at the Security Council.
