Hope springs eternal in your breast - and Iran's.
There is absolutely no point talking to someone who does not want to give up what they want. Nukes! With which to dominate the region and blackmail the world.
And if push comes to shove, use one or two of the half dozen they have already to "delete" Israel.
They want more because the six they have is like having six bullets in a revolver and then taking on a gang (the world community). You will take a half dozen down with you but then you are toast.
Also - to whom do you talk? There are suddenly (great!) several at odds schisms in the top clergy, each singing their own tune and refusing to hear any other.
Meanwhile there is the Hojatieh faction of Ahmadi-Nejad and ayatollah Mesbah Yazdi, who believe only death and destruction on a global scale will suffice to bring back their 12th Imam "Redeemer".
Want to talk to them? About what? They are hell bent on total destruction - Armageddon and Apocalypse.
Ahmadinejad ain't interested in talking with the west. The west wants to divert a crisis in the Middle East, and Ahmadinejad wants to build his nukes.
