Hossein Mosabian: It is better for Tehran to welcome Vance's proposal, because he was against the war against Iran from the beginning and made many efforts for the Islamabad Memorandum. If there is any chance of ending the current war and crisis, the best options for new negotiations are Vance and Kalibaf or Mohsen Razai. It is better to hold the first round of the new negotiations before the elections.
