At Trump's behest, J. Di Vance sent a letter to Mosan Razai, head of Iran's Supreme National Security Council, calling for the resumption of peaceful negotiations. The purpose of this move is to prevent a possible new US attack on Iran after next week's midterm elections. The negotiations focused on establishing a framework for dialogue, rather than a specific peace proposal. Washington demands nuclear concessions, while Tehran seeks an immediate opening of economic opportunities. Source: The Wall Street Journal.
