The Qatari mediators are working on an agreement in which Iran and the United States will make a series of concessions in a five-day series. Iran will reopen the Strait of Hormuz and the United States will lift its naval blockade on Iranian ports. The main roadblocks to this deal are when each side will make its own concessions, and Qatari mediators pushing for a concession on the Iranian nuclear program that the Iranian negotiators are rejecting.
