The futile search for a sole authoritative Iranian partner often causes diplomacy to be rejected before it even begins. [When negotiating a nuclear deal with Iran] Turkey and Brazil did not fall into this trap. Instead, they recognized that there are many power centers in Iran — including the supreme leader’s office, the parliament, the president’s circle of advisers, the National Security Council and influential clergymen — all of which need to be included in the process. … Brazil and Turkey built confidence with the relevant Iranian players and won their support for mediation.
