The nuclear deal between Iran and the six world powers ended a decadeslong crisis that removed sanctions on nearly 80 million Iranians and potentially averted another military confrontation in the Middle East involving the United States. The talks to reach agreement on a deal required bilateral negotiations between Iran and the United States, at the foreign ministerial level, breaking a three-decade taboo on direct negotiations between the two countries.
While it was clear that US President Barack Obama had sought an opening with Iran — he shook hands with Foreign Minister Mohammad Javad Zarif behind closed doors in New York — Iran’s leadership, in particular the supreme leader, Ayatollah Ali Khamenei, never trusted the opposing side enough to allow discussions to go beyond the nuclear file.
