The deal will grant Tehran sanctions relief in exchange for curbs on its nuclear programme, an Iranian diplomat said on Tuesday.
Under the deal, Tehran would have the right to challenge the UN request and an arbitration board composed of Iran and the six world powers that negotiated with it would have to decide on the issue.
The deal beside being historic is also controversial. Its opponents on Capitol Hill, in Iran, in Israel and the Gulf will continue to campaign against it. But it is practical proof once more that diplomacy is indeed the art of the possible.
