The U.N. Security Council on Monday unanimously endorsed the landmark nuclear deal between Iran and six world powers and authorized a series of measures leading to the end of U.N. sanctions that have hurt Iran’s economy. But the measure also provides a mechanism for U.N. sanctions to “snap back” in place if Iran fails to meet its obligations. Both U.S. Ambassador Samantha Power and Iran’s U.N. Ambassador Gholamali Khoshroo called the agreement an important achievement for diplomacy, the Iranian promising to be “resolute in fulfilling its obligations” and the American pledging to be vigilant in ensuring they are carried out. 

The resolution had been agreed to by the five veto-wielding council members, who along with Germany negotiated the nuclear deal with Iran. It was co-sponsored by all 15 members of the Security Council. The European Union’s foreign ministers endorsed the agreement later Monday in Brussels and pledged to implement it. MORE
