Iran and six world powers sealed a historic accord to curb the Islamic Republic’s nuclear program in return for ending sanctions, capping two years of tough diplomacy with the biggest breakthrough in relations in decades.
Diplomats reached the agreement in Vienna in their 18th day of talks, officials involved in the negotiations said. A final meeting was scheduled to start at 10:30 a.m. local time.
The deal, if approved by the U.S. Congress, promises to end a 12-year standoff that has crippled Iran’s economy and drawn threats of military action from the U.S. and Israel. Full implementation would take months and be contingent on the pace at which Iran meets its obligations. It would enable the oil-rich nation to ramp up energy exports, access international funding and open its doors to global investors.
“This is probably going to go down in history as one of the biggest diplomatic successes of the century,” Ellie Geranmayeh, a policy fellow at the European Council of Foreign Relations, said by phone from London.
