(VOVworld) - Rejecting the Iran nuclear deal would lead to diplomatic isolation for the United States and significantly undermine Washington's ability to achieve other foreign policy goals, the US envoy to the United Nations said Thursday. In an article published on the Politico website, US Ambassador Samantha Power said diplomats from the 193 member states of the United Nations are tracking the heated US congressional debate on the deal. Power said "From this vantage point, I believe that rejecting this deal would significantly weaken our ability to achieve our broader foreign policy goals – most of which in 2015 require us to mobilize broad international coalitions". Power said rejecting the agreement, which calls for lifting most sanctions against Iran in exchange for curbs on its nuclear program that will be in place for at least 10 years, would hurt the United States more than it hurts Iran.
