VIENNA - Iran's leadership and state-run media have embraced news of an historic nuclear agreement with world powers as a "good" deal for the Islamic Republic.The deal, according to local press, respects "red lines" in the negotiations set out by the country's supreme leader, Ali Khamenei, who said he would forbid international access to Iranian military sites just last month. "Constructive engagement works," Iranian President Hassan Rouhani said with a message on Twitter. "With this unnecessary crisis resolved, new horizons emerge." Iranian press outlets said that the deal allowed Iran to retain all of its nuclear facilities. One such organization, IRNA, said "none will be stopped or eliminated;" that "Iran will continue enrichment" and that "research and development on key centrifuges will continue."In Vienna, preparing for a press conference, Iranian Foreign Minister Mohammad Javad Zarif said the deal is "not perfect" but is nevertheless an "historic moment" for Iran and the West.And the European Union's foreign policy chief, Federica Mogherini, said the deal may hail a new chapter in international relations.Israel's Prime Minister Benjamin Netanyahu has called the deal a "mistake of historic proportions."
