In 1995, then WJC President Edgar Bronfman, Sr. was reportedly instrumental in blocking a planned deal by the DuPont-owned US oil firm Conoco with Iran. Bronfman was a member of the DuPont board of directors. The deal would have been the first major investment by an oil company in Iran since 1979, when the United States broke off trade with the country after the seizure of the US Embassy in Teheran by Islamic militants. Two months later, the WJC publicly welcomed a decision by US President Bill Clinton to impose a trade embargo on Iran. "We applaud President Clinton's decisive blow against terrorism," declared WJC Executive Director Elan Steinberg. In 2006, after prosecutors in Argentina asked a judge to order the arrest of a former Iranian President Akbar Hashemi Rafsanjani and other members of his government in connection with the AMIA bombing, Bronfman said that "Iran is a state sponsor of terrorism", adding that "the entire international community has a moral responsibility to ensure that Iran is held accountable for its terrorist actions."
