The United States' sanctions policy on Iran is a more effective non-proliferation tool to force Tehran to negotiate a broader deal than the 2015 nuclear deal, U.S. special representative for Iran Brian Hook said on Friday. 'Iran can never acquire a nuclear weapon, it would be catastrophic for the Middle East,' Hook told reporters in a conference call. 'Now that we are outside of the Iran nuclear deal, we are in a much better position to deny Iran a nuclear weapon. 'It allows us to then forcibly respond to Iran's regional aggression and that is what we have done with our sanctions,' Hook said.
