Door is 'wide open' to negotiation if Trump lifts his sanctions on Iran, Zarif says - NBCNews.com

Trump blasted the accord as the "worst deal ever," saying it granted Iran too many concessions and failed to curb the country’s ballistic missile program.As tensions have flared between Washington and Tehran in recent weeks, Trump has said that he is open to talks with Iran without preconditions but that he was determined to prevent Iran from obtaining nuclear weapons.Zarif said Iran had no interest in securing a nuclear arsenal, though it could have built the bomb if it wanted to."Had we been interested in developing nuclear weapons, we would have been able to do it long time ago," Zarif said.U.S. intelligence agencies concluded previously that Iran abandoned a nuclear weapons program in 2003, but could revive it if and when it decided to.The Trump administration tightened oil sanctions on Iran in April, drastically cutting the country’s oil exports, which are a crucial source of revenue.Iran has responded by taking incremental steps breaching some provisions of the nuclear deal.
