Trump may look to strengthen, not shred, Iran nuclear deal

By Jonathan Landay, Matt Spetalnick and Parisa Hafezi WASHINGTON/ANKARA (Reuters) - Instead of tearing up the Iran nuclear deal, the Trump administration is exploring how to tighten its enforcement and renegotiate key terms, but it may prove impossible to get other major powers and Iran to consider revising the agreement. Under the 2015 accord between Tehran and six world powers, Iran agreed to curb its nuclear program in exchange for relief from some U.S., European and U.N. economic sanctions. The Trump administration this week signaled a harder but ambiguous line toward Iran by putting the Islamic Republic "on notice" after an Iranian ballistic missile test, and then by imposing economic sanctions on 13 individuals and 12 entities on Friday.. The options the administration is considering include insisting the Vienna-based International Atomic Energy Agency (IAEA), the U.N. nuclear watchdog, get tougher policing Iran's compliance, including demanding access to military sites, according to two sources familiar with the matter.
