Zarif in New York Lays Out Options if US Disowns JCPOA

Iran is weighing three options for action in case US President Donald Trump opts out of the 2015 nuclear deal, Foreign Minister Mohammad Javad Zarif told the New Yorker in an interview published on Sunday.
In the first, Tehran could withdraw from the deal, terminate compliance, and resume—even increase—its uranium enrichment, which it agreed to curb under the troubled agreement, Zarif said.
“America never should have feared Iran producing a nuclear bomb,” he said. “But we will pursue vigorously our nuclear enrichment.”
Iran once had the capacity to enrich uranium at 20%, but the deal limited Iran to roughly 3.7% enrichment. 
The UN’s nuclear watchdog, the International Atomic Energy Agency, in the toughest inspections ever imposed on any country, has repeatedly certified Iran’s compliance.
Iran’s second option exploits a dispute mechanism in the deal, which allows any party to file a formal complaint with a commission established to adjudicate violations.
