US envoy says returning to Vienna in hope of reviving Iran nuclear pact

Diplomats and analysts say the longer Iran remains outside the deal, the more nuclear expertise it will gain

U.S. Special Envoy for Iran Robert Malley on Sunday said he would soon return to Vienna for the next round of talks on returning to the 2015 Iran nuclear deal, insisting it could still be revived.
 

The Biden administration has been trying to revive the deal, which lifted sanctions against Tehran in exchange for restrictions on its nuclear activities until former President Donald Trump pulled Washington out in 2018. Iran later breached many of the deal's nuclear restrictions and kept pushing well beyond them.

"President (Joe) Biden still wants us to negotiate in Vienna," Malley told MSNBC in an interview
