US, Iran inch closer to nuclear deal but high hurdles remain

US officials say they expect to respond to Iran’s comments on a European draft proposal by Wednesday, after which there is expected to be another exchange of technical details followed by a meeting of the joint commission that oversees the deal.
The Biden administration is expected to weigh in this week on Iran’s latest offer to resume its compliance with the 2015 Iran nuclear deal, but neither side is offering a definitive path to revive the agreement, which has been on life-support since former President Donald Trump withdrew from it in 2018.
