The United States is weighing a wide array of ideas on how to revive the Iranian nuclear deal, including an option where both sides would take small steps short of full compliance to buy time, said three sources familiar with the matter, Reuters reported.

Such an approach could slow the deterioration in relations since former US President Donald Trump abandoned the deal in 2018 and freeze Iran’s subsequent violations, which have brought it closer to enriching weapons-grade uranium.

This option could entail Washington allowing Tehran to get economic benefits less valuable than the sanctions relief it received under the 2015 deal in return for Iran stopping, or perhaps reversing, its own breaches of the agreement.

The sources stressed US President Joe Biden has yet to decide his policy. His stated position remains that Iran resume full compliance with the pact before the United States will.

Another source said if the Biden administration concluded it would take too long to negotiate a full return to the deal, it could adopt a more modest approach.
