Agreement has been signed on July 14, 2015.
Under its terms, Iran agreed to dismantle much of its nuclear program and open its facilities to more extensive international inspections in exchange for billions of dollars’ worth of sanctions relief.
The P5+1 wanted to unwind Iran’s nuclear program to the point that if Tehran decided to pursue a nuclear weapon, it would take at least 1 year, giving world powers time to respond.
Heading into the JCPOA negotiations, U.S. intelligence officials estimated that, in the absence of an agreement, Iran could produce enough nuclear material for a weapon in a few months.
Many experts say that if all parties adhered to their pledges, the deal almost certainly could have achieved that goal for longer than a decade.
Many of the JCPOA’s restrictions on Iran’s nuclear program have expiration dates.
However, the deal has been near collapse since President D. Trump withdrew the U. S. from it in 2018 and reinstated devastating banking and oil sanctions.
- the agreement failed to address Iran’s ballistic missile program and its proxy warfare in the region,
- the sunset provisions would enable Iran to pursue nuclear weapons in the future.
Iran began ignoring limitations on its nuclear program in 2019.
The country accused the U. S.of reneging on its commitments, and faulted Europe for submitting to U.S. unilateralism.
In response to the other parties actions, which Tehran claimed amounted to breaches of the deal, Iran:
- started exceeding agreed-upon limits to its stockpile of low-enriched uranium in 2019,
- began enriching uranium to higher concentrations (though still far short of the purity required for weapons).
- began developing new centrifuges to accelerate uranium enrichment;
- resuming heavy water production at its Arak facility;
- enriching uranium at Fordow, which rendered the isotopes produced there unusable for medical purposes.
The country agreed to provide the IAEA access to 2 suspected former nuclear sites, ending a monthslong standoff over the agency’s investigation into possible undeclared nuclear materials.
President-Elect Biden has pledged to return the United States to the JCPOA if Iran resumes compliance, but it is unclear whether Iran will agree to new negotiations.
