US demands ‘snapback’ of Iran sanctions, setting stage for showdown at United Nations
- Pompeo delivers formal notification to head of UN Security Council, accusing Tehran of violating 2015 nuclear accord
- Demand expected to further isolate US in world body, as other council members say Trump has no authority to invoke snapback after withdrawing from deal

The Trump administration on Thursday formally notified the United Nations of its demand for all UN sanctions on Iran to be restored, citing significant Iranian violations of the 2015 nuclear deal.
Secretary of State Mike Pompeo delivered the notification to the president of the UN Security Council, setting the stage for a showdown in the world body that could lead to a crisis of credibility for its most important and powerful institution. Even before Pompeo presented the council president with the notice, other members rejected the step.
None of the other council members believe the US has the legal right to demand the reimposition, or “snapback”, of sanctions because President Donald Trump withdrew from the nuclear deal in 2018. As such, the demand is expected to further isolate the US at the UN and test the Security Council’s credibility.
In a letter presented to Indonesia’s ambassador to the UN, Dian Triansyah Djani, whose country currently holds the rotating presidency of the council, Pompeo said the US was notifying the body of “significant non-performance” by Iran related to the nuclear deal. As a result, Pompeo said the process leading to the reimposition of UN sanctions had been initiated.

The UN’s nuclear watchdog, the International Atomic Energy Agency, has reported some Iranian violations of the agreement, but Tehran says those are the result of the US violating the accord by withdrawing from it and then reimposing harsh unilateral sanctions.
