US triggers ‘snapback’ process to declare Iran UN sanctions back in force, but world yawns
- United States promises to punish those who violate the sanctions, in move that risks increasing Washington’s isolation
- All other great powers - China, Russia and also America’s own European allies - have challenged claim

The Trump administration declared that all UN sanctions against Iran have been restored, a move most of the rest of the world rejects as illegal and sets the stage for an ugly showdown at the world body ahead of its annual General Assembly.
The administration said that its triggering of the “snapback” mechanism in the UN Security Council resolution that enshrined the 2015 Iran nuclear deal had taken effect at 8pm Eastern time Saturday (8am Hong Kong time Sunday). That is 30 days after Secretary of State Mike Pompeo notified the council that Iran was in “significant non-performance” with its obligations under the accord, known as the Joint Comprehensive Plan of Action, or JCPOA.
“The United States took this decisive action because, in addition to Iran’s failure to perform its JCPOA commitments, the Security Council failed to extend the UN arms embargo on Iran, which had been in place for 13 years,” Pompeo said in a statement released at precisely 8pm.
“In accordance with our rights … we initiated the snapback process to restore virtually all previously terminated UN sanctions, including the arms embargo,” he said. “The world will be safer as a result.”
The White House plans to issue an executive order on Monday spelling out how the US will enforce the restored sanctions, and the State and Treasury departments are expected to outline how foreign individuals and businesses will be penalised for violations.
“The United States expects all UN, member states to fully comply with their obligations to implement these measures,” Pompeo said. “If UN, member states fail to fulfil their obligations to implement these sanctions, the United States is prepared to use our domestic authorities to impose consequences for those failures and ensure that Iran does not reap the benefits of UN-prohibited activity.”

Why can't Iran and the US get along?
But the US move faces stiff opposition from the other members of the Security Council who have vowed to ignore it. They say the US lost legal standing to invoke snapback when President Donald Trump withdrew from the nuclear deal in 2018 and reimposed American sanctions on Iran.
