UN Security Council Blocks Bid to Halt Iran ‘Snapback’ Sanctions/ Newslooks/ WASHINGTON/ J. Mansour/ Morning Edition/ The UN Security Council rejected a resolution to prevent sanctions on Iran from being reinstated under the 2015 nuclear deal. France, Germany, and the U.K. triggered the “snapback” mechanism, citing Iran’s noncompliance. The move risks escalating tensions between Tehran and Western powers.

Deep Look: UN Security Council Rejects Resolution to Prevent Iran Sanctions Reimposition
UNITED NATIONS — The UN Security Council on Friday voted down a resolution aimed at blocking the return of sweeping sanctions on Iran’s nuclear program, setting the stage for renewed penalties at the end of the month.
South Korea, which currently holds the council presidency, introduced the resolution after weeks of intensive diplomacy. But the measure failed to secure the nine votes needed to stop the “snapback” sanctions outlined under the 2015 Iran nuclear deal.
Only China, Russia, Pakistan, and Algeria supported the resolution. Western nations, led by France, Germany, and the U.K., opposed the move, arguing Iran had failed to meet its obligations.
Western Powers Trigger ‘Snapback’
Last month, France, Germany, and the U.K. formally invoked the snapback mechanism, a provision of the 2015 deal that allows all pre-agreement UN sanctions to be automatically restored if Iran violates terms.
These sanctions include:
- A conventional arms embargo
- Missile development restrictions
- Asset freezes and travel bans
- A ban on nuclear-related technology production
Because the mechanism is designed to be veto-proof, it can only be stopped if the Security Council explicitly votes to block it — something Friday’s failed resolution attempted.
Diplomacy Stalls, Europe Hardens Stance
Despite weeks of backchannel diplomacy, no breakthrough was achieved. Speaking to Israel’s Channel 12, French President Emmanuel Macron said bluntly:
“Yes, I think so because the latest news we had from the Iranians are not serious.”
European Union foreign policy chief Kaja Kallas echoed the urgency:
“The window for finding a diplomatic solution on Iran’s nuclear issue is closing really fast. Iran must show credible steps, cooperate fully with the IAEA, and allow inspections immediately.”
Iran Pushes Back
In response, Iranian Foreign Minister Abbas Araghchi denounced the sanctions as lacking “any legal or logical justification.”
Tehran pointed to a new agreement with the International Atomic Energy Agency (IAEA), mediated by Egypt, that allows inspectors access to all nuclear facilities and requires Iran to account for all nuclear materials.
IAEA chief Rafael Grossi confirmed the deal, saying it provided a framework for inspections and monitoring of Iran’s facilities, though no timetable was disclosed.
Military Escalation Raises Stakes
Tensions were further inflamed by a 12-day war in June, during which Israel, with U.S. support, bombed multiple Iranian nuclear sites. The strikes cast doubt on the state of Iran’s enriched uranium, which international monitors say is close to weapons-grade levels.
What Comes Next
The reimposition of sanctions will likely deepen the rift between Iran and Western powers. In the past, Iranian officials have warned that Tehran could withdraw from the Nuclear Nonproliferation Treaty (NPT) — a step North Korea took in 2003 before developing nuclear weapons.
For now, Iran faces renewed diplomatic isolation and economic penalties as the sanctions are set to snap back into effect at the end of September.
