European states have not yet taken a final decision to activate the “snapback mechanism” against Iran. Instead, they have initiated a 30-day process that could eventually lead to the return of international sanctions on Tehran.
The snapback mechanism is a special clause in UN Security Council Resolution 2231, allowing any party to the nuclear deal to refer the matter to the Council if it claims Iran has committed a serious breach of its commitments. After completing the necessary procedures, UN sanctions—lifted under the nuclear agreement—could be automatically reimposed within 30 days.
A Timed Path, Not an Immediate Decision
According to Al Jazeera’s Tehran bureau chief, Abdel Qader Fayez, the step taken so far is a process, not an instant decision. He explained that the three European powers—Britain, France, and Germany—have informed the Security Council, which now has 30 days to attempt a diplomatic solution centred on renewing the Iranian nuclear deal.
If no solution is reached within that period, sanctions will automatically “snap back” as stipulated in Resolution 2231. Fayez emphasised that this development presents the international community with a decisive juncture, one that could significantly shape the future of diplomacy with Iran for years to come.
Diplomatic Struggle at the Security Council
The Security Council currently witnesses a sharp diplomatic standoff. Russia and China are pushing strongly for a six-month extension of the nuclear agreement. Such an extension, if approved, could give all parties breathing space to retreat from hardened positions and return to the negotiating table.
Fayez noted that the potential extension would allow both the U.S. and Iran time to create a more rational atmosphere for talks. Iran, while previously rejecting European proposals, has hinted at openness to an extension if it comes from its allies, Moscow and Beijing.
Europe’s “Carrot and Stick” Strategy
Meanwhile, Al Jazeera’s Berlin correspondent, Ayman al-Zubeir, reported on the coordinated European stance. Germany, France, and Britain have agreed to employ a carrot-and-stick approach toward Iran.
European foreign ministers have repeatedly said that activating the snapback mechanism does not mean the end of diplomacy. Instead, they see it as a pressure card that strengthens their hand without entering direct negotiations. It also preserves the option of imposing additional sanctions targeting Iran’s banking, energy, and defense sectors.
Yet this strategy carries serious risks. Once the snapback mechanism is fully implemented, Europe would lose its leverage, potentially pushing Iran away from negotiations altogether. This scenario would collapse the nuclear deal and leave no international framework for handling Iran’s nuclear program, leaving the file to direct U.S.–Iran dealings alone.
Mounting Tensions with the IAEA
These developments come at a time of heightened tension between Iran and the International Atomic Energy Agency (IAEA). Technical disputes have complicated chances of reaching solutions, making tomorrow’s Security Council session—according to Fayez—a decisive moment for the fate of diplomacy.
Earlier this year, the Europeans and the U.S. agreed on an end-of-August deadline to trigger the snapback if Iran failed to meet key conditions:
- Resume negotiations with Washington on its nuclear program,
- Grant IAEA inspectors full access to nuclear sites,
- Clarify the fate of more than 400 kilograms of highly enriched uranium.
Tehran had previously threatened to withdraw from the Nuclear Non-Proliferation Treaty (NPT)—which ensures peaceful use of nuclear energy—if Europe moved to reimpose UN sanctions.
U.S. Military Pressure
It should be recalled that in June, the U.S. launched strikes on three Iranian nuclear sites. President Donald Trump even claimed Washington had “destroyed Iran’s nuclear program completely.” However, subsequent intelligence assessments from within Washington cast doubt on the accuracy of his claims.
Conclusion
The coming days are critical. Between Europe’s snapback threat, Russia and China’s extension push, and U.S. military pressure, the future of Iran’s nuclear file hangs in the balance. Either a fragile diplomatic extension is secured, or sanctions return in full force—pushing the region into yet another cycle of confrontation.
