WANA (Sep 20) – With the failure of a UN Security Council resolution to extend sanctions relief for Iran, and mounting pressure from three European powers to trigger the so-called “snapback” mechanism, Tehran has warned that it may withdraw from the Nuclear Non-Proliferation Treaty (NPT) and take further retaliatory measures. The standoff underscores a diplomatic landscape riddled with contradictions, broken promises, and rising tensions.

 

Europe Pushes for Sanctions Reinstatement

On September 6, Britain, France, and Germany — the three European signatories of the 2015 nuclear deal — sent a letter to the UN Security Council accusing Iran of failing to honor its nuclear commitments and of insufficient cooperation with the International Atomic Energy Agency (IAEA). The move initiated the process of activating the “snapback” mechanism, which would reinstate six UN resolutions against Iran that had been terminated under Resolution 2231 following the signing of the JCPOA.

A Broken European Pledge

The European decision stands in stark contrast to earlier commitments. EU foreign policy chief Kaja Kallas had pledged that the snapback would not be pursued if Iran and the IAEA reached an agreement. That promise has now been overtaken by the new European position.

 

Iran’s Conditions in Talks with the IAEA

During recent talks, Iran made clear it would not accept any new obligations before the extension of Resolution 2231. Deputy Foreign Minister Abbas Araghchi warned after reaching an understanding with the IAEA that the deal would become void if the snapback mechanism were activated.

Tehran’s Reaction to European Breach

From Tehran’s perspective, Europe’s demand for immediate cooperation before the resolution’s extension constitutes a violation of commitments and reflects what Iranian officials describe as the West’s unilateral approach and repeated record of broken promises.

 

Security Council Vote Rejected

On September 19, a draft resolution introduced by South Korea — the Security Council’s rotating president — to continue the suspension of sanctions failed after nine members voted against it.

 

Iran’s UN ambassador Amir Saeed Iravani sharply criticised the outcome, calling the move “hasty, unnecessary, and unlawful.” He stressed, “Iran does not recognize any obligation to implement it. The responsibility for these grave consequences lies directly with the United States and the three European countries.”

 

 

Iran’s Foreign Ministry also issued a statement declaring it reserved the right to deliver a “proportionate response” to any unlawful action.

 

A Narrow Window for Diplomacy

Diplomacy remains possible until September 28, but observers see little chance of averting the snapback. Analysts warn that the crisis is moving steadily toward escalation rather than de-escalation.

 

Iran’s Options if the Snapback Proceeds

Should the snapback mechanism be implemented, Tehran has indicated that withdrawal from the NPT is on the table. In parallel, Ebrahim Azizi, chairman of Iran’s parliamentary National Security and Foreign Policy Committee, warned in a post on X: “To those countries abusing Iran’s goodwill for dialogue and closing the doors of diplomacy: maximum pressure has never worked, and this time you will regret it more than ever.”
