TEHRAN – A senior Iranian lawmaker has said Parliament will fully support any decision by the Supreme National Security Council (SNSC) to withdraw from the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in response to the reactivation of the snapback sanctions mechanism.

Esmail Kowsari, a member of Parliament’s National Security and Foreign Policy Committee, and a member of the IRGC told reporters that while the final decision rests with the SNSC, the legislature stands ready to endorse and implement the country’s broader strategic choices.

“The decision on leaving the NPT lies with the Supreme National Security Council,” Kowsari said. “But if such a decision is taken, Parliament will certainly support it and act in harmony with the nation’s overall policies.”

The lawmaker recalled that the United States unilaterally abandoned the Joint Comprehensive Plan of Action (JCPOA) when then-President Donald Trump left the deal during his first term. “That act meant the U.S. no longer recognized the agreement, rendering it void,” Kowsari said. “The Europeans also failed to honor their commitments, and once again violated their obligations. Now they want to put themselves above the law and take further measures — but this is just an excuse, especially after their defeat in the 12-day war.”

Kowsari noted that the snapback mmechanim would involve the reimposition of sanctions and restrictions on shipping and exports. “But all of these steps have already been taken against us before and led nowhere,” he added.

He emphasized that discussions on a possible NPT withdrawal would take place within the SNSC, with the participation of the Parliament Speaker and the head of Parliament’s National Security Committee. “Once consensus is reached, Parliament will undoubtedly provide full support,” he stressed.

Reflecting on the past decade, Kowsari said the JCPOA had become meaningless because Iran fully complied with its obligations while the U.S. and Europe repeatedly failed to do the same. “Instead of lifting sanctions, they only increased them,” he said. “So if there is to be any legal review, the foundation of the issue has collapsed, and mechanisms like snapback have no legitimacy.”

The lawmaker also issued a warning to Western governments. “If the other side wants to act through force, we also know how to resist. The Islamic Republic of Iran has never started a war or violated agreements — it is they who consistently act unlawfully, trying to achieve their sinister goals through coercion, military power, and bombardment. But over 46 years of the Islamic Revolution have proven that they cannot overcome the Iranian nation — and, by God’s will, they never will.”

Snapback is psychological warfare : Iran judiciary spokesman 

In a separate statement, Judiciary Spokesman Asghar Jahangir condemned the European initiative at the United Nations, describing it as illegitimate and politically motivated.

“In recent days, three European members of the P5+1 have moved to activate the snapback mechanism against the Iranian people,” he said. “This action is contrary to international norms and has no legal validity. Seven years after America’s unlawful withdrawal from the JCPOA, Europe should be held accountable — but instead, it has chosen to activate snapback.”

Jahangir said the measure was aimed more at undermining morale than exerting real pressure. “The snapback mechanism is more of a psychological tool than a genuine threat. The enemy wants to target the spirit of our people through noise and propaganda, but experience has shown that the Iranian nation has bravely resisted sanctions and hardships.”

He also called for vigilance in the information sphere. “In this psychological war, we must adopt smart media strategies,” he stressed. “The media must not allow anyone to take a line that undermines national unity.”
