At a special briefing of the UN Security Council held on Tuesday, June 24, focused on Resolution 2231 and the status of the Iranian regime’s nuclear program, senior UN officials and member states voiced escalating concern over Tehran’s continued violations of its international obligations. The session followed a fragile ceasefire between Iran and Israel brokered by the United States, after nearly two weeks of intense military escalation.
Rosemary DiCarlo, UN Under-Secretary-General for Political and Peacebuilding Affairs, emphasized that the ceasefire presents an opportunity to avoid further catastrophe, but warned that the broader diplomatic picture remains bleak. She cited the IAEA’s latest report, which highlighted significant increases in Iran’s stockpile of highly enriched uranium and noted that the agency has lost continuity of knowledge about key aspects of Iran’s nuclear activities due to more than four years of limited access.
“The military escalation between Israel and Iran since June 13, and U.S. airstrikes on Iran’s nuclear facilities on June 21, have severely complicated the path toward restoring full implementation of the JCPOA,” DiCarlo told the Council. She also mentioned Iran’s recent missile strike on a U.S. base in Qatar as another destabilizing move.

U.S. Acting Ambassador to the UN, Dorothy Shea, reiterated Washington’s position that Iran continues to breach both the JCPOA and broader nonproliferation norms. She pointed to Tehran’s weapons transfers to proxies such as the Houthis in Yemen and Hezbollah in Lebanon, as well as its provision of drones to Russia in 2022—actions which directly contravene Security Council resolutions.
Shea defended the U.S. airstrikes on Iran’s nuclear infrastructure as a “precision operation” intended to degrade Iran’s weapons capability, and noted they were followed by a ceasefire coordinated by President Trump. She criticized Council members who “turn a blind eye” to Iranian noncompliance and urged Iran to “seize this opportunity for peace.”
The European Union’s representative, Stavros Lambrinidis, also underscored the urgent need to revive diplomacy, insisting that a lasting solution must be achieved through negotiation, not military confrontation. He warned that Iran’s acceleration of nuclear activity, alongside restricted IAEA oversight, has dangerously eroded the agreement’s viability.

France’s ambassador raised serious doubts about the peaceful nature of Iran’s nuclear program, noting that Tehran has violated nearly all limits imposed under the JCPOA. He stressed that the IAEA no longer has reliable insight into the full scope of Iran’s activities and warned of Iran’s threats to withdraw from the Nuclear Non-Proliferation Treaty (NPT). France, alongside the UK and Germany, signaled readiness to activate the JCPOA’s “snapback” mechanism if no diplomatic progress is made by summer.
Britain’s representative added that Iran’s enriched uranium stockpile now exceeds the JCPOA limit by a factor of 40—well beyond any civilian justification—while Germany called the nuclear program a direct threat to international peace and security.
The clerical regime’s Ambassador Amir Saeid Iravani insisted that Tehran did not start the war, claiming that Iran ceased its military responses once attacks from Israel and the United States stopped. He affirmed the regime’s commitment to diplomacy and insisted that its remedial actions remain within the framework of Resolution 2231 and the JCPOA.

Iravani called on the Security Council to condemn the U.S. and Israeli strikes on Iranian soil, particularly those targeting IAEA-monitored nuclear sites, and urged the Council to prevent future attacks.
The debate over Iran’s nuclear intentions comes as multiple UN member states have begun to express alarm over Iran’s role in regional instability. During the same session, representatives from Germany, the UK, and the EU made clear that Iran’s current trajectory is unsustainable and presents a mounting danger not just to the region but to global nonproliferation efforts.
Despite repeated rounds of indirect talks between Iran and the U.S. in recent months, diplomatic progress remains stalled. A sixth round was canceled altogether due to the outbreak of hostilities.
