Iran Opposes Grossi’s UN Secretary-General Candidacy, Accuses Him of Failing to Uphold International Law

Iran has publicly opposed International Atomic Energy Agency (IAEA) Director-General Rafael Grossi’s potential appointment as UN Secretary-General next year, accusing him of failing to uphold international law by not condemning US and Israeli strikes on Iranian nuclear sites during the 12-day war between Iran and Israel in June.

During a UN Security Council meeting on Monday, Iran’s Ambassador to the UN, Amir Saeid Iravani, sharply criticized Grossi, calling him unfit” to serve as UN Secretary-General next year, Iranian media reported. 

“A candidate who has deliberately failed to uphold the UN Charter — or to condemn unlawful military attacks against safeguarded, peaceful nuclear facilities … undermines confidence in his ability to serve as a faithful guardian of the charter and to discharge his duties independently, impartially, and without political bias or fear of powerful states,” the Iranian diplomat said. 

With UN Secretary-General Antonio Guterres’ term ending in December next year, member states have already begun nominating candidates to take over the role ahead of the expected 2026 election.

Since the start of the war in Gaza, Israel’s relationship with Guterres has spiraled downward, reaching a low point last year when then-Foreign Minister Israel Katz labeled the UN “antisemitic and anti-Israeli” and declared Guterres persona non grata after the top UN official failed to condemn Tehran for its ballistic missile attack against the Jewish state.

Last week, Argentina officially nominated Grossi to succeed Guterres as the next UN Secretary-General.

To be elected, a nominee must first secure the support of at least nine members of the UN Security Council and avoid a veto from any of its five permanent members — the United States, China, Russia, the United Kingdom, and France. 

Afterward, the UN General Assembly votes, with a simple majority needed to confirm the organization’s next leader.

As head of the UN’s nuclear watchdog since 2019, Grossi has consistently urged Iran to provide transparency on its nuclear program and cooperate with the agency, efforts the Islamist regime has repeatedly rejected and obstructed.

Despite Iran’s claims that its nuclear program is solely for civilian purposes rather than weapons development, Western powers have said there is no “credible civilian justification” for the country’s nuclear activity, arguing it “gives Iran the capability to rapidly produce sufficient fissile material for multiple nuclear weapons.”

With prospects for renewed negotiations or nuclear cooperation dwindling, Iran has been intensifying efforts to rebuild its air and defense capabilities decimated during the 12-day war with Israel.

On Monday, Mohammad Eslami, head of the Atomic Energy Organization of Iran (AEOI), declared that the IAEA has no authority to inspect sites targeted during the June war, following Grossi’s renewed calls for Tehran to allow inspections of its nuclear sites and expand cooperation with the agency.

Iran has also announced plans to expand its nuclear cooperation with Russia and advance the construction of new nuclear power plants, as both countries continue to deepen their bilateral relations.

According to AEOI spokesperson Behrouz Kamalvandi, one nuclear power plant is currently operational, while other two are under construction, with new contracts signed during a recent high-level meeting in Moscow.

Kamalvandi also said Iran plans to build four nuclear power plants in the country’s southern region as part of its long-term partnership with Russia.

During a joint press conference in Moscow on Tuesday, Iranian Foreign Minister Abbas Araghchi reiterated Iran’s commitment to defending the country’s “legal nuclear rights” under the now-defunct 2015 nuclear deal, noting that Tehran’s nuclear policies have remained within the international legal framework.

Iran’s growing ties with Russia, particularly in nuclear cooperation, have deepened in recent years as both countries face mounting Western sanctions and seek to expand their influence in opposition to Western powers.

Russia has not only helped Iran build its nuclear program but also consistently defended the country’s “nuclear rights” on the global stage, while opposing the imposition of renewed economic sanctions.

Russian Foreign Minister Sergey Lavrov has described the reinstatement of UN sanctions against Iran as a “disgrace to diplomacy.”

In an interview with the Islamic Republic of Iran News Network (IRINN), Lavrov accused European powers of attempting to blame Tehran for the collapse of the 2015 nuclear deal, despite what he described as Iran’s compliance with the agreement.

Prior to the 12-day war, the IAEA flagged a series of Iranian violations of the deal.
