NEW YORK – The sharp clash between US Ambassador to the United Nations Mike Waltz and Iran’s Permanent Representative Amir Saeid Iravani took center stage during an emergency United Nations Security Council meeting on February 28, 2026. Middle East tensions spiked after joint US-Israeli strikes on Iranian targets (Operation Epic Fury), followed by Iran’s counterattacks across the region.
Called under the agenda item, “The situation in the Middle East,” the session focused on how close the region may be to a wider war. Reports cited civilian casualties, the reported death of Iran’s Supreme Leader Ayatollah Ali Khamenei in the strikes, and urgent pleas to calm the crisis from UN Secretary-General António Guterres.
US Ambassador’s Showdown at the UN Security Council
The exchange between US Ambassador Waltz and Iravani became one of the most personal and direct arguments seen at the UN in recent years. It came late in the meeting, after Iravani denounced the US-Israeli operation as “unprovoked and premeditated aggression.” He said it violated Iran’s sovereignty, killed and injured hundreds of civilians (including strikes he called deliberate attacks on residential areas), and amounted to war crimes.
Soon after, Iravani asked to speak again and delivered a pointed message to the US envoy.
“I advise the representative of the United States to be polite,” Iravani said. “It will be better for yourself and the country you represent. Thank you.”
Waltz responded right away using his right of reply. He rejected the warning and aimed his remarks at Iran’s leadership.
“This representative sits here, in this body, representing a regime that has killed tens of thousands of its own people, and imprisoned many more, simply for wanting freedom from your entire tyranny,” US Ambassador Waltz said. He also said he would not “dignify this with another response,” while repeating the US view that the strikes were legal and needed to protect allies, limit proxy groups, and stop Iran from getting nuclear weapons.
The back-and-forth drew audible reactions in the room. It also spread quickly through international media, highlighting just how deep the hostility remains between Washington and Tehran during the current crisis.
What Sparked the Emergency Meeting: US-Israel Strikes and Iran’s Response
The Security Council met after early morning airstrikes on February 28, 2026. The United States and Israel carried out the attacks together, hitting Iranian nuclear facilities, missile locations, and other military sites. US officials described the mission as a firm response to Iran’s long-running threats and its backing of regional proxy forces that have targeted US and Israeli interests.
Iranian state media reported major damage and casualties. During the session, Iravani said “hundreds of civilians” were killed or wounded on the first day. Iran then answered with missile and drone strikes on Israel and on US bases in several Middle Eastern countries, including reported strikes in the Gulf region.
Reports also said the strikes killed Supreme Leader Ayatollah Ali Khamenei. Iranian state media later confirmed that account, which raised fresh concerns about leadership succession and stability inside Iran.
This was the second major US-Israeli action against Iran in under a year. It followed a June 2025 round of strikes that included the US bombing of nuclear sites.
Guterres Presses for De-Escalation
UN Secretary-General António Guterres opened the meeting with a warning about the risks of escalation. He criticized the growing use of force and said it threatened international peace and security.
“The use of force by the United States and Israel against Iran, and the subsequent retaliation by Iran across the region, ignite a chain of events that nobody can control in the most volatile region of the world,” Guterres said. He also stressed that the UN Charter bars threats or force against a state’s territorial integrity.
Guterres called for:
- An immediate halt to hostilities
- A return to negotiations to pull the region back from the edge
- Full respect for international law to reduce the risk of a broader war with severe costs for civilians and regional stability
He warned that the other path leads to “a potential wider conflict” that could devastate the Middle East and spread far beyond it.
International Responses and Pressure to Show Restraint
Many Security Council members and observers weighed in during the session:
- Russia and China criticized the US-Israeli strikes as “unprovoked aggression” and backed Iran’s claim to self-defense under Article 51 of the UN Charter.
- European countries, including France (whose president requested the meeting), pushed for restraint and stronger protection for civilians.
- The European Union said it was deeply concerned and urged all sides to stop military operations.
- Several non-aligned states also called for an immediate ceasefire and UN-led talks.
The council did not adopt a resolution. Still, the meeting made the split clear, with the United States defending its actions as defensive and lawful.
What This Could Mean for Middle East Stability and Global Security
The argument at the UN reflects how fragile diplomacy looked in 2026. Several risks stand out:
- The fighting could widen and pull in more players, including proxy groups in Lebanon, Yemen, Iraq, and Syria.
- Threats in the Gulf could shake global energy markets.
- Attacks on Iranian facilities raise fears about nuclear escalation.
- Iran could face internal unrest after the reported loss of its supreme leader.
Analysts have warned that if leaders don’t move fast to cool tensions, the cycle of strikes and counterstrikes could spiral into a larger war. That could also draw in major powers and trigger a major humanitarian crisis.
When the meeting ended, diplomats stressed the need for urgent back-channel contacts to restore calm. The US Ambassador Waltz-Iravani confrontation grabbed headlines, but the military situation on the ground continues to shape what comes next.
