Mike Waltz turns tables on Iranian envoy at heated UN meeting

"I have one word only: I advise to the representative of the United States to be polite," Iravani said during the emergency meeting.

The exchange came during an emergency Security Council briefing as the United States, Israel and Iran entered war, with diplomats offering sharply different interpretations of the expanding military campaign and its legality under international law.

He also reiterated that Iran supports armed proxies across the region and has destabilized the Middle East for decades.

Fox News Digital also reported earlier that month on backlash after U.N. Secretary-General António Guterres sent a congratulatory message to Iran marking the anniversary of the 1979 Islamic Revolution, a gesture critics described as "abjectly tone-deaf" given Tehran's human rights record.

The United States is set to assume the rotating presidency of the Security Council on March 1, a role that shifts monthly and gives the presiding country control over the council's agenda and meeting schedule, placing Washington in a key procedural position as tensions continue to mount.
