U.S. and Israel Engage in Military Action Against Iran Amid UN Security Council Tensions

On February 28, 2026, the United States and Israel conducted military strikes against Iran, prompting a heated emergency meeting of the U.N. Security Council. U.N. Secretary-General António Guterres warned that such military actions could trigger an uncontrollable "chain of events" in the Middle East, a region already marked by volatility. Guterres condemned both the U.S. and Israeli strikes and Iran's subsequent retaliatory attacks, which he stated violated the sovereignty of several countries, including Bahrain, Iraq, Jordan, Kuwait, Qatar, Saudi Arabia, and the United Arab Emirates.

During the Security Council meeting, U.S. Ambassador Mike Waltz asserted that the military actions were lawful and necessary to prevent Iran from acquiring nuclear weapons. He emphasized that "the cost of inaction is far greater than the burden of decisive action," framing the U.S. response as a matter of global security. Israel's U.N. Ambassador Danny Danon echoed this sentiment, describing the strikes as a preemptive measure against an existential threat posed by Iran's nuclear ambitions and military capabilities.

Iran's ambassador to the U.N., Amir Saeid Iravani, characterized the U.S. and Israeli actions as "unprovoked and premeditated aggression." He condemned the strikes as war crimes, specifically citing an attack on a school in Minab that reportedly resulted in over 100 child casualties. Iravani called for the Security Council to hold the U.S. and Israel accountable for their actions and demanded an immediate cessation of hostilities.

The emergency session saw a clash of words between U.S. and Iranian representatives, with Iravani urging Waltz to maintain decorum. Waltz countered by highlighting the Iranian regime's history of oppression. Meanwhile, Russia's U.N. Ambassador Vassily Nebenzia condemned the airstrikes and called for a return to diplomatic negotiations, a sentiment echoed by China's U.N. Ambassador Fu Cong. The leaders of Britain, France, and Germany also urged for a resumption of U.S.-Iranian talks regarding Tehran's nuclear program, emphasizing the need for a negotiated solution.

The assassination of Iran's Supreme Leader, Ali Khamenei, reportedly confirmed by Iranian state media, raises concerns about the potential for prolonged conflict and further retaliatory actions from Tehran. The U.N. Security Council's ability to mediate the situation is under scrutiny, with calls for immediate action to prevent escalation. As the U.S. prepares to assume the presidency of the Security Council, the international community watches closely, aware that the current military actions could have far-reaching consequences for regional and global stability.
