Escalating regional tensions culminated on Saturday, February 28, 2026, as the United States and Israel launched a major joint military operation targeting Iran. The coordinated strikes, aimed at multiple sites across the Islamic Republic, represent a significant escalation in the ongoing conflict and raise concerns about further instability in the Middle East. The operation began shortly after 8 a.m. Israel time, according to officials briefed on the attack.
The strikes targeted Supreme Leader Ali Khamenei and President Masoud Pezeshkian, as well as other top regime and military commanders, an Israeli official stated. Targets included Iran’s military infrastructure, symbols of government, and intelligence facilities. Several senior Revolutionary Guards commanders and political officials were reportedly killed, including the commander of Iran’s Islamic Revolutionary Guard Corps, Gen. Mohammad Pakpour, and Iranian defense minister Aziz Nasirzadeh, according to multiple sources familiar with the matter. The United States has confirmed the beginning of “major combat operations in Iran,” framing the campaign as a necessary step to prevent the Iranian regime from threatening American national security interests.
Joint Operation Details
The operation involved Israeli Air Force fighter jets preparing for strikes, including targeting missile launchers aimed at Israel, on February 28, 2026, as reported by the Israel Defence Forces. Footage circulating on social media showed plumes of smoke rising from Tehran, Tabriz, and Sahand following reported explosions. The U.S. And Israel have a long history of security cooperation, formalized through agreements like the Mutual Defense Assistance Agreement of 1952, a General Security of Information Agreement from 1982, a Mutual Logistics Support Agreement in 1991, and a Status of Forces Agreement from 1994, according to the U.S. Department of State.
Speaking on the operation, Hegseth stated, “Only the United States of America could lead this… But when you add the Israeli Defense Forces, a devastatingly capable force…” This highlights the combined military strength brought to bear in the operation. Israel’s strategic location and advanced intelligence capabilities, including radar systems providing early warning of missile launches, are shared with American forces, enhancing the effectiveness of joint operations, as noted by IsraelFactCheck.com.
Legal and Congressional Considerations
The joint military action raises questions about the legal framework governing such operations. Specifically, whether a joint strike requires separate or additional congressional authorization compared to a unilateral U.S. Strike. This issue is currently under debate, with legal scholars examining the extent to which existing security agreements can substitute for explicit congressional approval. The question of whether the 2001 or 2002 Authorization for Leverage of Military Force (AUMF) can be applied to this situation is also being considered.
Iran has already begun retaliating, with strikes reported across the region, as detailed by the U.S. Naval Institute News. Israel declared a nationwide state of emergency, closed its airspace, and moved its hospitals underground in anticipation of potential escalation.
What Comes Next
The immediate aftermath of the strikes remains uncertain. The results of the operation are still being assessed, and the potential for further escalation is high. The international community is closely monitoring the situation, and diplomatic efforts to de-escalate tensions are likely to intensify. The legal ramifications of the joint operation, particularly regarding congressional authorization, will likely be debated in the coming weeks.
