President Donald Trump announced that the United States has begun major combat operations against Iran, targeting Islamic Revolutionary Guard Corps facilities, nuclear infrastructure, and missile programs. The strikes, conducted in coordination with Israel, follow months of military buildup across the region and come amid escalating concerns over Iran’s nuclear advancements and ongoing proxy attacks against U.S. interests and allies.

In his February 28, 2026, address, Trump stated, “A short time ago, the United States military began major combat operations in Iran,” signaling a decisive shift from diplomatic pressure to direct military intervention. The operation reflects a continuation of the administration’s maximum pressure doctrine, now backed by kinetic force after stalled negotiations and repeated warnings to Tehran.

The campaign focuses on degrading Iran’s capacity to develop nuclear weapons and limiting the operational reach of the IRGC, which U.S. officials have long identified as a central driver of regional instability. Coordination with Israel underscores the shared objective of preventing Iran from achieving a nuclear threshold capability, a red line consistently articulated by both governments.

The decision to proceed without congressional approval is likely to spark debate in Washington, but administration officials argue that the strikes fall within the president’s authority to protect U.S. forces and national security interests. Supporters contend that the action restores deterrence after months of Iranian escalation, while critics warn of potential regional fallout.

Reports circulating about the death of Supreme Leader Ayatollah Ali Khamenei have not been independently confirmed, but they add another layer of uncertainty to an already volatile situation. Analysts note that leadership instability in Tehran could either constrain Iran’s response or trigger internal power struggles with unpredictable consequences.

As operations continue, U.S. forces remain on high alert across the Middle East, with additional naval and air assets positioned to respond to retaliatory threats. The administration maintains that the objective is limited and strategic: to neutralize immediate threats while avoiding a broader regional war. The coming days will determine whether Iran seeks escalation or recalibrates under the weight of sustained military pressure.
