US-Iran Conflict Escalates as Trump Authorizes Large-Scale Military Action Against Iranian Targets

On February 28, 2026, the United States and Israel executed synchronized military actions against Iran, escalating tensions in the region. The operation, designated ‘Operation Epic Fury,’ was announced by President Donald Trump, who declared the U.S. had begun ‘major combat operations’ to neutralize threats from the Iranian government. Israeli Prime Minister Benjamin Netanyahu characterized the strikes as a collaborative effort to ‘eliminate the existential threat posed by the Iranian regime.‘

U.S.-Israel Strikes on Iran: Objectives and Immediate Impact

The strikes focused on Iran’s nuclear facilities, ballistic missile programs, and military infrastructure, including the Revolutionary Guard Corps (IRGC). NBC News reported explosions in central Tehran, with Iranian state media confirming missile launches toward Israel. Israeli air defenses intercepted the projectiles, and sirens were activated across the country. The Israeli Defense Ministry declared a state of emergency, advising civilians to seek shelter. U.S. President Trump stated the objective of ‘destroying Iran’s missiles and dismantling its missile industry to the ground,’ while also asserting the need to ‘ensure Iran does not acquire a nuclear weapon.’

The operation was preceded by a significant U.S. military buildup, including the deployment of two aircraft carriers—the USS Abraham Lincoln and USS Gerald R. Ford—alongside escort ships and over 100 aircraft. This marked a contrast to prior U.S. involvement in the region, which had emphasized diplomatic efforts to limit Iran’s nuclear program. Trump’s administration had consistently warned Iran against resuming uranium enrichment, citing its role as the ‘world’s number one state sponsor of terror.‘

Iranian Response and Regional Reactions

Iran’s Revolutionary Guard Corps (IRGC) launched a counterattack, firing drones and missiles toward Israel. Iranian state media reported that the U.S. Navy’s Fifth Fleet service center in Bahrain was targeted by a missile, though no casualties were confirmed. The Iranian government also restricted internet and mobile phone services nationwide, with connectivity dropping to 4% according to NetBlocks, a monitoring group. This blackout resembled measures taken during prior protests in Iran, which had been violently suppressed by authorities.

Iranian President Masoud Pezeshkian was reported ‘safe and sound‘ by state media, but Supreme Leader Ayatollah Ali Khamenei’s location remained unclear. Hardline Iranian MP Alaeddin Boroujerdi warned that Iran would retaliate ‘without red lines,’ vowing ‘regret-inducing’ strikes against U.S. and Israeli targets. Meanwhile, Reza Pahlavi, the son of Iran’s deposed shah, urged Iranians to ‘take back their country,’ framing the strikes as a ‘humanitarian intervention’ to dismantle the regime.

Regional reactions were varied. Jordan conducted air sorties, while Lebanon’s Prime Minister called for caution. The African Union urged de-escalation, and Qatar declared its situation ‘stable and safe.‘ Israel’s closure of airspace and activation of civil defense protocols underscored the gravity of the situation.

Historical Context and Diplomatic Failures

The current conflict follows a 12-day war in June 2025, when Israel launched strikes against Iranian nuclear sites, prompting Iran to retaliate with missile attacks on U.S. and Israeli targets. The U.S. military, under Trump’s direction, conducted airstrikes in June 2025, later described as ‘Operation Midnight Hammer.’ Iran claimed its nuclear facilities were ‘completely and fully obliterated,’ but the International Atomic Energy Agency (IAEA) reported that Iran’s nuclear material remained ‘in large quantities,’ albeit less accessible.

Diplomatic efforts to reach a nuclear deal had stalled, with Iran refusing to abandon its uranium enrichment program. Trump had previously threatened military action if Iran did not agree to ‘no nuclear weapons,’ a stance echoed in his February 2026 address. The U.S. had also warned Iran against supporting proxy groups like Hamas, which it blamed for the October 7 attacks on Israel. Despite these pressures, Iran’s Supreme Leader, Ayatollah Khamenei, warned of a ‘regional war’ if the U.S. escalated tensions.

Military and Strategic Implications

The operation reflects a broader shift in U.S. strategy toward Iran, moving from containment to direct confrontation. Pentagon planners had briefed Trump on a range of options, including cyberattacks and psychological campaigns, which could be deployed alongside traditional military strikes. The targeting of the IRGC and Kham, the Supreme Leader’s inner circle, suggests a desire to destabilize Iran’s leadership structure. However, analysts caution that such actions risk drawing in regional allies like Russia and China, complicating the conflict further.

The strikes also highlight the growing role of technology in modern warfare. The use of AI-generated imagery by Iranian officials to warn of U.S. military threats underscores the evolving nature of propaganda and deterrence. Meanwhile, the internet blackout in Iran raises questions about the regime’s ability to control information during crises, a critical factor in its response to external pressures.
