Biggest U.S. Buildup Since 2003

Trump’s “Operation Epic Fury” has turned the Iran standoff into a full-scale, U.S.-led campaign—one that’s already reshaping Middle East power and testing America’s resolve.

Quick Take

The U.S. and Israel launched coordinated surprise strikes across Iran on February 28, 2026, marking the biggest U.S. regional buildup since 2003.
Iran’s Supreme Leader Ali Khamenei was killed in the initial strikes, creating major uncertainty around Iran’s succession and command structure.
Iran retaliated with missile and drone attacks on Israel, U.S. bases, and regional partners, including an attack reported on Dubai International Airport.
The Trump administration says the mission is focused on stopping an Iranian nuclear weapon, destroying ballistic missiles, crushing naval power, and cutting off proxy support.

What Happened on February 28—and Why It’s Different

U.S. and Israeli forces began coordinated strikes across Iran on February 28, with initial impacts reported in the morning local time. The campaign, described as a surprise operation, quickly stood out for its scale and coordination: Israeli aircraft reportedly hit hundreds of targets in western and central Iran in a single day, while U.S. strikes were conducted from regional basing and carrier-based aviation. Available reporting also indicates Iran’s top leader, Ali Khamenei, was killed in the opening phase.

That single fact—the removal of Iran’s supreme leader—puts this campaign in a different category than past “limited” exchanges. Leadership decapitation can scramble decision-making, accelerate internal power struggles, and reduce diplomatic off-ramps in the short term. The research also indicates the operation was ordered by President Donald Trump while traveling aboard Air Force One, underscoring how quickly the White House intended to act once the decision was made.

The Military Buildup and the Administration’s Stated Objectives

The run-up to the strikes included highly visible signals. Public reporting describes a growing U.S. naval and air presence beginning in January and accelerating through February, including deployments involving major aircraft carriers and supporting warships. By mid-to-late February, the buildup was characterized as the largest U.S. Middle East concentration since the Iraq invasion era. Israel’s participation was also described as historically large, with a massive sortie count and heavy ordnance use in the first 24 hours.

The Trump administration’s messaging is unusually specific for a major military operation. The stated objectives emphasize eliminating Iran’s ballistic missile stockpiles and production, destroying Iranian naval forces, cutting off support for terrorist proxies, and permanently preventing Iran from acquiring nuclear weapons. Senior officials also framed “regime change” as not the primary aim, describing it instead as incidental to degrading Iran’s ability to threaten U.S. forces, allies, and regional stability through missiles, maritime power, and proxy warfare.

Iran’s Retaliation, Regional Spillover, and Civilian Risk

Iran’s response has been immediate and wide-ranging. Reporting indicates missile and drone strikes aimed at Israel, U.S. bases, and U.S.-aligned countries in the region. Iranian military-linked messaging also claimed attacks on numerous U.S. installations, while an Iranian general signaled an intent to continue operations until the U.S. and Israel are “definitively defeated.” Iran’s president publicly suggested Tehran would stop striking neighbors unless attacks came from their territory, but subsequent reporting still described drone activity hitting high-profile sites.

The regional spillover risk is clear even in the limited details available. Saudi Arabia was described as supportive against further Iranian incursions while also restricting use of its airspace. The United Kingdom placed a carrier on heightened readiness, signaling allied concern about a wider conflict. One of the most alarming developments in the research is the reported targeting of Dubai International Airport, which—if sustained—would push the conflict beyond military facilities and into civilian infrastructure, commerce, and international travel.

What’s Known, What’s Not, and Why Americans Should Watch Closely

Key facts are supported across the provided sources: the February 28 start, joint U.S.-Israeli strikes, Khamenei’s reported death, Iranian retaliation, and the U.S. objectives centered on missiles, naval power, proxies, and nuclear prevention. At the same time, critical details remain missing in the material provided, including independent casualty figures, verified damage assessments, and confirmation of which nuclear sites—if any—were directly struck. Those gaps matter because they shape public understanding and congressional oversight.

Politically, the contrast with the prior era is unmistakable in tone and stated intent: this is framed as a decisive campaign rather than a narrow deterrence strike. For conservative Americans wary of endless war, the burden is on leaders to maintain clarity on objectives, timelines, and measurable outcomes. For Americans worried about globalism and weakness inviting chaos, the central question is whether the campaign truly removes Iran’s capacity to threaten the U.S. homeland, troops, and allies without drifting into open-ended nation-building.
