US Strikes Iran: Full Timeline, Targets, and Global Impact in Operation Shield of Judah

What Happened: US Strikes Iran on February 28, 2026

The US strikes Iran began in the early hours of February 28, 2026, when American and Israeli forces launched a coordinated military assault on the Islamic Republic. President Donald Trump confirmed the operation in a video posted to Truth Social, declaring: "A short time ago, the United States military began major combat operations in Iran. Our objective is to defend the American people by eliminating imminent threats from the Iranian regime." (NPR)

The US strikes on Iran represent the largest American military operation in the Middle East since the 2003 invasion of Iraq. According to a U.S. official, dozens of strikes are being carried out by attack aircraft launched from bases across the Middle East and from one or more aircraft carrier strike groups in the Persian Gulf and Arabian Sea. (NBC News)

U.S. officials have described the operation as "not a small strike," emphasizing the scale of what is now unfolding across Iranian territory. Multiple cities including Tehran, Isfahan, Bushehr, Karaj, Kermanshah, Qom, Tabriz, and Hamedan have reported explosions and anti-aircraft fire. (CBS News)

Operation Shield of Judah: Codename and Objectives

The joint US-Israeli military campaign has been designated Operation Shield of Judah. The name references the Tribe of Judah from Jewish biblical tradition, symbolizing strength, leadership, and protection. The U.S. component of the operation has been separately designated "Epic Fury" by the Pentagon. (Pravda EN)

Israeli Defense Minister Israel Katz characterized the operation as preemptive, stating: "Israel and the United States embarked on an operation to remove the existential threat posed by the terrorist regime." He warned that a "missile and drone attack against the State of Israel and its civilian population is expected" in retaliation. (Times of Israel)

The stated objectives of the US strikes on Iran include:

• Destroying Iran's ballistic missile capability and missile production infrastructure
• Preventing Iran from acquiring nuclear weapons
• Neutralizing IRGC (Islamic Revolutionary Guard Corps) command and control infrastructure
• Targeting what Trump called "terrorist proxy networks"
• Protecting regional allies and U.S. forces deployed in the Middle East

Trump went further than military objectives, issuing a direct message to Iranian civilians: "Your hour of freedom is at hand... when we are finished, take over your government, it will be yours to take." He also directed a warning at the IRGC: "Lay down your arms... or you will face certain death." (NPR)

Targets Hit Across Iran

The US strikes on Iran targeted military, nuclear, and government facilities across at least eight cities. Here is a breakdown of confirmed strike locations based on multiple news reports:

Tehran

The capital bore the brunt of the most politically significant strikes. Seven missiles were confirmed striking the district where Supreme Leader Ali Khamenei normally resides, which also houses the presidential palace and the National Security Council. Additional targets in Tehran included:

• The Ministry of Intelligence headquarters
• The Ministry of Defence complex
• The Atomic Energy Organisation of Iran (AEOI) offices
• The Parchin military complex — a site long suspected of nuclear weapons-related testing
• Several IRGC command facilities in southern Tehran

Iranian state television broadcast footage of smoke rising over the city, though it went dark briefly before resuming transmission. (CNN)

Isfahan

Home to a major nuclear facility, Isfahan was targeted both in the June 2025 strikes and again in this operation. The Isfahan complex houses uranium conversion and storage facilities. IAEA Director Rafael Grossi previously noted that U.S. attacks "impacted" tunnel entrances at the Esfahan site during the June 2025 strikes. (Arms Control Association)

Other Confirmed Strike Locations

• Bushehr — Site of Iran's primary nuclear power plant, previously targeted with cruise missiles in June 2025
• Karaj — Location of centrifuge manufacturing facilities
• Qom — Near the deeply buried Fordow enrichment facility
• Kermanshah — Military installations in western Iran
• Tabriz — Military and IRGC facilities in northwestern Iran
• Hamedan — Air base and military installations
• Qeshm Island — Strategic location in the Persian Gulf
• Ilam — Western border military positions

Weapons Systems Deployed

The US strikes on Iran deployed a significant arsenal of precision-guided munitions and standoff weapons, launched from multiple platforms across the theater:

U.S. Weapons Systems

• GBU-57A/B Massive Ordnance Penetrator (MOP) — The 30,000-pound bunker-buster bomb, used for the first time in conventional combat during the June 2025 strikes against Iran's deeply buried nuclear facilities. This weapon was specifically designed to penetrate hardened and deeply buried targets like the Fordow enrichment facility. (Arms Control Association)
• Tomahawk cruise missiles — Launched from Navy ships in the Persian Gulf, including the USS Eisenhower carrier strike group
• Strike aircraft — Fighter and bomber aircraft operating from bases across the Middle East and from carrier decks

Israeli Weapons Systems

• F-35I Adir stealth fighters — Israel's variant of the F-35 Lightning II, used for deep-strike penetration missions
• Precision-guided missiles — Targeting IRGC command infrastructure and nuclear-related facilities

During the June 2025 strikes, Joint Chiefs Chairman Gen. Dan Caine acknowledged that the U.S. lacks the military capability to completely destroy Iran's most deeply buried facilities at Esfahan, raising questions about the effectiveness of the current operation against similar hardened targets.

Full Timeline: How the US Strikes on Iran Unfolded

The following timeline traces the escalation from failed diplomacy to military action, based on reporting from multiple sources:

Weeks Before the Strikes

The Night of the Strikes

How Iran Is Responding to the US Strikes

Iran's response to the US strikes has been swift and multi-layered. The Revolutionary Guard announced retaliatory missile and drone attacks within hours of the first strikes hitting Iranian soil. According to CSIS analyst Benjamin Jensen, Iran's retaliation playbook draws from a well-established menu of options. (CSIS)

Immediate Military Retaliation

Iran launched ballistic missiles toward Israel, triggering air raid sirens across the country. This follows a pattern established in June 2025, when Iran fired 14 ballistic missiles at the U.S. Al-Udeid Air Base in Qatar following U.S. strikes on nuclear sites. During the 12-day conflict with Israel in June 2025, Iran fired approximately 550 ballistic missiles and over 1,000 one-way attack drones — averaging 45 missiles and 83 drones per day. U.S. and Israeli interception rates were estimated at 85-90%. (CSIS)

Iran's Full Menu of Retaliation Options

According to CSIS research, Iran can escalate through five primary channels:

1. Cyberattacks — Iran demonstrated a 700% increase in cyber operations against Israeli targets in 2025 alone. Potential targets include U.S. critical infrastructure, financial institutions, and government systems. Precedent: Operation Ababil (2012-2014) targeted U.S. financial institutions.
2. Targeting unmanned systems — In 2019, Iran shot down an RQ-4A Global Hawk drone near the Strait of Hormuz as a "warning to the United States." This low-escalation option signals resolve without risking a wider war.
3. Maritime retaliation — Iran has a decades-long history of maritime disruption, including mining operations and attacks on commercial shipping. The Strait of Hormuz carries roughly 20% of the world's oil supply, giving Iran enormous leverage.
4. Unconventional warfare — Through proxy groups and covert operations. However, CSIS notes that "decades of investments in counterterrorism and counterintelligence specifically targeting the regime's overseas networks" have limited this capability.
5. Ballistic missile salvos — The most dramatic response option, targeting U.S. bases in Qatar and Bahrain. Iran is unlikely to target Saudi Arabia or Jordan to avoid pulling more regional powers into the conflict.

Iranian Parliament member Ebrahim Azizi issued a stark warning: "Now you've started down a path whose end is no longer in your hands." (NBC News)

The Nuclear Dimension: What Was Actually Destroyed

Understanding what the US strikes on Iran actually accomplished requires looking back at the June 2025 strikes and the intelligence assessments that followed — assessments that often contradicted the administration's public claims.

June 2025 Strikes: Lessons and Gaps

When the U.S. struck Iran's nuclear facilities on June 21, 2025, it targeted three primary sites: the Fordow enrichment facility (deeply buried underground), the Natanz enrichment facility, and the Isfahan uranium conversion and storage complex. The GBU-57A/B Massive Ordnance Penetrator was used in conventional combat for the first time. (Arms Control Association)

Despite Trump's claims that the strikes "obliterated" Iran's nuclear program, a classified Defense Intelligence Agency (DIA) assessment concluded the strikes only set back the program by "maybe a few months." IAEA Director Grossi independently confirmed that Iran could resume uranium enrichment in a "matter of months."

What Remains Intact

Critical concerns identified after the June 2025 strikes:

• Enriched uranium stockpile — VP JD Vance admitted the U.S. "doesn't know" if the enriched uranium stockpile was destroyed. Pre-strike IAEA data from May 31, 2025 showed Iran possessed over 400 kilograms of uranium enriched to 60% U-235 — enough for approximately 10 nuclear weapons if further enriched to weapons-grade 90%.
• Centrifuges — Largely reported as intact after the June strikes
• Technical knowledge — Iran's nuclear expertise cannot be bombed away; the scientific workforce remains
• Deeply buried facilities — Gen. Dan Caine, Joint Chiefs Chairman, acknowledged the U.S. "lacks military capability to destroy deeply buried Esfahan facilities"

Secretary of State Marco Rubio pushed back on skeptics, emphasizing that the destruction of the uranium metal production facility makes weapons development more difficult: "Iran can't do a nuclear weapon without a conversion facility." Director of National Intelligence Tulsi Gabbard estimated the rebuild timeline at "years." (Arms Control Association)

The February 2026 Strikes: Why Again?

The fact that the U.S. is striking Iran again — just eight months after claiming to have "obliterated" its nuclear program — raises questions that multiple news organizations have explored. CNN's analysis, titled "Trump said Iran's nuclear program was 'obliterated.' So why is he looking to strike again?" directly addresses this contradiction. (CNN)

The answer appears to lie in the intelligence community's own assessment: the June 2025 strikes caused less damage than publicly claimed, and Iran moved quickly to protect remaining nuclear materials by relocating them to undeclared sites and cutting off IAEA access.

Oil Prices and Global Economic Fallout

The US strikes on Iran have sent shockwaves through global energy markets. Oil prices surged approximately 15% in overnight trading as markets reacted to the possibility of supply disruptions from one of OPEC's founding members.

Iran sits at the heart of the strategically vital Strait of Hormuz, through which approximately 20% of the world's oil passes daily. Analysts warn that if Iran's oil infrastructure is hit directly and the regime attempts to block shipping routes through the Strait, prices could spike toward $100 per barrel. (CNBC)

Pre-crisis forecasts had Brent Crude averaging $63.85 per barrel in 2026. Bloomberg reported oil had already reached a six-month high before the strikes began, driven by escalation fears in the weeks leading up to the operation. (Bloomberg)

CBS News analysis warned that the conflict could affect American consumers directly through higher gas prices, increased inflation, and higher borrowing costs. (CBS News)

CSIS's separate analysis on oil disruption scenarios outlined multiple levels of potential disruption, from limited price spikes with targeted military strikes to severe global supply shocks if the Strait of Hormuz is contested. (CSIS)

Diplomatic Fallout: How Failed Negotiations Led to War

The path to the US strikes on Iran runs directly through months of collapsed diplomacy. The negotiation timeline reveals a pattern of escalating demands, mixed signals, and ultimately, a decision to use force over continued talks.

The June 2025 Betrayal

Iran's Foreign Minister Abbas Araghchi accused the U.S. of having "betrayed diplomacy mid-negotiation" after the June 2025 strikes interrupted the sixth round of nuclear deal talks. The experience, Araghchi said, made future negotiations "far more complex and complicated." (Arms Control Association)

Iran Cuts Off IAEA Access

On July 1, 2025, a new Iranian law took effect prohibiting cooperation with the International Atomic Energy Agency. President Massoud Pezeshkian told French President Macron that Iran's trust in the IAEA was "broken." Ambassador Amir Iravani stated the agency "cannot have access" to nuclear sites until security assurances were provided.

French President Macron, while sharing nonproliferation goals, criticized the strikes, stating: "There is no legality" in the U.S. military action against Iran's nuclear facilities.

The February 2026 Talks

Despite the wreckage of the June 2025 strikes, the U.S. and Iran returned to the negotiating table in February 2026. Three rounds of talks were held — in Oman and then Switzerland. The U.S. team demanded that Iran destroy its three main nuclear sites (Fordow, Natanz, Isfahan) and surrender all enriched uranium. Special Envoy Steve Witkoff indicated "enrichment is the redline," suggesting Iran would need to abandon enrichment entirely — a demand Tehran has consistently rejected. (Al Jazeera)

Even as talks continued, Trump expressed frustration publicly. The Washington Post reported that a mediator believed a deal was close, but Trump was already moving toward military action. On the final day of negotiations, Trump said: "They don't want to say the key words: 'We're not going to have a nuclear weapon.'" (Washington Post)

Global Reaction to the US Strikes on Iran

The international community has responded with a mix of alarm, condemnation, and cautious support:

• United Nations — An emergency Security Council session has been called. IAEA Director Grossi previously condemned strikes on nuclear facilities as violations of international norms.
• United Kingdom — Had withheld approval for U.S. use of the Diego Garcia base ahead of the strikes, signaling reluctance to be directly involved. (Bloomberg)
• Russia and China — While conducting joint naval drills with Iran in the Strait of Hormuz earlier in February, CSIS analysis notes they have shown "no interest in direct involvement" in a U.S.-Iran military conflict. (CSIS)
• U.S. Congress — The House and Senate have both announced votes on resolutions to restrict the strike authority, setting up a war powers confrontation with the White House. (MS Now)
• Reza Pahlavi — The son of Iran's last shah called for civilian protection and urged Iranian security forces to "join the people rather than defend the regime." (NBC News)
• Israel — Declared a 48-hour nationwide state of emergency, closed airspace to civilian flights, suspended schools, and banned public gatherings in anticipation of Iranian retaliation. (Times of Israel)

What People Are Saying Online

The US strikes on Iran have dominated online discussion, particularly across Reddit's r/worldnews and r/geopolitics communities. Key discussion threads reveal the depth of public concern and analysis.

On r/worldnews, users have been sharing detailed breakdowns of the military hardware involved, analyzing satellite imagery of strike locations, and debating the legality of preemptive strikes under international law. Flight tracking data showing all commercial aviation rerouting around Iranian airspace was widely shared and discussed.

The r/geopolitics community has focused on the strategic implications, with users analyzing CSIS and ACLED assessments, debating whether the strikes will achieve their stated objectives, and comparing the operation to previous U.S. military campaigns in the region. Humanitarian concerns have featured prominently, with many users expressing alarm at the potential for civilian casualties in a country of 88 million people.

On financial subreddits like r/wallstreetbets and r/investing, discussion has centered on oil price movements, defense stock performance, and the broader economic implications of a sustained military conflict in the Persian Gulf. (Reddit Discussion Analysis)

Common themes emerging from the online discourse include:

• Skepticism about the stated objectives given the acknowledged limits of the June 2025 strikes
• Deep concern about escalation potential and the risk of a wider regional war
• Debate over the legality and morality of preemptive military action
• Analysis of oil market disruption scenarios and their impact on everyday consumers
• Questions about Congressional war powers and whether the President has authority for sustained operations

What Happens Next

The US strikes on Iran have set in motion a chain of events whose outcome remains deeply uncertain. Based on expert analysis and historical precedent, several scenarios are possible:

Escalation Spiral

CSIS analyst Benjamin Jensen warns that while leaders initially prefer limited violence to preserve negotiation space, escalation risks increase when "psychological factors like fear or national honor override rational cost-benefit analysis." The frequency of missile exchanges and casualty numbers could trigger what Jensen calls a "losses frame" — risk-acceptant behavior where both sides feel they cannot afford to back down. (CSIS)

Limited Exchange and De-escalation

Historical precedent offers some hope for containment. After the June 2025 strikes, Iran launched 14 ballistic missiles at the U.S. Al-Udeid Air Base in Qatar — with advance warning — and Trump announced a ceasefire call the following day. A similar pattern of symbolic retaliation followed by off-ramp diplomacy is possible.

The Nuclear Question

Perhaps the most consequential long-term outcome: will the strikes delay or accelerate Iran's path to a nuclear weapon? Iranian President Pezeshkian told Tucker Carlson in July 2025 that a deal was possible if nuclear rights were respected, but also questioned how Iran could trust the United States after being attacked during negotiations. The Iranian parliament has drafted NPT withdrawal legislation, though it has not yet been enacted. If Iran withdraws from the Non-Proliferation Treaty, it would remove the last international oversight mechanisms. (Arms Control Association)

Key Variables to Watch

• Iranian missile volleys — Scale and targeting of retaliatory strikes against Israel and U.S. bases
• Strait of Hormuz — Any move to mine or restrict shipping through this critical chokepoint
• U.S. Congressional vote — Whether war powers resolutions gain traction
• Oil prices — Sustained prices above $80-90/barrel would signal markets expect prolonged conflict
• IAEA access — Whether any channel for nuclear monitoring survives
• Russian and Chinese posture — Currently uninvolved, but any shift would dramatically change the calculus

U.S. officials have indicated operations could span "several days," suggesting this is intended as a sustained campaign rather than a single-night strike. Whether it remains limited or expands into a broader conflict may depend as much on Iran's response as on Washington's intentions.
