The Middle East conflict reached a new peak on Saturday, June 21, 2025, when the United States, under President Donald Trump’s command, conducted airstrikes on three Iranian nuclear facilities: Fordow, Natanz, and Esfahan. The operation, described by Trump as “highly successful,” marks the U.S.’s direct entry into the war between Israel and Iran, which began on June 13. The American offensive, using B-2 Spirit bombers and Tomahawk missiles, escalated regional tensions, prompting a fierce response from Iran’s state media, which declared “every American citizen or military in the region” a legitimate target. The action follows weeks of air clashes between Israel and Iran, with both sides targeting strategic infrastructure. The attack reflects Trump’s renewed “maximum pressure” policy against Tehran, aimed at neutralizing Iran’s nuclear program, accused of nearing weapons-grade capability.
The U.S. decision to intervene directly came after pressure from Israel, a close ally, which had already bombed Iranian nuclear targets but lacked the firepower to hit fortified sites like Fordow. Built under a mountain at a depth of about 80 meters, Fordow is considered the heart of Iran’s nuclear program, designed to withstand airstrikes. Trump, on his Truth Social platform, celebrated the operation, stating that “Fordow is gone” and that the offensive represents a “historic moment” for the United States, Israel, and the world.
The American strikes, however, triggered a wave of threats from Iran. Iranian state television aired a graphic titled “Within Iran’s firing range,” highlighting U.S. military bases across the Middle East. A commentator addressed Trump directly, stating, “You started it. We will finish it.” The belligerent rhetoric underscores the gravity of the situation, with Tehran vowing reprisals against U.S. forces in the region.
- Targets hit: Fordow, Natanz, and Esfahan, three of Iran’s key nuclear facilities.
- Means used: B-2 Spirit bombers with “bunker buster” bombs and 30 Tomahawk missiles.
- Context: Escalation of the conflict started by Israel, which accuses Iran of pursuing nuclear weapons.
- Iranian response: Threats against American citizens and military, spotlighting regional bases.
Fordow: Iran’s nuclear core
The Fordow facility, located near Qom, is a cornerstone of Iran’s nuclear program. Built in the early 2000s, the plant was designed to operate uranium enrichment centrifuges in an underground complex shielded by rock and soil. Its strategic location, about 80 to 90 meters below ground, makes it nearly impervious to conventional attacks. According to the International Atomic Energy Agency (IAEA), Fordow has been used to enrich uranium to levels as high as 83.7%, just a technical step below the 90% needed for a nuclear bomb.
The U.S. attack on Fordow involved six GBU-57 Massive Ordnance Penetrator (MOP) bombs, known as “bunker busters.” These weapons, exclusive to the U.S., weigh 13.6 tons and can penetrate up to 61 meters of rock before detonating. Military sources indicate the bombs were dropped sequentially to maximize destruction of the complex. The operation was meticulously planned, with B-2 bombers departing from bases in Missouri and refueled in flight before entering Iranian airspace.
Despite Trump’s claim that “Fordow is gone,” Iran downplayed the damage. The state-run IRNA news agency stated that the facilities were evacuated beforehand and enriched uranium had been removed, suggesting limited material impact. However, experts note that the destruction of centrifuges and critical infrastructure could delay Iran’s nuclear program by years, unless undetected secret facilities exist.
Natanz and Esfahan: strategic targets
In addition to Fordow, the Natanz and Esfahan plants were also hit. Natanz, located in central Iran, is the country’s largest uranium enrichment facility. Already targeted by Israeli strikes in early June, the site sustained further damage from U.S. Tomahawk missiles. Esfahan, meanwhile, houses laboratories that convert uranium into weaponizable forms and stores uranium enriched to 60%, close to bomb-grade levels.
The strikes on these sites reflect a joint U.S.-Israel strategy to dismantle Iran’s nuclear capabilities. While Israel focused on smaller-scale attacks, the U.S. brought superior firepower, using weapons capable of hitting fortified targets. Coordination between Washington and Tel Aviv was confirmed by Israeli officials, who said they were notified of the U.S. operation in advance.
- Natanz: Main enrichment hub, with centrifuges damaged in prior attacks.
- Esfahan: Stores enriched uranium and hosts labs for nuclear material conversion.
- Impact: The destruction could set Iran’s nuclear program back years, analysts say.
- Coordination: U.S. and Israel worked together, with prior notification to Tel Aviv.
Iranian reactions and escalation risks
Iran’s response to the attacks was swift and aggressive. Beyond state TV’s statements, the Iranian government vowed retaliation, though it provided no specifics. The Tasnim news agency, linked to the government, reported partial damage to the Fordow complex but claimed nuclear operations continue at other sites. Iranian officials also accused the U.S. and Israel of violating the Nuclear Non-Proliferation Treaty, insisting their nuclear program is purely peaceful.
Tehran’s belligerent rhetoric worries experts, who fear an uncontrolled escalation. U.S. bases in Iraq, Syria, and the Persian Gulf are within range of Iranian missiles, and Iran-backed groups like Hezbollah could intensify attacks on Western targets. Iran’s Deputy Foreign Minister, Saeed Khatibzadeh, had previously warned that U.S. involvement would unleash “hell across the region.”
Iran’s Supreme Leader, Ayatollah Ali Khamenei, has yet to comment officially on the attacks, but his influence will be critical in shaping Tehran’s response. Meanwhile, Iran’s population faces growing internal pressure, with protests against the regime gaining momentum amid economic hardship and the escalating conflict.
Conflict context and Trump’s pressure
The U.S. attack comes amid heightened tensions in the Middle East. The conflict between Israel and Iran began on June 13, when Israel launched strikes on Iranian nuclear and military targets, accusing Tehran of being weeks away from a nuclear bomb. Iran retaliated with missiles on Israeli cities, including Tel Aviv and Jerusalem, while Israel escalated its bombings.
Trump, who withdrew from the Iran nuclear deal in 2018 during his first term, reinstated “maximum pressure” in 2025. In February, he demanded Tehran abandon its nuclear program, threatening military action if negotiations failed. In the week before the attacks, Trump ramped up his rhetoric, claiming to know Khamenei’s location and hinting his patience was wearing thin.
- Recent timeline:
- June 13: Israel attacks Iranian nuclear facilities.
- June 17: Iran fires missiles at Israeli cities.
- June 19: Trump issues a two-week ultimatum to Iran.
- June 21: U.S. bombs Fordow, Natanz, and Esfahan.
Regional and global implications
The U.S. entry into the conflict raises the risk of a large-scale regional war. Countries like Saudi Arabia, Turkey, and Egypt, with complex ties to Iran, could be drawn into the crisis, especially if Tehran retaliates against U.S. bases. Russia and China, Iran’s allies, have voiced concern over the escalation but have not announced concrete actions.
The IAEA, which monitors Iran’s nuclear program, confirmed damage in Esfahan but said there’s no immediate risk of radiological leaks. The agency criticized the attacks, warning that military actions on nuclear sites violate international norms. The IAEA’s board of governors, comprising 35 nations, had already declared in 2025 that Iran violated non-proliferation obligations, fueling justifications for Western strikes.
Domestically, Trump’s decision faces pushback from anti-interventionist groups, who fear a prolonged Middle East conflict. However, Republican allies, like House Speaker Mike Johnson, praised the operation, saying it reinforces Trump’s stance against a nuclear Iran.
What to expect in the coming days
The attack’s aftermath hinges on Iran’s response. Analysts believe Tehran may opt for asymmetric attacks, using proxies like Hezbollah or militias in Iraq, rather than direct confrontations with the U.S. Iran’s ability to rebuild its nuclear program will also be a key factor, particularly if secret facilities exist.
Meanwhile, diplomatic pressure is mounting. Iran’s Foreign Minister, Abbas Araqchi, met with European leaders in Geneva the day before the attack, seeking a conflict resolution. The talks collapsed after the U.S. offensive. Countries like the UK, France, and Germany expressed concern over the escalation but refrained from directly criticizing the U.S.
The situation remains volatile, with the Middle East on the brink of a broader conflict. The rhetoric from both sides suggests that peace, as advocated by Trump in his statements, is far from achievable.
