On which date did the US attack Iran’s nuclear sites?
A. June 20, 2025
B. June 21, 2025
C. June 22, 2025
D. June 23, 2025
Explanation:
The US attacked Iran’s nuclear sites on June 21, 2025. At the desperate urging of PM Netanyahu, the US conducted a complex attack involving around 125 aircraft, including seven B-2 Spirit stealth bombers, and one submarine that bombed three Iranian nuclear sites at Natanz, Fordow and Isfahan. The attack involved dropping fourteen 30,000 pounds GBU-57 bunker busting MOP (massive ordnance penetrator) at Fordow and Natanz and firing around 75 BGM-109 Tomahawk cruise missiles, mainly at the Isfahan site.
The US Strike on Iran’s Nuclear Facilities: A Turning Point in Middle Eastern Conflict
Introduction
On June 21, 2025, the United States launched an unprecedented attack on Iran’s nuclear facilities, marking a significant escalation in Middle Eastern tensions. This complex military operation, conducted at the urging of Israeli Prime Minister Netanyahu, targeted three critical Iranian nuclear sites and represented the first time a superpower directly attacked another nation’s nuclear installations.
The Military Operation: Scale and Scope
1. Massive Air and Naval Assault
The US operation involved approximately 125 aircraft, including seven B-2 Spirit stealth bombers, and one submarine. The Virginia-based B-2s employed deceptive tactics, with one component heading towards Guam for deception while the other proceeded to the Middle East.
2. Targeted Nuclear Sites
Fordow Site: Containing around 3,000 sophisticated centrifuges in two enrichment halls, the facility was attacked through ventilation shafts at two points using GBU-57 bunker busters. US officials reported the site was “severely damaged but not destroyed.”
Natanz Facility: The largest uranium enrichment center, which had already sustained 11 explosions in Israel’s 2020 clandestine operation. The IDF had previously destroyed its above-ground structures and electric supply on June 13, with US strikes extensively damaging its underground enrichment centrifuges.
Isfahan Complex: Located outside the ancient Isfahan capital, this storage site for near bomb-grade nuclear fuel was targeted with around 75 BGM-109 Tomahawk cruise missiles. Satellite images showed extensive damage to laboratories that convert uranium gas into weapon-grade substance.
Weapons and Tactics Employed
The US deployed fourteen 30,000-pound GBU-57 bunker-busting MOPs (Massive Ordnance Penetrator) at Fordow and Natanz, specifically designed to penetrate heavily fortified underground facilities. The coordinated use of stealth bombers, cruise missiles, and submarine-launched weapons demonstrated the full spectrum of American military capabilities.
Strategic Implications and Precedent Setting
1. Breaking Nuclear Taboos
This attack established a dangerous precedent as the first direct assault by a superpower on another country’s nuclear sites. It rendered the traditional sanctity of nuclear facilities during conflicts null and void, potentially encouraging similar actions in future conflicts.
2. Regional Security Dynamics
The operation fundamentally altered regional security calculations. Countries like India and Pakistan, which regularly exchange locations of their nuclear installations to avoid accidental targeting, now face a changed paradigm under more aggressive regional policies.
Iran’s Response Strategy
1. The Response Dilemma
Iran faced three options: a limited calibrated response, escalating by targeting US bases in the Middle East, or blocking the Strait of Hormuz (carrying over 20% of global oil flows). Iran chose the first option, striking the Al Udaid US base in Qatar in a pre-coordinated manner.
2. Military Effectiveness
Iranian hypersonic missiles successfully penetrated Israel’s multi-layered air defense system, comprising Arrow Missiles, David’s Sling, and Iron Dome. The costly AD system (costing approximately $167 million per engagement) was repeatedly overwhelmed by low-cost Iranian drone and missile combinations.
Assessment of Damage and Effectiveness
1. Limited Nuclear Program Impact
Despite the massive scale of the attack, experts debate whether Iran’s nuclear program was truly eliminated. The main Fordow site, hardened with steel and concrete at approximately 800 meters depth, likely survived significant damage. Iran had probably relocated enriched uranium and critical infrastructure to undisclosed sites beforehand.
2. Iranian Nuclear Capabilities
Prior to the attack, Iran had accumulated over 400 kg of uranium (sufficient for approximately 9 nuclear bombs), enriched up to 60% – just below the weapons-grade enrichment level of 80-90%.
Broader Consequences and Lessons
1. Technological vs. Mass Strategy
The conflict demonstrated, similar to Afghan wars, the success of mass tactics against technological superiority in modern warfare. Iran’s swarming tactics with drones and missiles proved effective against sophisticated defense systems.
2. Nuclear Proliferation Implications
This conflict will likely intensify the global race to acquire nuclear weapons, undermining non-proliferation efforts. A nuclear Iran in the mid to long-term appears increasingly likely, regardless of the current regime.
Regional and Global Impact
1. Israeli Society Under Pressure
The over 600-day conflict left deep scars on Israeli society, with mass exodus of settlers from occupied territories and increased antisemitism globally. Many Israelis fled to Ukraine and Poland, receiving lukewarm welcomes.
2. Ceasefire and Negotiations
On June 24, President Trump announced a complex ceasefire deal after extensive behind-the-scenes negotiations during the 12-day crisis, indicating neither side achieved complete victory.
Lessons for Regional Powers
For countries like Pakistan, this conflict highlighted the critical importance of:
– Investment in drone and missile technologies
– Asset hardening, especially nuclear sites
– Enhanced counterintelligence capabilities
– Strengthened air defense systems
– Air force modernization
Conclusion
The June 21, 2025 US attack on Iran’s nuclear facilities marked a watershed moment in international relations, breaking long-held taboos about targeting nuclear installations. While the immediate military objectives may not have been fully achieved, the operation established dangerous precedents that will influence global nuclear security dynamics for years to come. The conflict demonstrated that in an era where “might is right,” technological superiority alone cannot guarantee victory against determined resistance employing mass tactics and asymmetric warfare strategies.
