While Israeli forces successfully targeted critical elements of Iran's nuclear capabilities and eliminated top scientific personnel, key nuclear sites, including the crucial fuel stockpile in Isfahan, have so far evaded direct assault, raising questions about the implications for global nuclear security.

Major Israeli Strikes Against Iranian Nuclear Facilities: What Remains Unscathed?
Despite significant damage to Iran's nuclear program, key components and stockpiles appear to be untouched following recent Israeli airstrikes.
On June 13, 2025, Israeli airstrikes struck multiple Iranian nuclear facilities, resulting in the deaths of several high-ranking military and nuclear figures, alongside extensive damage to one of Iran’s leading uranium enrichment sites at Natanz. However, analysts had anticipated this offensive would focus on the physical location of Iran's near-bomb-grade nuclear fuel, suggesting a limited impact on the overall nuclear program.
The initial round of strikes successfully took out a command center and damaged centrifuge operations, yet the attacks conspicuously avoided targeting a critical stockpile stored at a facility near Isfahan. This location, a significant hub for nuclear development, was omitted from the attack despite widespread expectations it would be a primary target.
Reports indicated that Israeli forces, deploying a range of fighter jets, missiles, and drones, pivoted to engage laboratories involved in transforming uranium gas into metal—a crucial stage in weaponization—rather than striking the actual fuel reserves. Notably, Rafael Mariano Grossi, head of the International Atomic Energy Agency (IAEA), underscored the presence of these fuels during inspections earlier this month.
The rationale behind Israel’s decision to spare the stockpile remains uncertain, especially as Prime Minister Benjamin Netanyahu had previously emphasized its importance in discussions justifying military action. Observers speculate that this restraint may relate to broader geopolitical considerations involving Iran and its allies, as well as the delicate balance of international nuclear agreements.
As the dust settles from these military operations, the global community watches closely to assess the ramifications of the strikes for both Iran's nuclear ambitions and the ongoing discussions surrounding nuclear non-proliferation.
