Impact of U.S.-Israeli Strikes on Iran's Nuclear Program

Overview of Targeted Strikes
Between 2025 and 2026, military operations conducted by the United States and Israel targeted Iranian nuclear facilities and personnel, raising international concerns regarding the stability of uranium stockpiles and the potential spread of nuclear expertise. The strikes resulted in the deaths of several key Iranian nuclear scientists, including Hossein Jabal Amelian, head of the Organization of Defensive Innovation and Research (SPND), during operations known as Operation Rising Lion and Operation Epic Fury. These actions have led to fears that the Iranian regime's ability to control nuclear materials may weaken, particularly if internal instability arises.
Consequences of Expertise Loss
Experts indicate that while Iran can replace personnel, the specialized knowledge lost due to these targeted strikes is significantly harder to reconstruct. Jim Lamson, a senior research associate at the Center for Nonproliferation Studies, noted that many of the targeted scientists were deeply embedded in critical areas of nuclear work, including the production of highly enriched uranium (HEU) and the design of nuclear explosive devices. The loss of these individuals creates a vacuum in institutional memory that could hinder Iran's nuclear ambitions.
Risks of Internal Instability
Kelsey Davenport, director of nonproliferation policy at the Arms Control Association, stated that the current risk of nuclear terrorism or the movement of nuclear materials to the black market remains low. However, she warned that if the Iranian government were to implode or if significant internal conflict were to occur, the risk of nuclear materials being stolen or diverted to undeclared sites would increase. Additionally, the fear of future military strikes may dampen the motivation of remaining scientists to participate in nuclear weapons programs.
Damage to Infrastructure
The strikes have also targeted a network of sites associated with Iran's nuclear weaponization efforts. Lamson reported that at least 11 weaponization-related sites have been destroyed since 2024, including SPND headquarters and various research universities in Tehran. Despite this damage, Iran retains over 200 kilograms of uranium enriched to 60% at its Esfahan facility, which could potentially be further enriched for weaponization. Iranian Foreign Minister Seyed Abbas Araghchi stated that this material remains buried under debris, with no immediate plans for recovery.
Assessing Long-Term Impact
The long-term strategic impact of these military operations on Iran's nuclear capabilities remains uncertain. Lamson emphasized the difficulty in distinguishing between temporary setbacks and permanent losses in capability. While the visible destruction of Iran's nuclear infrastructure is evident, the actual effects on Iran's intentions and abilities to produce nuclear weapons will require ongoing observation and analysis.
Criticism & Opposition
Critics of the strikes argue that while they may have temporarily disrupted Iran's nuclear program, they could also provoke further instability and escalation in the region. The potential for Iranian scientists to sell their expertise to non-state actors or other nations seeking nuclear weapons raises additional concerns about proliferation risks.
