From Airstrikes to Poison: How Mossad Eliminated 13 of Iran’s Nuclear Masterminds in 18 Years

International News: Since 2007, Israel’s intelligence agency has orchestrated a series of high-profile assassinations of Iran’s top nuclear researchers. On Friday morning, Mossad claimed responsibility for killing six scientists in coordinated attacks in Iran. Among the slain are renowned figures like Ardeshir, Majid Shahriyari, F. Abbasi, Mostafa Roshan, and Fakhrizadeh. These names represent the architects behind Iran’s nuclear pursuits, and each strike has chipped away at Tehran’s atomic expertise.

Mossad didn’t rely solely on bombs. Their operations included explosive ambushes, covert poisonings, and remote detonations. The agency adapted its tools depending on the target’s defenses, moving from aerial strikes to chemical methods when needed.

Coordinated Intelligence on the Ground

These assassinations required meticulous preparation. Deep undercover assets infiltrated Iran’s circles to identify movements and vulnerabilities. Mossad operatives collected intel via surveillance, informants, and digital espionage to map out each scientist's routines. Every operation sent a strong message: Tehran’s nuclear ambitions come at a deadly cost. By reducing the number of key personnel, Mossad slowed Iran’s nuclear momentum and sowed paranoia within its scientific community.

Global Diplomatic Fallout

Each assassination triggered international tension. Iran retaliated with furious rhetoric and threats of revenge. Western governments issued travel alerts in the region. Yet Israel remained silent, prolonging the aura of mystery around each strike. This was no quick blitz. Over 18 years, Mossad has maintained a steady, methodical campaign. The timing and choice of weapon—be it drone, car bomb, or toxin—were decided case by case. This long view allowed them to dismantle Tehran’s core nuclear planning cells.

Iran's Response: Retaliation or Reinforcement?

While Iran condemned every killing, the impact is deeper: a simmering distrust within its labs and increased security around remaining scientists. Tehran has also doubled down on nuclear secrecy, dispersing critical research to hidden and protected locations. Mossad’s operation is not just a military gambit—it’s psychological warfare. By eliminating 13 top scientists using varied methods, Israel has sent a shudder through Iran’s nuclear program. This quiet campaign raises thorny ethical questions about targeted killings and the future of covert statecraft.
