Why Tehran May Be Preparing to Leave the Non-Proliferation Treaty
As U.S. and Israeli warplanes continue to strike Iranian nuclear and military infrastructure, a quieter but potentially more consequential development is unfolding in Tehran: the Islamic Republic may be preparing to withdraw from the Treaty on the Non-Proliferation of Nuclear Weapons.
Iranian media reported Monday that relevant institutes, including the parliament, are actively considering withdrawal from the NPT, with the semi-official Tasnim news agency noting that “the conclusion that there is no reason for Iran’s remaining in the NPT is becoming certain in the country”.
If Iran follows through, it would be only the second country in history to withdraw from the treaty after North Korea—and the geopolitical consequences would be seismic. An Iran free of NPT constraints could resume uranium enrichment at levels far beyond those required for civilian power generation, potentially racing toward a nuclear weapon in a matter of months rather than years.
The timing of the NPT debate is not coincidental. Israeli and U.S. strikes have already done “severe damage” to Iran’s heavy water production plant in Khondab, according to the IAEA. The facility is “no longer operational,” effectively crippling one leg of Iran’s nuclear program. With its infrastructure in ruins and its leadership under unprecedented military pressure, Tehran may calculate that it has nothing left to lose by abandoning the treaty entirely.
U.S. officials are aware of the risk. Secretary of State Marco Rubio said Monday that there are “fractures” inside Iran’s leadership, and that Washington is receiving messages from Iranian figures “in ways that previous people in charge have not spoken to us in the past”. But it remains unclear whether those fractures represent an opportunity for diplomacy or a prelude to collapse.
Iran’s parliament speaker, Mohammad Bagher Qalibaf, has already warned that any ground attack on Iran would face a “decisive response”. The regime is signaling that it is prepared for a long war—and that it may be willing to cross nuclear thresholds that have been unthinkable for decades.
For the international community, the prospect of a nuclear-armed Iran—or, perhaps worse, a failed state with nuclear materials scattered across a war zone—represents a nightmare scenario. But with global attention focused on oil prices and battlefield gains, the slow-motion collapse of the non-proliferation regime is unfolding largely unnoticed.
