Iran could enrich uranium to 90% purity if it comes under attack again, a senior Iranian lawmaker said on Tuesday, underscoring how quickly the nuclear issue could return to the center of a renewed confrontation with the United States and Israel.
Ebrahim Rezaei, spokesperson for the Iranian parliament’s National Security and Foreign Policy Commission, stated that such a step could be considered in parliament if hostilities resume. His remarks came as President Donald Trump reiterated that one of the central aims of launching the war against Iran was to ensure Tehran does not develop a nuclear weapon.
Iran, which maintains that its nuclear program is peaceful, is reportedly holding more than 400 kilograms of uranium enriched to 60%. This is described as a short technical step from the 90% level associated with weapons‑grade material. In a post on X, Rezaei said 90% enrichment could become one of Iran’s options in the event of another attack.
The warning reflects the broader strategic dispute over how the war will conclude and what conditions might prevent a new round of fighting. Israeli Prime Minister Benjamin Netanyahu has said the war will continue as long as Iran retains highly enriched uranium, arguing that both the stockpile and the enrichment facilities must be removed or dismantled.
Taken together, the remarks suggest that Tehran is signaling both capability and deterrence rather than announcing an immediate policy shift. The language appears intended to warn Washington and Israel that any renewed military action could trigger a sharper nuclear escalation.
At the same time, the statement serves a political purpose by raising the cost of further pressure and reinforcing Iran’s leverage at a moment when the ceasefire appears fragile. In that sense, the latest warning reads less like a formal declaration of weaponization and more like carefully calibrated coercive messaging rooted in Iran’s current enrichment posture.
