Analysis of Iranian Supreme Leader's Statements on The Country's Nuclear Program Progress
The Iranian Supreme Leader stated that Tehran has limited enrichment to 60 percent purity, contrasting this with the 90 percent level required for weapons-grade uranium
MIDDLE EAST — On September 23, 2025, Iran’s Supreme Leader Ayatollah Ali Khamenei addressed the nation’s uranium enrichment program, emphasizing its civilian applications and denying any intent to develop nuclear weapons. He stated that Iran has limited enrichment to 60 percent purity, contrasting this with the 90 percent level required for weapons-grade uranium.
The IAEA has confirmed Iran’s enrichment to 60 percent purity, stating that this level lacks a credible peaceful justification. Assessments reveal ongoing restrictions on inspector access since 2023, including the de-designation of experienced personnel.
Khamenei’s address outlined the roles of enrichment in sectors such as agriculture, the environment, electrical energy, medicine, and various industries.
Documents from the IAEA indicate that while 60 percent enrichment can support research reactors, the accumulated stockpiles pose significant proliferation risks. Between 14 and 16 countries possess uranium enrichment capabilities, encompassing non-weapons states such as Japan and Germany.
In his speech, Iran’s Supreme Leader underscored Iran’s resistance to external pressures, particularly viewing negotiations with the United States as counterproductive. The comments firmly dismissed direct talks with the U.S., portraying them as detrimental when conducted under threats.
Positions from the United States insist on halting enrichment activities, a demand that Iran consistently opposes. Iran’s approach has remained resolute in the face of international pressure, maintaining that its enrichment is for peaceful purposes, despite enriching to weapons-grade levels not necessary for peaceful applications.
