Khamenei Defends Iran's Nuclear Activity
Iran’s Supreme Leader, Ayatollah Ali Khamenei, publicly rejected U.S. opposition to Iran’s uranium enrichment activities, asserting that Western powers cannot dictate Iran’s nuclear policies.
Khamenei’s comments were made during a high-profile meeting with nuclear industry officials and scientists in Tehran.
The statement comes at a time when international scrutiny over Iran’s nuclear program has intensified, especially following reports by the International Atomic Energy Agency (IAEA) regarding the presence of highly enriched uranium.
“We were told not to enrich above 3.67%, but look where we are now,” Khamenei said, referencing Iran’s progression to 60% enrichment, which is closer to weapons-grade uranium levels.
Context: Iran and the Nuclear Deal
In 2015, Iran signed the Joint Comprehensive Plan of Action (JCPOA) with world powers, agreeing to limit its uranium enrichment in exchange for relief from international sanctions. However, the United States withdrew from the deal under former President Donald Trump in 2018 and reimposed sanctions.
Since then, Iran has gradually scaled back its compliance with the JCPOA, enriching uranium at higher levels and installing advanced centrifuges. Talks to revive the agreement have stalled for over a year.
IAEA’s Latest Concerns
The IAEA reported earlier in May 2025 that traces of uranium enriched up to 83.7%—just below the 90% typically required for nuclear weapons—had been detected in Iran. While the agency said the findings might be the result of unintentional accumulation during technical testing, it reignited global concerns.
The report also noted that Iran currently possesses enough 60% enriched uranium that, if further enriched, could be used to manufacture multiple nuclear weapons. The IAEA Board of Governors is expected to convene soon to consider a formal resolution against Iran.
Iran’s Position on Enrichment
Khamenei’s remarks reinforced Iran’s position that it would continue enrichment for peaceful purposes, including medical and energy-related uses. He insisted that Iran had no intention to build nuclear weapons but emphasized the country's right to scientific advancement.
Iran also continues to deny access to certain nuclear sites and has limited cooperation with IAEA inspections since February 2021. Khamenei reiterated his distrust in the West and defended Iran’s move to decrease transparency, claiming Western powers “weaponize” oversight to pressure Tehran.
U.S. and European Response
The United States, along with European allies, has repeatedly urged Iran to return to the terms of the JCPOA and limit its uranium enrichment activities. Officials in Washington have called on Iran to increase transparency with the IAEA and resume full cooperation.
In response to the latest developments, a U.S. State Department spokesperson stated that Iran’s accumulation of highly enriched uranium is "deeply concerning" and not consistent with a peaceful nuclear program.
No Immediate Diplomacy on Horizon
Diplomatic channels between Tehran and Washington remain mostly closed. Although backchannel talks via intermediaries like Oman and Qatar have occurred in recent months, no substantial breakthroughs have been reported. Iran’s hardline stance, as expressed by Khamenei, signals continued resistance to Western pressure and a belief that Iran can pursue nuclear advancement on its own terms.
Summary of Key Developments
Iran’s Supreme Leader rejects U.S. opposition to high-level uranium enrichment.
Iran currently enriches uranium to 60% and has enough material that could be further refined for weaponization.
The IAEA detected traces of uranium enriched to nearly weapons-grade levels.
Khamenei reaffirmed Iran’s right to nuclear research and rejected Western oversight demands.
Efforts to revive the 2015 nuclear deal remain stalled, with no diplomatic progress expected soon.
