UN Nuclear Chief: Iran Has Bomb-Making Material — But No Active Weapons Program

As tensions escalate between Israel and Iran, and with former President Donald Trump reportedly weighing U.S. involvement, the world’s top nuclear watchdog says there’s no evidence Iran is racing to build a nuclear bomb.

In an interview with Fox News, Rafael Grossi, Director General of the International Atomic Energy Agency (IAEA), confirmed that while Iran currently possesses enough fissile material to build several nuclear warheads, there’s no sign that the country is actively working to make them.

“We have confirmed that Iran does have, even now, enough material for several warheads,” Grossi said.
“But this should not be equated with a nuclear weapon. We do not have at this point… any tangible proof that there is a program, or a plan, to fabricate… a nuclear weapon.”

Inspections Interrupted, but Satellite Eyes Still Watching

Grossi’s agency, which operates under the United Nations, is responsible for monitoring nuclear programs worldwide — including Iran’s. However, IAEA inspectors haven’t been able to access Iranian sites since Israel launched a new round of military strikes earlier this month. The agency is now relying on satellite surveillance to track developments.

When asked if the Israeli strikes had dealt a significant blow to Iran’s nuclear capabilities, Grossi was blunt: “No, I wouldn’t say so.”

“There have been a number of important military attacks,” he acknowledged. “But it is very clear… not everything has been taken out.”

Bombing Can’t Erase Knowledge

One of Grossi’s key messages: Military action can destroy facilities, but not erase decades of scientific progress.

“There is the knowledge factor,” he said. “It is very difficult to roll back the knowledge that a country has acquired.”

That’s especially relevant as Israel continues targeting Iranian nuclear scientists — attacks Tehran has publicly blamed on Israel. Several top scientists have been killed in recent days, adding to a long history of covert operations aimed at stalling Iran’s nuclear program.

Diplomacy Still on the Table — But the Window Is Closing

Despite the current violence, Grossi remains hopeful that diplomacy can still work. He emphasized that a negotiated deal to prevent Iran from developing nuclear weapons is both possible and preferable.

“I believe that there is a way to take this danger — or this concern — off the table in a negotiated way,” he said.

Grossi noted that he’s held “very good conversations” with both Iranian officials and Trump’s envoy, Steve Witkoff.

“We believe there are ways to make sure Iran does not get a nuclear weapon. I think this is what Israel wants, and what the U.S. has declared.”

But he warned that time is running out.

“We believe that the opportunity should be seized — as President Trump said — but of course, the space for that is narrowing.”

The Bottom Line

Iran may have the raw materials for nuclear weapons, but according to the UN’s top nuclear official, it has no current plan or active program to build them.
With inspections disrupted, regional violence growing, and the political window for diplomacy shrinking, the stakes are rising fast — and the world is watching to see whether leaders choose confrontation or negotiation.
