President Donald Trump announced on Monday that the United States, in collaboration with Israel, has already dismantled Iran’s nuclear program. He further warned that Tehran would face military repercussions if it attempted to rebuild its capabilities. This statement comes amidst emerging reports suggesting that Iran is actively seeking to enhance its ballistic missiles with chemical and biological warheads.

While speaking at Mar-a-Lago with Israeli Prime Minister Benjamin Netanyahu by his side, Trump delivered a stern message regarding Iran’s nuclear and missile efforts.

“I’ve heard rumors that Iran is attempting to revive its program, and if that’s the case, we are prepared to take decisive action,” Trump declared. “We’ll ensure they are stopped.” He emphasized that Iran would be wise to consider negotiating a deal instead.

Trump portrayed the defeat of Iran’s ambitions as critical to maintaining regional stability, asserting that coordinated military efforts by the U.S. and Israel have significantly shifted the power dynamics in the Middle East.

“We just won a big war together,” he said. “If we didn’t beat Iran, you wouldn’t have had peace in the Middle East. We wiped it out.”

Pressed on whether he would support further Israeli military action if Iran continues advancing its missile or nuclear programs, Trump responded affirmatively. “If they continue with the missiles — yes,” he said. “The nuclear — absolutely.”

The Trump-Netanyahu meeting came as Iran’s currency has hit record lows, and shopkeepers in Tehran have staged strikes over soaring inflation and a collapsing economy.

Asked whether he would support the overthrow of Iran’s regime, Trump rejected the idea while pointing to unrest inside the country.

“I’m not going to talk about overthrow of a regime,” he said. “But they have tremendous inflation. Their economy is busted.” Trump added that protests are frequently met with lethal force by Iranian authorities.

The remarks followed a report Sunday by Iran International alleging that Iran’s Islamic Revolutionary Guard Corps is accelerating work on unconventional missile payloads, including chemical and biological options, citing unnamed military and security sources.

Iran denies pursuing chemical or biological weapons and maintains its missile program is defensive. Tehran ratified the Chemical Weapons Convention in 1997 and analysts say the reported developments fit a broader pattern.

“The fact that Tehran’s ballistic missiles can carry unconventional payloads is not new,” said Behnam Ben Taleblu, a senior fellow at the Foundation for Defense of Democracies.

Taleblu pointed to Iran’s recent military behavior.  “What should underscore the chemical threat was Tehran’s use of warheads with cluster munitions against Israel during the 12-day war,” he said. “These warheads can easily carry canisters for poison gas. In short, the conflict contained a dry run for a potential chemical attack.”

He added that Iran’s history heightens concern, citing Tehran’s past use of chemical agents during the Iran-Iraq War in the 1980s and its transfer of such weapons to Libya.

Later in the day, in a press conference after the meeting with Netanyahu, Trump repeated his threats to Iran, warning the United States would move swiftly if Tehran is attempting to rebuild its weapons programs.

“Speaking of Iran, I hope they’re not trying to build up again, because if they are, we’re going to have no choice but very quickly to eradicate that build up,” Trump said. He added that he has been reading reports that Iran is “building up weapons and other things,” possibly at “different sites” than those the U.S. previously “obliterated.”

Pressed by reporters about the risk of another conflict with Iran, Trump said the information “hasn’t been confirmed,” but warned that “consequences will be very powerful,” potentially “more powerful than the last time,” if the reports prove accurate. He also said he was hearing Iran was “not nuclear yet,” but “looking at other sites,” cautioning that if Tehran is doing so, “they’re making a big mistake.”

Trump also said he would support direct talks with Tehran, noting he had backed negotiations even before the war. “I support that,” Trump said. “Before the war, I said, let’s negotiate.”

Analysts said Trump’s remarks mark a significant shift in U.S. posture toward Iran’s missile capabilities. Taleblu said Trump’s statements go beyond rhetoric. “Trump has just done what no president ever promised, to deal directly and militarily with Iran’s ballistic missile program in support of Israel,” Taleblu said. “This is historic.”

He added that Iran’s missile threat extends well beyond Israel. “Iran’s ballistic missiles have been used not just against Israel, but U.S. forces and U.S. bases in the region as well, both direct and by proxy.” Taleblu concluded, “A commitment to countering this threat is priority number one for building a better and safer Middle East.”
