Washington: US President Donald Trump has issued a strong warning to Iran’s top leadership, saying Supreme Leader Ayatollah Ali Khamenei “should be very worried” as Washington and Tehran prepare for renewed nuclear negotiations amid heightened military and diplomatic pressure. The remarks came during an interview with NBC News, excerpts of which were reported by CNN, and signal a sharper tone from the US even as backchannel diplomacy appears to be moving forward.
The warning comes at a time of renewed tensions between the two countries, with military posturing in the region and parallel signals that talks may soon resume to prevent further escalation over Iran’s nuclear programme.
Trump’s warning to Iran’s leadership
In the NBC News interview, President Trump was asked directly about Iran’s supreme leader and whether he had a message for him as nuclear negotiations are being lined up again. Responding bluntly, Trump said Ayatollah Ali Khamenei should be “very worried”.
“I would say he should be very worried, yeah. He should be,” Trump said, according to the reported excerpts. The statement reflects the administration’s increasingly forceful rhetoric toward Tehran, even while leaving the door open for negotiations.
Trump has repeatedly warned in recent weeks that if Iran does not agree to a nuclear deal acceptable to Washington, there could be serious consequences. He has used phrases such as “bad things could happen” if diplomatic efforts fail, combining pressure tactics with offers of talks.
Iran signals conditional readiness for talks
Even as the rhetoric has intensified, Iran has conditionally agreed to hold talks with the United States to avert the threat of further military strikes, according to CNN. The discussions are expected to focus on Iran’s nuclear activities and possible limits, monitoring mechanisms and sanctions-related issues.
Reports indicate that Oman is likely to host the negotiations. Iran’s ISNA news agency has also pointed to Oman as the probable venue for the next round of talks. Oman has historically played the role of a quiet mediator between Washington and Tehran and has hosted secret and formal discussions in earlier nuclear diplomacy phases.
Diplomatic observers say Oman’s involvement suggests that indirect channels have remained open despite public hostility between the two sides.
Military pressure and regional build-up
The diplomatic push is unfolding alongside visible military signalling by the United States. According to multiple reports, a US carrier strike group and additional military assets have been moved into the Middle East region in recent weeks. The deployments are being interpreted as a pressure lever aimed at strengthening Washington’s negotiating position.
The Trump administration’s approach appears to combine deterrence and diplomacy — raising the cost of non-cooperation while offering a path to de-escalation through talks.
Security analysts note that such dual-track strategies — coercive pressure plus negotiation — have been used before in nuclear diplomacy with Iran, though outcomes have varied depending on regional politics and internal leadership dynamics in both countries.
Iran highlights missile and deterrence upgrades
Parallel to the US warnings, Iran’s military leadership has highlighted upgrades to its domestic missile capabilities and a shift in strategic doctrine. Iranian state broadcaster Press TV reported that Chief of Staff of the Iranian Armed Forces Abdolrahim Mousavi visited a missile facility operated by the Islamic Revolution Guards Corps (IRGC).
During the visit, Mousavi said Iran has strengthened its deterrence power by upgrading domestically produced ballistic missile systems across technical dimensions. He said the enhancements improve performance and readiness.
He also stated that after a recent 12-day conflict period referenced by Iranian media, the country has adjusted its military doctrine from a largely defensive posture to a more offensive, asymmetric warfare-oriented approach. According to the report, he spoke of readiness for a “crushing response” to hostile actions.
The comments are being seen as a counter-signal to US and allied military movements, aimed at reinforcing Iran’s deterrence narrative ahead of negotiations.
Diplomatic window amid mutual distrust
Despite sharp language on both sides, the indication that talks may resume suggests that neither Washington nor Tehran wants immediate military confrontation. However, mutual distrust remains high, and past negotiations have often stalled over verification standards, sanctions relief sequencing and enrichment limits.
Experts say the success of any upcoming round of talks will depend on whether both sides are willing to accept phased commitments and credible monitoring frameworks. Domestic political pressures in both countries could also shape the flexibility of negotiators.
Conclusion
President Trump’s warning that Iran’s supreme leader “should be very worried” underscores the tense backdrop against which fresh nuclear talks may take place. With military pressure rising and diplomatic channels reopening through Oman, the coming weeks could prove critical in determining whether the US and Iran move toward de-escalation or slide into deeper confrontation. The balance between deterrence and dialogue will likely define the next phase of this long-running nuclear standoff.
