Iran has issued a stark warning to the United States, pledging a “firm and immediate” response if U.S. President Donald Trump follows through on threats to bomb the country amid stalled nuclear deal negotiations.

The warning from Iran’s Foreign Ministry came after Trump vowed to strike Iran “like never before” if a new nuclear deal was not reached. The formal notice was delivered to a Swiss diplomat, who was assured the message would be conveyed to Washington. The Iranian diplomat condemned Trump’s statements, calling them provocative and a violation of international law and the UN Charter.
Earlier, Trump had set a two-month deadline in a March 7 letter to Iran’s Supreme Leader Ayatollah Ali Khamenei, urging negotiations and warning of “devastating consequences” if Tehran advanced its nuclear program. Iran rejected the proposal for direct talks, prompting Trump to reiterate his threat on NBC:
“If they don’t make a deal, there will be bombing—the likes of which they have never seen before.”
The escalating rhetoric coincided with the deployment of B-2 Spirit stealth bombers to the British island of Diego Garcia in the Indian Ocean—positioned within striking range of Iran. The bombers, capable of delivering 25-ton payloads with precision, serve as a formidable deterrent.

Ayatollah Khamenei responded defiantly, warning the U.S. against any military action:
“If they commit any mischief, they will surely receive a strong reciprocal blow.”
As he delivered the speech, crowds chanted “Death to America,” recalling the charged atmosphere of the 1980s revolution. Meanwhile, Iran has reportedly positioned missiles in fortified underground facilities, readying for potential strikes against U.S. targets.
Iranian President Masoud Pezeshkian rejected direct negotiations but left the door open to indirect talks, stating:
“We don’t avoid talks—it’s the breach of promises that has caused issues for us so far. [The U.S.] must prove that they can build trust.”
As tensions escalate, the world watches closely to see if diplomacy can avert a catastrophic conflict.
