Iran Will Keep Fighting Until US 'Regrets Grave Miscalculation,' Security Chief Ali Larijani Says

Iranian security chief Ali Larijani publicly vowed that Iran “will not relent” in its fight and demanded the United States come to “regret the grave miscalculation” of launching the war, posting his statement on X and directly addressing US President Donald Trump.

Larijani’s words — “We will not relent until making you sorry for this grave miscalculation” — were quoted verbatim by Middle East Eye and echoed in Vanguard News’s coverage of the remarks.

The statements frame Iran’s stance as uncompromising and aimed at reversing what Larijani called a strategic error by the United States.

The remarks come amid reporting that the conflict involving the United States and Israel against Iran has widened, disrupting global energy markets and halting traffic through the Strait of Hormuz.

Vanguard News cited AFP reporting that the war had "expanded across the Gulf and beyond," prompting the IEA’s unprecedented release of 400 million barrels of oil to stabilize markets.

That broader context in Vanguard’s coverage places Larijani’s pledge within an intensifying regional and global crisis tied to energy and shipping chokepoints.

Larijani directly rebuked President Trump’s expectation of a quick victory, saying “starting a war is easy, it cannot be won with a few tweets,” language highlighted in both Middle East Eye and Vanguard reporting.

The quote frames Tehran’s messaging as both defiant and dismissive of US political rhetoric.

Both outlets underscore that Larijani used social media (X) to issue the warning, signalling Tehran’s intent to communicate forcefully and publicly rather than through quiet diplomacy.

Available coverage in these sources is consistent in its core points — Larijani’s uncompromising statement, the public medium (X), and the linkage to a broader regional conflict — but details beyond these quotes are limited in the snippets provided.

Vanguard adds energy-market consequences and AFP photo attribution, while Middle East Eye focuses on Larijani’s direct language; neither excerpt supplies further operational details about Iran’s strategy, specific actions to follow, or independent corroboration of on-the-ground developments, leaving gaps that would require additional reporting to fill.
