Iran Warns US About Direct Involvement

As the United States shifts fighter jets and an aircraft carrier to the Middle East, “postured defensively in the region to be strong, in pursuit of a peace deal,” according to Defense Secretary Pete Hegseth, Iran is sending a warning about direct U.S. involvement in its conflict with Israel.

In an interview with Al Jazeera, Foreign Ministry spokesman Esmail Beghaei said “any American intervention would be a recipe for an all-out war in the region.”

Iran's Supreme Leader Ali Khamenei also weighed in Wednesday morning.

The US entering in this matter [war] is 100% to its own detriment. The damage it will suffer will be far greater than any harm that Iran may encounter.

The US President threatens us. With his absurd rhetoric, he demands that the Iranian people surrender to him.
They should make threats against those who are afraid of being threatened. The Iranian nation isn’t frightened by such threats.

The harm the US will suffer will definitely be irreparable if they enter this conflict militarily.

The Middle East Media Research Institute also documented other threats from the nation.

Iranian Majles Member Mahmoud Nabavian said on Channel 3 (Iran) on June 16, 2025, that countries in the region - including Israel and the United States - should be warned that if they attempt to block Iran’s oil exports or disrupt domestic supply, no other country will be able to export or access oil for domestic use either. “They should take my threat seriously,” he warned.
Nabavian said that Iranian missiles could reach American bases in the region within 2–4 minutes, making them impossible to intercept, and added that striking an American destroyer is well within Iran’s capabilities. He said Iran is monitoring Diego Garcia and has plans for it.
He warned the U.S. that before even contemplating aggression against Iran, it should prepare 50,000 coffins for its troops, “before they even dare take a hostile glance at the Iranian nation.” He also said Iran would retaliate against Israel for the assassination of its Chief of Staff with assassinations of its own, whether during or after the war.

The threats come after President Trump called for Iran's “unconditional surrender” and warned Iran's supreme leader "we" know where he’s hiding.

"We know exactly where the so-called 'Supreme Leader' is hiding," Trump said on Truth Social. "He is an easy target, but is safe there - We are not going to take him out (kill!), at least not for now. But we don’t want missiles shot at civilians, or American soldiers. Our patience is wearing thin. Thank you for your attention to this matter!"
