In his remarks on Thursday, Shekarchi cautioned Washington against any “unwise actions,” saying such moves could provoke a reaction from Iran’s Armed Forces “you have never experienced before in your history.”

He emphasized that Iranian forces remain on high alert and are closely monitoring all military activity by the United States and its regional allies, including the Israeli regime.

In response to repeated threats from Trump, Shekarchi characterized the rhetoric as empty posturing and fantasy.

“The armed forces of the Islamic Republic of Iran, relying on their defensive and offensive capabilities and the support of the country's brave, united, and resilient people, are monitoring all movements of the US army and the Zionist regime in the region with great care and full readiness,” he stated.

He described the US military presence in West Asia as “psychological warfare, blackmail, and bullying.”

Shekarchi said that if US officials were “wise and rational” and fully understood Iran’s “true military capabilities,” they would refrain from discussing war.

He warned that any provocative action by American forces or affiliated groups would trigger a “decisive response and crushing blows from the Islamic Republic of Iran.”

The spokesman added that, in the event of aggression, “American soldiers and their equipment will be destroyed, and all US resources and interests in the region will be within the firing range of Iranian forces.”

“We have proven that we are not warmongers, but we are not afraid of war, and we will defend the country and the interests of the dear Iranian nation with strength,” he said.

Meanwhile, the remarks came amid rising tensions in the region. Trump has ordered additional US military deployments, including an extra aircraft carrier, thousands of troops, warplanes and guided-missile destroyers, according to US officials.

During his State of the Union address (delivered on February 24, 2026, to a joint session of Congress), Trump addressed Iran in a section roughly 90 minutes into his record-length speech. He struck a belligerent tone while expressing a preference for diplomacy, stating: "My preference is to solve this problem through diplomacy, but one thing is certain: I will never allow the world’s number one sponsor of terror, which they are by far, to have a nuclear weapon."

He accused Iran of restarting its "sinister" nuclear ambitions despite prior US strikes, reiterated that he would not permit a nuclear-armed Iran, and highlighted missile developments as a growing threat.

Trump framed this amid ongoing negotiations, noting Iran "wants to make a deal" but has not uttered the "secret words" of permanently forswearing nuclear weapons. The remarks laid out a case for potential military action if diplomacy fails, though he presented himself as favoring a deal over war. Iran dismissed these as "big lies," particularly regarding nuclear rebuilding.

Earlier this year, Trump referred to “another beautiful armada” of warships heading toward Iran and said that failure to reach a deal would lead to consequences “far worse” than the illegal strikes of June 2025 on Iranian nuclear facilities.
