Trump Says US Could 'Blow Up' Iran as Hegseth Claims Military Devastation

President Donald Trump escalated his rhetoric toward Tehran on Wednesday, telling reporters that Washington faces a binary choice in its confrontation with Iran: either secure a negotiated deal or resort to overwhelming military force. Speaking during an event marking Hispanic Heritage Month, the US president said the country could "blow them up" if diplomacy fails, according to Al Jazeera's live coverage of the unfolding crisis.

Trump's remarks, delivered in the Oval Office, represent his most explicit public threat of direct military action against Iran in recent weeks. He also repeated his assertion that the United States maintains "virtually total control" over the Strait of Hormuz, the narrow waterway through which roughly a fifth of the world's oil supply passes. The strategic chokepoint has been a central flashpoint in the ongoing US-Israel campaign against Iran.

The president's comments came as he warned that time was running short for Tehran to reach an agreement with Washington. His phrasing suggested a growing impatience with the diplomatic track, even as he left the door open to a negotiated settlement. The dual message—deal or destruction—echoed earlier ultimatums issued during the conflict, but carried added weight given the recent tempo of military operations.

Earlier in the day, US Defence Secretary Pete Hegseth delivered a stark assessment of the campaign's progress to military leaders gathered at the Quantico Marine base outside Washington, DC. Hegseth claimed that American forces have "destroyed" Iran's navy, air force, defence systems, leadership, and military-industrial capacity. He further asserted that the strikes had crippled Iran's nuclear ambitions.

The defence secretary's remarks, if accurate, would represent a near-total dismantling of Iran's conventional military infrastructure. Such claims, however, are difficult to independently verify in the midst of an active conflict, and Iranian officials have consistently disputed US assessments of battlefield damage. The disparity between American and Iranian accounts has been a recurring feature of the war's information landscape.

Hegseth's speech at Quantico, a major Marine Corps installation in Virginia, appeared designed to project confidence in the campaign's trajectory. By listing specific categories of Iranian military capability—naval, aerial, defensive, leadership, and industrial—he sought to convey a comprehensive degradation of Tehran's ability to project power or defend its territory. The inclusion of "leadership" in that list hinted at the possibility that senior Iranian command figures have been killed or incapacitated.

The nuclear dimension remains perhaps the most consequential element of Hegseth's claims. If US operations have genuinely set back Iran's nuclear programme, that would mark a significant strategic achievement from Washington's perspective. Iran has long insisted its nuclear activities are peaceful, though Western powers have accused it of pursuing weapons capability. The war has added urgency to those longstanding tensions.

Trump's Strait of Hormuz comments are particularly significant given the waterway's role in global energy markets. The strait connects the Persian Gulf to the Gulf of Oman and serves as the primary export route for Saudi Arabia, Iraq, Kuwait, Qatar, and the United Arab Emirates, as well as Iran itself. Any disruption there would send shockwaves through oil prices and the broader global economy.

The claim of "virtually total control" over the strait suggests that US naval and air forces have established dominance over the approaches to the waterway. Control of such a critical maritime artery would give Washington enormous leverage over Tehran's economic lifeline while also reassuring Gulf allies concerned about Iranian retaliation. It is a claim that, if substantiated, would reshape the strategic balance in the region.

The live coverage, published on 1 October 2026, forms part of Al Jazeera's ongoing reporting on the US-Israel war on Iran. The conflict has generated a series of flashpoints, including earlier questions about strikes resuming and speculation about whether Iran had captured an unmanned US submarine. The network's live blog has tracked these developments as they unfold.

Trump's Hispanic Heritage Month event provided an unusual venue for such hawkish remarks, underscoring how the Iran conflict has permeated nearly every aspect of American public life. The president has used a variety of settings—from formal briefings to cultural celebrations—to telegraph his intentions toward Tehran. This pattern reflects his preference for projecting strength across multiple audiences simultaneously.

The choice-or-consequence framing Trump employed—deal or destruction—leaves little room for ambiguity. It places the onus squarely on Iranian leaders to decide whether to negotiate terms acceptable to Washington or face further military consequences. Such ultimatums can serve as diplomatic pressure tactics, but they also risk cornering an adversary into a position where resistance becomes a matter of national survival.

For Iran, the combination of Hegseth's damage assessment and Trump's threats presents a grim strategic picture, at least as characterised by American officials. If the US claims are accurate, Tehran faces a severely degraded military apparatus and eroding options for retaliation. Yet the regime has shown resilience in the past, and asymmetrical responses—through proxies, cyber operations, or maritime harassment—remain possible.

The broader regional implications extend beyond Iran's borders. Israel, which has been a central participant in the campaign, would benefit from any lasting reduction in Iranian military capability. Gulf Arab states, meanwhile, are caught between their hostility toward Tehran and their nervousness about a wider war that could disrupt oil exports and draw in their own populations.

International observers will be watching closely for any response from Tehran, whether diplomatic or military. Previous cycles of escalation have seen Iran issue defiant statements while calibrating its actual retaliation to avoid provoking a catastrophic US response. Whether that pattern holds—or whether the latest threats push the region into a new and more dangerous phase—remains the central question.

Trump's remarks also carry domestic political implications. By publicly threatening to "blow up" Iran, he signals to his base that he remains willing to use force decisively. At the same time, the insistence that a deal remains possible provides political cover for those who prefer diplomacy. This dual messaging allows the administration to claim credit whether the conflict ends in negotiations or on the battlefield.

As the war continues, the gap between American confidence and Iranian defiance will define the next phase of the crisis. Hegseth's assertions of total military dominance and Trump's warnings about time running out suggest that Washington believes it holds the upper hand. Tehran's next move—whether toward the negotiating table or toward further confrontation—may determine whether the coming weeks bring de-escalation or a new round of strikes.
