Unresolved talks over Iran's nuclear activities and passage through the Strait of Hormuz form the backdrop against which the Pentagon has reportedly been weighing options that include deploying its largest conventional munition. Hostilities between Iran and neighbouring states have broadened into a multi-front confrontation, with Iranian forces reported to have struck energy infrastructure and carried out repeated attacks on commercial vessels navigating the Strait of Hormuz — a chokepoint through which an estimated one-fifth of global oil supplies passes.
Negotiators have not managed to reach a durable agreement across multiple rounds of talks over recent months, leaving administration officials to weigh their options on how to bring the fighting to a close. On Thursday, a television news outlet disclosed that the armed forces had drawn up updated attack options, among them the possibility of deploying a 21,600-pound conventional bomb — the heaviest non-nuclear munition held in the country's stockpile. Prior to the conflict's outbreak in February, the weapon had gone without deployment against Iran, and its last recorded use anywhere dated back to 2017.
Reports indicate that administration officials have been examining the possibility of expanding military action to cover both Iranian energy infrastructure and nuclear installations, among them the site known as Pickaxe Mountain. The munition's design centres on wide-area surface dispersal, a configuration that leaves it without the penetrating depth required to reach fortified subterranean sites — the kind targeted in past operations against Iranian nuclear infrastructure.
One option under review at the Pentagon — among several being weighed for President Donald Trump — involves deploying the weapon, a move that would deepen involvement in a conflict now entering its eighth month and extending across the broader region. Whether further pressure would produce a different outcome remains an open question, given that a prolonged combination of military action, economic measures, and diplomatic engagement has so far left Iran's stated positions unchanged.
Bombing raids, trade restrictions, a blockade of the Strait of Hormuz, and the deaths of several senior figures have not moved Iran toward the conditions put forward by Washington, with Iranian officials stating their intention to continue the conflict. Negotiations over Iran's nuclear programme have broken down across multiple rounds, with the two sides unable to bridge their differences over what path forward should look like.
Competing claims over navigation rights through the Strait of Hormuz have placed Iran at odds with the United States and its partner nations, each side holding a different view of who governs the waterway. Talks aimed at resolving the standoff have stalled over the past several weeks, with neither party moving toward an agreement and both readying for a potential upturn in hostilities.
Certain analysts viewed the prospect of intensified airstrikes as a pressure tactic aimed at drawing Iran's leadership back to diplomatic talks, particularly given that the deaths of several moderate figures have left the government with a more hardline orientation. Mark Chandler, a former head of the Defense Intelligence Agency's Middle East and Africa Center who now teaches at Coastal Carolina University, described the maneuver as a form of strategic communication intended to demonstrate military capacity, while adding that genuine negotiation was unlikely to follow without actual force being applied.
That assessment gained context when a senior Iranian official, in a televised address on Wednesday, called on the country to prepare for armed conflict even while pursuing diplomacy. Protection measures at installations considered militarily and energetically sensitive have been stepped up, according to reports, as talk of resumed airstrikes — activity that has largely been in abeyance — has grown more pronounced.
Pressure on Trump to bring the fighting to a close has been building, while petrol prices at the forecourt point to the strain the conflict has placed on oil supply. The president indicated the conflict would conclude in short order, while also stating that military operations were set to resume following the Nov. 3 midterm elections, adding in a public address that oil prices would fall and the opposing party would not obtain nuclear weapons.
During a television interview conducted while he was out on the campaign trail that Wednesday, Trump described the dispute as having always been rooted in nuclear weapons, and stated that the opposing party would not be allowed to acquire one. Speaking at the rally, Trump told the crowd he was uncertain which Iranian counterparts remained available for any potential negotiations, given that dozens of the country's leadership figures had died in the opening phase of the conflict, adding that Iran's naval forces no longer existed. He further stated that no aerial combat capability exists within their military inventory and that the force has taken considerable losses.
The president noted that opposing leadership had been eliminated, then questioned the utility of that outcome given the uncertainty about who now holds negotiating authority on the other side. A separate line of scrutiny has focused on whether pausing the air campaign against Iran — both during a brief ceasefire period over the summer and again ahead of the midterm elections — gave Tehran room to recover without resolving the root tensions driving the conflict. Chandler contended that the pauses reflected incomplete follow-through, arguing that whatever reasoning led the administration to stand down at those junctures — whether a belief that Iran would come to the table or some other calculation — left the task unfinished in a way that has since allowed Iran to rebuild and restore the capabilities that had been degraded.
