What the US Military Could Do If Iran Fails to Meet Trump’s Ultimatum

The ultimatum issued by Trump threatens severe destruction of Iran’s civilian infrastructure unless a deal is reached by a tight deadline. Military analysts caution that the scale of the threat exceeds the realistic capabilities of the US military, especially when the demand calls for the rapid elimination of countless targets across a nation the size of Iran.

Trump has publicly declared an intention to dismantle “every bridge” and every power station in Iran within a matter of hours if the stipulated deadline passes. The rhetoric escalated further with a declaration that an entire civilization could perish without compliance. Such a proclamation represents an unprecedented level of direct threat from a sitting US president toward a sovereign state’s civilian population.

Critics argue that targeting civilian infrastructure would constitute a violation of international humanitarian law, classifying the act as a potential war crime. Trump dismissed these concerns during a press briefing, stating that legal interpretations would not affect the pursuit of the stated objectives.

Feasibility of the Threat

Former senior US defence officials and independent analysts aGree that the logistical and operational challenges of carrying out the exact threat are virtually insurmountable. Iran spans roughly one‑third the land area of the continental United States, encompassing a vast network of bridges, highways, power stations, and ancillary facilities. While US intelligence possesses precise coordinates for Iran’s major nuclear sites and other high‑value installations, pinpointing and neutralising the multitude of smaller, yet critical, civilian structures in a compressed timeframe presents a herculean undertaking.

“To meet this threat literally would be an absolute herculean task. And would it have the desired strategic effect?” a former senior US defence official, who requested anonymity, remarked. “Trump is almost struggling to come up with a new level of threat that he can say with words that will move the strategic needle more in favour of the US here.”

The United States would need to mobilise an unprecedented number of precision‑guided munitions, coordinate simultaneous strikes across three distinct coastal provinces, and overcome the challenges of targeting in densely populated urban environments—all while avoiding collateral damage that could trigger broader humanitarian condemnation.

Given these constraints, a large‑scale assault on Iran’s power sector emerges as a more attainable approach than the elimination of every bridge. The majority of Iran’s power generation facilities and oil refineries are concentrated in three coastal provinces: Bushehr, Khuzestan, and Hormozgan. Targeting power plants within this corridor could inflict a substantial blow to the Iranian economy and limit the regime’s ability to finance its war effort.

Miad Maleki, a former senior US treasury official who oversaw sanctions against Iran, explained that striking these three provinces would simultaneously disrupt oil revenues, cripple access to the Persian Gulf, and hamper traffic through the strategic Strait of Hormuz. “You do anything to those three provinces, you cut the regime’s access to oil revenue and its access to the Persian Gulf and Strait of Hormuz,” Miad Maleki, senior fellow at the Foundation for Defense of Democracy, said.

Political and Diplomatic Context

Vice‑President JD Vance announced that US airstrikes have already been conducted against military targets on Kharg Island, a key node handling roughly ninety percent of Iran’s oil exports. JD Vance clarified that these strikes do not signify a shift in Trump’s overarching strategy. Negotiations with Iran will continue up to the deadline, but the United States retains the option to apply “much greater pain” to Iran’s economy if Tehran does not alter its conduct.

“So they’ve got to know, we’ve got tools in our toolkit that we so far haven’t decided to use. The President of the United States can decide to use them, and he will decide to use them, if the Iranians don’t change their course of conduct,” JD Vance told reporters in Budapest.

The White House dismissed any speculation that JD Vance’s remarks hinted at a US nuclear strike against Iran. Nevertheless, reports indicate that some civilian infrastructure has already been hit. Iran’s state media claimed that US‑Israeli airstrikes targeted a bridge in the city of Qom, while Trump previously asserted that the United States bombed Iran’s largest bridge.

Direct communications between US and Iranian officials have reportedly taken place after indirect talks stalled. Both sides remain entrenched on core issues, including the future of Iran’s oil sector, the trajectory of its nuclear program, and control over the Strait of Hormuz.

Trump announced that his special envoy Steve Witkoff, son‑in‑law Jared Kushner, and JD Vance are leading the diplomatic effort. A US official, speaking on condition of anonymity, clarified that Steve Witkoff and Jared Kushner manage day‑to‑day negotiations, while JD Vance would become more directly involved only if progress reaches a critical threshold.

“The Vice‑President may be tagged in more directly if there’s sufficient progress made by Steve Witkoff and Jared Kushner,” the official said.

Trump may be counting on internal pressure within Iran to force the regime to negotiate if a widespread blackout were to occur. However, Miad Maleki noted that Iranian citizens already endure frequent power outages, and additional blackouts are unlikely to serve as a decisive bargaining chip.

“This is not a wartime issue,” Miad Maleki stated. “The Iranian people are already dealing with a completely dysfunctional energy and power sector.”

Strategic Implications of Targeting Power Infrastructure

Attacking Iran’s power grid could complicate Trump’s broader goal of reopening the Strait of Hormuz. Iran has effectively halted most oil tanker traffic through the waterway, destabilising global oil markets and driving prices upward. A severe degradation of Iran’s power capacity might reduce its ability to sustain maritime operations, yet it could also provoke further retaliation, potentially widening the conflict.

Jason Campbell, a former Department of Defense official who served under both the Biden and Trump administrations, argued that Trump has not presented a compelling case that escalation will achieve US objectives. “Nearly six weeks into the war, the Iranian regime has shown it has a high pain threshold and won’t easily cave to US demands,” Jason Campbell, senior fellow at the Middle East Institute, observed.

For Iran’s leadership, the conflict represents an existential struggle that extends beyond territorial concerns to the survival of the governing regime itself. “The war is an existential fight not just for the country but for the regime,” Jason Campbell added.

Given the entrenched positions on both sides, the prospect of a swift resolution appears remote. Even if the United States were able to execute a massive, coordinated strike on power facilities, the long‑term effectiveness of such an operation in compelling Tehran to negotiate remains uncertain. The Iranian leadership is likely to assess any damage within the broader context of national resilience, historical resistance to external pressure, and the regime’s capacity to rally domestic support.

Concluding Assessment

Trump’s ultimatum hinges on a dramatized threat that stretches the practical limits of US military capability. While a targeted campaign against Iran’s energy infrastructure is within the realm of possibility, the complete eradication of bridges and power stations across an entire nation within a few hours is virtually unattainable.

The diplomatic landscape reflects deep divisions on vital issues, and the United States appears to be leveraging both coercive measures and high‑level negotiations simultaneously. Analysts caution that any escalation must be weighed against the potential for broader regional destabilisation, humanitarian fallout, and the legal ramifications of targeting civilian infrastructure.

Ultimately, the path forward will be shaped by a complex interplay of military feasibility, diplomatic resolve, and the willingness of both Washington and Tehran to endure the costs of an extended confrontation. The outcome will depend on whether Trump’s threats translate into actionable force, how Iran’s leadership perceives the credibility of those threats, and the extent to which external actors—particularly regional powers and global markets—can influence the trajectory of the conflict.
