America Unreliable: The Collapse of U.S. Credibility Under Trump Administration

On the evening of June 21, 2025, the United States launched Operation Midnight Hammer, striking three Iranian nuclear facilities: Fordow, Natanz, and Isfahan. The attack involved B-2 Spirit stealth bombers carrying GBU-57 bunker-buster munitions, alongside Tomahawk cruise missiles fired from a submarine. U.S. officials described the operation as “very narrowly tailored,” designed to “destroy or severely degrade Iran’s nuclear program” and force Tehran back toward negotiations.

That same night, President Donald Trump declared from the White House that “Iran’s key nuclear enrichment facilities have been completely and totally obliterated.” He called the strikes a “spectacular military success.” Defense Secretary Pete Hegseth reinforced the message from the Pentagon. “Based on everything we have seen — and I’ve seen it all — our bombing campaign obliterated Iran’s ability to create nuclear weapons,” he said. Days later, on June 25, Hegseth repeated the formulation: “Iran’s nuclear program is obliterated.”

Eight months of repetition

The word was not incidental. It became the organizing claim of the administration’s public narrative. The operation, Americans were told, had not merely damaged Iran’s nuclear infrastructure; it had erased the strategic threat.

Over the following eight months, Trump repeatedly returned to this claim. Between June 2025 and February 2026, he invoked the idea of “obliteration” in numerous public remarks and statements. At different moments, he said Iran’s nuclear “capacity,” “capability,” “future capability,” “potential capability,” “hopes,” “threat,” and “enrichment capability” had been destroyed or eliminated.  As recently as February 13, 2026, he described the June strikes as “achieving total obliteration of the Iran nuclear potential capability — totally obliterated.”

The repetition mattered because it created a standard against which the administration’s later conduct would be judged. If Iran’s nuclear program had been obliterated, the threat had been removed. If the threat persisted, the claim had been false. The administration tried to occupy both positions at once.

On February 28, 2026, the United States launched Operation Epic Fury, a far larger military campaign against Iran. In announcing the new operation, Trump repeated that the U.S. military had “obliterated” Iran’s nuclear facilities the previous June. In the same breath, he said Iran had been “starting it all over.” The contradiction was obvious: a program that had been completely destroyed was now being presented as a rapidly reconstituted danger requiring another major war.

No senior official made a serious attempt to reconcile the two claims. Instead, the administration treated them as interchangeable tools. When the purpose was to celebrate past military success, Iran’s nuclear program had been obliterated. When the purpose was to justify a new campaign, the same program was once again on the verge of becoming an intolerable threat.

In his State of the Union address shortly before the February strikes, Trump said Tehran had been “warned to make no future attempts to rebuild” its nuclear weapons program, yet was doing exactly that. Trump envoy Steve Witkoff appeared on Fox News and claimed that Iran was “probably a week away from having industrial grade bomb making material.” The claim effectively reversed months of administration messaging. What had been described as a finished threat was now presented as an emergency.

White House Press Secretary Karoline Leavitt tried to hold the two positions together. On February 24, 2026, she insisted that the June operation “did, in fact, obliterate Iran’s nuclear facilities,” while also acknowledging that “Iran may try again to establish a nuclear programme.” The formulation treated obliteration as both complete and reversible, final and temporary, decisive and insufficient. This was a collapse in the logic of state communication.

Three actors in detail

Trump built the operational narrative. Hegseth supplied institutional military authority. Vice President J.D. Vance provided the strategic framing. Together, they turned contradiction into doctrine.

Trump’s pattern was not primarily about accuracy but about utility. The administration often appeared to say whatever was necessary in the moment to defend its preferred course of action. If the issue was the success of a past strike, the Iranian nuclear threat had been eliminated. If the issue was the need for escalation, the same threat had returned in urgent form.

Hegseth gave this logic the language of military necessity. On March 4, 2026, speaking from the Pentagon podium, he declared: “The mission is laser-focused: obliterate Iran’s missiles and drones and facilities that produce them, annihilate its navy and critical security infrastructure, and sever their pathway to nuclear weapons. Iran will never possess a nuclear bomb.” Yet the administration had already claimed that Iran’s pathway to a nuclear weapon had been severed months earlier. Hegseth was therefore presenting as an ongoing mission what his own department had previously described as an accomplished fact.

Vance’s role was to translate the campaign into a broader national security argument. In public remarks during 2026, he argued that U.S. strikes had significantly degraded Iran’s conventional military capabilities, describing its forces as effectively unable to threaten the United States in the way they previously could. He also emphasized the administration’s core justification for the campaign: preventing what he described as “the worst people in the world” from acquiring a nuclear weapon, framing this as a central and enduring U.S. national security objective. 

This contained the same internal tension. If Iran’s conventional military had been effectively destroyed, and if its nuclear pathway had already been eliminated, then the case for continued escalation required a new explanation. Instead, the administration relied on the same language of existential danger that it had earlier claimed to have neutralized.

Apocalyptic language

The Iran war also produced a form of presidential rhetoric that was striking even by the standards of modern American crisis politics. On April 7, 2026, Trump threatened that “a whole civilization will die tonight” unless Iran accepted a deal. The statement followed a profanity-laced Truth Social post demanding that Iran “Open the Fuckin’ Strait,” as well as a public announcement that he had a plan to destroy every bridge and power plant in the country by midnight.

Approximately ninety minutes before the self-imposed deadline expired, Trump announced a two-week ceasefire after intervention by Pakistani Prime Minister Shehbaz Sharif.

The sequence revealed a deeper strategic problem. Threats derive their power from credibility. When a president issues civilizational ultimatums and then suspends them after a diplomatic intervention, the coercive value of future threats declines. Adversaries learn to wait. Allies learn not to mobilize too quickly. The language of annihilation, once used and then withdrawn, becomes less a signal of resolve than a performance of pressure.

The international reaction reflected that concern. Pope Leo XIV described the threats as “truly unacceptable.” French Foreign Minister Jean-Noël Barrot warned that attacks targeting civilian and energy infrastructure could constitute a war crime. The administration’s refusal to rule out the use of a nuclear weapon against Iran deepened the alarm. For allies, such ambiguity was not strategic sophistication. It was the absence of the clarity required for planning, coordination, and legal accountability.

The consequences extended beyond the Iran file. They struck at the architecture of U.S.-led alliances.

Military alliances are not sustained by treaties alone. They depend on the belief that commitments mean what they say, that consultations are meaningful, and that the leading power in the alliance is predictable under stress. The Trump administration weakened all three assumptions.

Alliance fracture

Former U.S. Ambassador to NATO Ivo Daalder put the matter plainly: “Military alliances are at their core, based on trust: the confidence that if I am attacked, you will come help defend. It’s hard to see how any European country will now be able and willing to trust the United States to come to its defense. Hope, perhaps. But they can’t count on it.”

Trump launched the Iran war without consulting Congress, without securing public consent, and without meaningful consultation with U.S. allies. He then demanded that those allies help manage the consequences of a war they had not been allowed to shape.

The Carnegie Endowment for International Peace concluded that Europeans would no longer be able to trust this administration’s commitment to NATO, and that repeated threats had hollowed out any sense of alliance solidarity. Hegseth described European allies as “ungrateful” and warned that they might need to “start learning how to fight on their own.” Marco Rubio said the United States would need to “re-examine the value of NATO.”

Max Bergmann of the Center for Strategic and International Studies captured the cumulative effect: “The Europeans are fed up. There’s an exasperation, but there’s also a growing sense that Trump is pushing the limits that make this something of a different order. I know the analogy of a divorce has been used a lot — but that may be because it is quite apt when what we’re seeing is much like the breakup of a long marriage.”

Precedents are real

This is not to suggest that American foreign policy was ever free of contradiction. The historical precedents are real. The Gulf of Tonkin Resolution of 1964 was passed on the basis of an incident that the Johnson administration knew to be ambiguous at best and misleading at worst. The 2003 invasion of Iraq was justified by intelligence claims about weapons of mass destruction that were never found; Colin Powell later called his presentation to the United Nations a “blot” on his record. Richard Nixon’s declaration in October 1972 that “peace is at hand” was followed by months of further bombing in Vietnam.

In each case, official statements about military necessity were exaggerated, distorted, or later discredited. American power has long carried a credibility problem, especially in the Global South, where the gap between U.S. rhetoric and U.S. conduct has often been most visible.

But the current pattern has distinct features. The first is the velocity of contradiction. The distance between “completely obliterated” and “a week away from having bomb-making material” was only eight months, and the same officials advanced both claims. Previous administrations often depended on the passage of time, bureaucratic opacity, or historical distance to obscure contradictions. This administration compressed the cycle into a matter of months, sometimes even days.

The second is the platform architecture. Earlier contradictions were mediated through official speeches, diplomatic channels, classified briefings, and carefully drafted statements. Ambiguity could be preserved. Trump’s Truth Social posts, by contrast, were direct, unfiltered, timestamped, and instantly archived. The contradiction was not hidden in the machinery of government. It was publicly displayed.

The third is the treatment of contrary evidence. When the Defense Intelligence Agency reportedly produced a classified assessment that complicated the administration’s obliteration claims, its director was removed. The White House later moved to limit classified information sharing with Congress. In previous administrations, the intelligence community sometimes served as an imperfect corrective mechanism. Under this pattern, the corrective itself became a target.

The fourth is the explicit pressure placed on allies. Threats to annex allied territory, demands that allied navies join a war they had not been consulted on, and public insults directed at allied leaders were not accidental deviations from U.S. alliance management. They reflected a more transactional doctrine. Where earlier administrations often operated under the so-called “Pottery Barn rule” — “you break it, you own it” — the current posture appeared closer to: we broke it, but you own it.

That shift is what makes the damage structural rather than episodic. The Carnegie Endowment framed the dilemma clearly: by treating transatlantic interdependence as a lever of coercion rather than a foundation of shared security, Washington forced Europe to confront a strategic question it could no longer postpone.

Price of disposable word

The price of this rhetoric is credibility, which, once spent, is difficult to recover. Over the past year, the United States has demonstrated through a documented sequence of official statements that its declarations of military success may function less as factual assessments than as political instruments. It has shown that threats of civilizational destruction may be used as negotiating tactics rather than as strategic commitments. It has also shown that institutions designed to test official claims can be weakened or punished when their findings become inconvenient.

The question confronting any future negotiating partner — from Tehran to Tokyo — is therefore not only whether the United States has the power to enforce an agreement. It is whether Washington can offer assurances that others can believe. As Chatham House analysts put it, the central question is whether the United States can “offer credible assurances against renewed strikes and be trusted to uphold them.”

The past year offers an uncomfortable answer. When the same officials declare a nuclear program obliterated and then launch a second war to obliterate it again; when a president threatens civilizational annihilation and then agrees to a ceasefire ninety minutes before his own deadline; when intelligence assessments are treated as political threats rather than institutional safeguards; what remains is not leadership in the traditional sense. It is power untethered from the constraints that make power reliable.

States can manage an adversary they distrust. What they cannot easily manage is an ally they cannot predict.
