Trump describing the state of Iran's military capabilities after the two-month campaign concluded.

In the long and turbulent history of American power projected into the Middle East, a new chapter closed on a Thursday morning in May when Secretary of State Marco Rubio declared the end of Operation Epic Fury — a two-month US-Israel military campaign that dismantled Iran's armed forces, killed Supreme Leader Ali Khamenei, and forced a succession of power in Tehran. The administration framed its actions as both a fulfillment of allied obligations and a demonstration of resolve, particularly around the Strait of Hormuz, where global energy flows had been imperiled. Yet even as the guns fell silent, the deeper question — whether a wounded and newly led Iran would seek nuclear capability or accommodation — remained unanswered, suspended between the language of peace and the memory of overwhelming force.

  • A coordinated US-Israel assault launched February 28 dismantled Iran's military infrastructure and killed Supreme Leader Khamenei, triggering an abrupt and fragile power transition to his son Mojtaba.
  • Iran's disruption of Strait of Hormuz shipping threatened global oil supplies and drew urgent, sometimes private, appeals from multiple nations for American intervention.
  • Rubio and Trump declared total military victory — Iran's navy, air force, and air defenses described as effectively erased — while simultaneously signaling openness to a negotiated path forward.
  • The new leadership in Tehran faces a stark choice: pursue the nuclear ambitions that invited the campaign, or accept a diplomatic framework under the shadow of demonstrated American willingness to act.
  • The administration's closing message was as much warning as announcement — that the operation is over, but the consequences for any further defiance remain very much alive.

On a Thursday morning in May, Secretary of State Marco Rubio stepped before cameras to announce the formal end of Operation Epic Fury, a sweeping two-month military campaign conducted alongside Israel that had fundamentally altered the political landscape of Iran. Launched on February 28, the operation targeted Iran's nuclear program and military infrastructure — and its consequences reached far beyond any battlefield. Supreme Leader Ali Khamenei was killed during the campaign, and his son Mojtaba was installed as successor, a transfer of power occurring at the moment of Iran's greatest vulnerability.

Rubio's announcement carried two distinct tones. He declared the stated objectives achieved, but he also extended a careful olive branch. The administration, he said, preferred peace and a deal — though Iran had not yet chosen that route. The implicit message was clear: the United States had shown what it was willing to do, and the new leadership in Tehran would need to decide what came next.

Much of Rubio's remarks centered on the Strait of Hormuz, through which roughly a fifth of the world's oil flows daily. Iran had disrupted shipping there during the conflict, and the US military had stepped in to guide stranded vessels to safety — a role Rubio framed not as charity but as the natural expression of American power serving American interests. President Trump, characteristically direct, described Iran's military as entirely erased: no navy, no air force, no air defenses.

Yet beneath the declarations of victory, an unresolved tension persisted. The military campaign had achieved its immediate aims and removed Iran's longtime supreme leader. But the underlying question — whether Iran would ultimately pursue nuclear weapons — remained open. Rubio's final warning to Tehran was pointed: Iran should not test the will of the United States under Donald Trump. The operation had ended. The standoff, it seemed, had not.

On an early Thursday morning in May, US Secretary of State Marco Rubio stood before cameras and announced what the Trump administration had been building toward for more than two months: the formal conclusion of Operation Epic Fury, a sweeping military campaign that had reshaped the political landscape of Iran and sent shockwaves through the Middle East.

The operation had begun on February 28, when the United States and Israel launched a coordinated assault aimed at dismantling Iran's nuclear program and military infrastructure. What unfolded over the following weeks was not merely a military action but a cascade of consequences that reached into the highest corridors of power in Tehran. Supreme Leader Ali Khamenei, who had ruled Iran for decades, was killed during the campaign. His death triggered a succession that installed his son, Mojtaba Khamenei, as the new supreme leader—a transition that marked a fundamental shift in the Iranian state's power structure at a moment of maximum vulnerability.

Rubio's announcement carried a dual message. On one hand, he declared victory: the stated objectives had been achieved. On the other, he signaled openness to a different path forward. "We're not cheering for an additional situation to occur," he said. "We would prefer the path of peace. What Trump would prefer is a deal... that is, so far, not the route that Iran has chosen." The language was careful, almost diplomatic, even as it carried an implicit warning. The administration had demonstrated its willingness to use force at scale. The question now was whether Iran's new leadership would read that message.

Much of Rubio's focus turned to a practical concern that had animated the operation from the start: the Strait of Hormuz, the narrow waterway through which roughly a fifth of the world's oil passes each day. During the conflict, Iran had disrupted shipping in the strait, trapping vessels and threatening global energy supplies. Rubio emphasized that multiple nations—some openly, others in private—had asked the United States to intervene. "President Trump stepped up and answered the calls for their help," Rubio said, describing how the US military had begun guiding stranded ships to safety. He framed this not as charity but as an expression of American power deployed in service of American interests. "We're the only ones who can," he said. "Under President Trump, the United States will help our friends. We are going to stand up to rogue regimes like the one in Tehran."

President Trump himself amplified the message with characteristic bluntness. He described Iran's military as effectively erased from existence. "They have no Navy, totally wiped out. They have no Air Force, totally wiped out. They have no anti-aircraft capability," he said, cataloging the destruction with the tone of someone reading a balance sheet. He acknowledged that Iran's leaders were claiming otherwise in public statements, but dismissed those claims as hollow. The point, he suggested, was not what Iran said but what it could actually do. And what it could do, in Trump's assessment, was nothing.

Yet beneath the declarations of victory lay an unresolved tension. The administration had achieved its immediate military objectives and had eliminated Iran's supreme leader in the process. But it had not resolved the underlying question that had driven the operation: whether Iran would pursue nuclear weapons. Rubio's closing warning to Tehran carried the weight of that uncertainty. "It really is important for them to understand that they should not test the will of the United States, at least not under President Donald Trump," he said. "He has proven time and again that he will back up what he says. And if they test him, ultimately, they will lose." The operation was over. The standoff, it seemed, was not.

We achieved the objectives of that operation. We're not cheering for an additional situation to occur. We would prefer the path of peace.

When Rubio says the operation achieved its objectives, what exactly does that mean? What were they trying to accomplish?

Model

Primarily, degrading Iran's military capacity—destroying the navy, air force, air defenses. But also, and this matters, preventing Iran from developing a nuclear weapon. That second part is still unfinished business.

Inventor

And Khamenei's death—was that planned, or did it happen in the course of the campaign?

Model

The source doesn't specify. What we know is that he died during the operation, and his son took over immediately. That's a seismic shift in Tehran's power structure at the worst possible moment for Iran.

Inventor

Why does the Strait of Hormuz matter so much that Rubio keeps returning to it?

Model

Because roughly a fifth of the world's oil moves through that narrow passage. If Iran closes it or disrupts shipping, global energy markets convulse. Other nations asked the US to step in. Trump did. Now the US is positioning itself as the guarantor of that route.

Inventor

But if Iran's military is truly wiped out, why does Trump need to keep warning them?

Model

That's the contradiction, isn't it? Either they're genuinely powerless, in which case warnings are unnecessary. Or there's still something to worry about—maybe asymmetric threats, maybe the new leadership's intentions. The warnings suggest the latter.

Inventor

What happens next? Is this actually over?

Model

Officially, yes. But Rubio left the door open for diplomacy while making clear the US won't tolerate Iranian nuclear development. Iran's new leadership has to decide whether to test that resolve or negotiate. Everything hinges on that choice.
