Trump claims US strikes prevented Iran from acquiring nuclear weapon

President Donald Trump declared that Iran would have obtained a nuclear weapon if the United States had not launched military strikes during the 2025 conflict. Speaking about the aftermath of Operation Midnight Hammer, Trump framed the attacks on three Iranian nuclear facilities as the decisive action that kept the world from a far darker timeline.

It’s a bold claim, and one that sits uneasily alongside Pentagon assessments suggesting the strikes bought roughly two years of delay, not permanent elimination. Iran has reportedly already begun rebuilding elements of its nuclear program, turning what the administration pitched as a definitive solution into something closer to an expensive stopwatch.

What happened during Operation Midnight Hammer

In June 2025, the US military struck three Iranian nuclear sites: Fordow, Natanz, and Isfahan. Fordow is a uranium enrichment facility buried deep inside a mountain. Natanz has been the centerpiece of Iran’s enrichment program for decades. Isfahan houses uranium conversion infrastructure that feeds the broader nuclear supply chain.

Trump said the strikes “obliterated” these facilities. The president went further, asserting that without these strikes, Iran could have escalated tensions into what he described as a potential World War III scenario.

A Pentagon review conducted in July 2025 offered a more measured take. The assessment estimated that the strikes set back Iran’s nuclear program by approximately two years.

The rebuilding problem

By February 2026, Trump was back making the case for the strikes’ effectiveness. The timing wasn’t coincidental. Reports had emerged that Iran was attempting to reconstruct elements of its nuclear program.

Multiple assessments following the strikes have offered varying perspectives on long-term impact. While the initial Pentagon review pointed to the two-year delay, subsequent analyses debated whether the setback was truly comprehensive or whether certain aspects of Iran’s weaponization research survived in forms that are harder to target with airstrikes.

Negotiations and the nuclear question

As of mid-2026, the US and Iran have engaged in negotiations that produced some agreements, including arrangements around the security of the Strait of Hormuz. About 20% of the global oil supply passes through that narrow waterway. But the nuclear issue itself remains unresolved. Trump referenced ongoing negotiations aimed at preventing Iran from obtaining nuclear weapons, even as Tehran has historically made pledges on nonproliferation that it later walked back or reinterpreted.

The diplomatic backdrop here stretches back to the 2015 JCPOA, the nuclear agreement that the Obama administration negotiated and Trump’s first administration withdrew from in 2018. That withdrawal reimposed sanctions on Iran and is widely viewed as having accelerated Iran’s enrichment activities in the years that followed. By the time Operation Midnight Hammer launched, Iran’s program had advanced well beyond where it stood under the original deal’s constraints.
