Trump Claims Iran Nuclear Promise, Critics Call It Decades Old
President Donald Trump has declared that Iran has “already agreed” not to develop a nuclear weapon, hailing it as a major diplomatic breakthrough in the ongoing U.S.-Iran war. However, nuclear experts and critics have been quick to point out that Tehran has made the same pledge for more than 50 years through multiple international treaties and religious declarations, raising serious questions about the actual significance of Trump’s claim.
The Claim
In a series of interviews, including a conversation with the New York Post’s “Pod Force One” podcast on June 3 and a prior appearance on Fox News with Lara Trump, the president asserted that securing Iran’s commitment to forgo nuclear weapons represents a substantial achievement in peace negotiations. “They’ve already agreed they’re not going to have a nuclear weapon,” Trump told the New York Post, as reported by CNBC. “I mean, now they can change their mind, but that was one of the things they’ve had to agree, they’ve agreed to that. That was the big thing.”
Trump acknowledged that Iran could reverse its position, but framed the agreement as a necessary precondition for any lasting peace deal. The comments come as the U.S.-Iran war, which began on February 28, 2026, approaches its 100th day, with peace talks stalled and the Strait of Hormuz effectively closed, keeping global oil prices elevated.
A Pledge Decades in the Making
Critics were swift to note that Iran’s commitment not to seek nuclear weapons is far from new. Iran was one of the original 62 signatories to the Nuclear Non-Proliferation Treaty (NPT) in 1968, and its parliament ratified the treaty in 1970. The NPT, as detailed by the U.S. Institute of Peace, prohibits non-nuclear signatories from developing or acquiring nuclear weapons and requires monitoring by the International Atomic Energy Agency (IAEA).
Beyond the NPT, Iran’s Supreme Leader Ayatollah Ali Khamenei issued a fatwa in the mid-1990s — reaffirmed in 2003 — declaring nuclear weapons forbidden under Islamic law. Additionally, the 2015 Joint Comprehensive Plan of Action (JCPOA), the nuclear deal from which Trump withdrew in 2018, explicitly states in its first paragraph that Iran “reaffirms that it will under no circumstances ever seek, develop or acquire any nuclear weapons.”
Gary Samore, a veteran arms control expert who served as an NSC official in the Obama administration, dismissed Trump’s characterization. “It’s not much of a concession,” Samore told the New York Times. He noted that the real issue is not the pledge itself, but “how the pledge translates into limits on Iran’s enrichment program.”
Iran’s Response
Iran’s Foreign Ministry declined to comment on Trump’s interview directly, but a government official speaking to CNBC called the president’s words “misleading.” The official emphasized that “Iran is a longstanding member of the NPT, and its nuclear programme has always been exclusively peaceful. Iran has never sought nuclear weapons, and therefore there is nothing new about Iran ‘agreeing not to have’ them.”
Esmaeil Baghaei, the Iranian Foreign Ministry spokesperson, stated on Monday that “no negotiations [have taken place] at this stage on the details of the nuclear issue,” according to Iranian state media.
Broader Context: War and Diplomacy
The nuclear pledge controversy unfolds against the backdrop of a devastating conflict. The White House released a compilation on March 2, 2026, documenting 74 times President Trump has stated that Iran cannot have a nuclear weapon, dating back to 2011 — underscoring the consistency of his position.
Meanwhile, fresh hostilities have spilled into Gulf nations. An Iranian drone and missile attack damaged Kuwait International Airport, resulting in one death and dozens of injuries, as reported by TIME. The United Arab Emirates has called for a unified Gulf response, while the U.S. and Israel continue military operations.
Analysis: Substance or Spin?
The central question raised by experts is whether Trump’s claimed achievement represents genuine diplomatic progress or an attempt to frame longstanding Iranian policy as a new concession. Daniel Benaim, a diplomatic fellow at the Middle East Institute, described the broader dynamic to TIME: “Washington and Iran both seem stuck between war and peace. They’re both intent on applying pressure against the other side and pushing the limits of the pressure they can apply without a return to war.”
Without detailed, verifiable limits on Iran’s enrichment capacity — the kind of restrictions that were central to the JCPOA — the nuclear pledge remains largely symbolic. As the war enters its fourth month, the gap between Trump’s optimistic framing and the complex reality on the ground may prove difficult to bridge.
What’s Next
Peace negotiations continue on an uncertain footing. Trump has sent amended peace terms to Iran, and Secretary of State Marco Rubio testified to Congress that Iran “could negotiate aspects of their nuclear program.” However, with Iran insisting that no detailed nuclear talks have occurred and Gulf states reeling from fresh attacks, the path to a comprehensive agreement remains unclear. The coming weeks will test whether Trump’s claimed “big thing” can be translated into enforceable, verifiable commitments — or whether it will join the long list of nuclear pledges that have failed to resolve the underlying tensions.
