(Micah Zenko) The April 24, 1984, edition of the British defense publication Jane’s Defence Weekly informed its readers: “Iran is engaged in the production of an atomic bomb, likely to be ready within two years, according to press reports in the Persian Gulf last week.” Subsequent warnings from U.S. and foreign sources about Iran’s imminent acquisition of a nuclear weapon have been offered over the past four decades. These false guesses are worth bearing in mind as news from the nuclear negotiations in Lausanne, Switzerland, emerges.
More technical “breakout” estimates—the time it would take Iran to compile enough highly-enriched uranium (HEU) to fuel one nuclear weapon—continue to be published, with slightly varying timelines. Setting aside logic, wisdom, and a huge range of assumptions, if you average these five estimates, Iran would require 89.8 days, or three months, if it made a hypothetical rush for one bombs-worth of HEU.

It is essential to recognize that Iran does not currently have a nuclear-weapons program, nor does it possess a nuclear weapon. On February 26, James Clapper, the director of national intelligence, told the Senate Armed Services Committee that Ayatollah Khamenei, the supreme leader of Iran, ended his country’s nuclear weapons program in 2003 and “as far as we know, he’s not made the decision to go for a nuclear weapon.” This repeats the “high-confidence” judgment of the U.S. intelligence community (IC) that was first made in November 2007. Clapper added that Iran “wants to preserve options across the capabilities it would take to build [a nuclear weapon], but right now they don’t have one, and have not made that decision.”
To repeat: Iran does not currently have a nuclear-weapons program, nor does it possess a nuclear weapon. So when a politician, analyst, or pundit mentions an Iranian “nuclear-weapons program,” they are referring to a program that the intelligence community is not aware of. If possible, tell that person to contact the Central Intelligence Agency through its “report threats” website to let the agency’s nonproliferation analysts know about whatever secret information he or she is basing his or her judgment upon.
Iran signed the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) on July 1, 1968. Under the NPT, Iran agreed that it was a non-nuclear weapon state party, which prohibits Iran from receiving, manufacturing, or otherwise acquiring nuclear weapons or nuclear explosive devices. Furthermore, like most other non-nuclear weapons states parties to the treaty, Iran entered into an NPT Safeguards Agreement with the International Atomic Energy Agency (IAEA), which it did in May 1974. The crux of the 12-year dispute between Tehran and the IAEA is whether and to what extent Iran is in violation of its NPT obligations and UN Security Council resolution demands. As IAEA directors general have repeated, most recently Yuki Amano last week, the inspection agency has never received adequate clarifying information about the “possible military dimensions” of Iran’s nuclear program.
Nuclear Weapons Capabilities by Country
While Iran has no bomb or nuclear-weapons program, nine other countries do, including five that also signed the NPT. Under the treaty, the five signatoriespledge to “pursue negotiations in good faith on effective measures relating … to nuclear disarmament.” So while the world is focused on the nonproliferation requirements of a country with zero bombs, keep in mind the promises that remain unfulfilled from those countries with 9,835 of bombs, as well as the four countries that are nuclear outliers.
