How did North Korea get nuclear weapons?
North Korea is known for its bluster and outrageous propaganda, but the nuclear threat posed by the country is taken seriously by those in the know.
The “hermit kingdom” is estimated to have between 13 and 30 nuclear weapons, according to the Institute for Science and International Security. It could have up to 50 by the year 2020.
U.S. President Donald Trump has made it clear that he considers North Korea a legitimate threat. In early April, Trump dispatched the USS Carl Vinson aircraft carrier and its battle group to waters off the Korean Peninsula, and said “major, major conflict” was quite possible.
Tensions have since soared over fears that North Korea may be about to conduct its sixth nuclear weapons test. On Friday, the country sent a letter to American lawmakers, saying any sanctions would only cause its nuclear testing program to “gather greater pace, beyond anyone’s imagination.”
But how did a country as isolated and impoverished as North Korea get its hands on nuclear weapons in the first place?
The Korean War
In 1950, a few months into the Korean War, U.S. President Harry Truman said in a press conference that the use of an atomic bomb was under “active consideration.”
Truman’s nuclear threat remained just that, with the Korean War formally ending in an armistice in 1953. But U.S. forces still laid waste to North Korean targets, dropping over 650,000 tons of bombs and napalm, according to The Korean War: A History.
U.S. Air Force Gen. Curtis LeMay estimated that the U.S. “killed off 20 per cent of the Korean population.”

After the war, North Korea tried to convince its wartime ally China to share its nuclear weapons technologies. Supreme Leader Kim Il-Sung, grandfather of present-day leader Kim Jong-Un, twice asked Chinese ruler Mao Zedong for help but was refused both times, according to The Two Koreas: A Contemporary History.
Denied an easy path to a nuclear bomb, North Korea set about cobbling together an indigenous nuclear weapons program.
It helped that the country already had basic nuclear infrastructure in place.
As a founding member of the Soviet-led Joint Institute for Nuclear Research, North Korea had for years sent its scientists to the Soviet Union for nuclear energy training, according to a timeline compiled by the Nuclear Threat Initiative (NTI).
The Soviets even helped North Korea set up its first nuclear reactor in 1964. The reactor was used to produce radioactive isotopes for medicinal, industrial and research purposes.
But in the years that followed, the country began to explore weapons capabilities, summoning its best scientists home — including from Canada, according to NTI — to work on its fledgling nuclear weapons program.
But while North Korea’s scientists had the technical training, they lacked designs for the highly sophisticated facilities needed to produce nuclear weapons.
Path to a plutonium weapon
In the ‘70s and ‘80s, North Korea set about acquiring sensitive nuclear technologies from Europe, taking advantage of the lack of adequate nuclear information safeguards at the time.
“Lo and behold, it wasn’t long before the North Koreans obtained the design information for that installation… and then eventually over a period of 10 to 15 years, they set that technology up, they deployed the plant, they started to experiment with it and use it,” Mark Hibbs, a senior fellow with the Carnegie Endowment for International Peace, told The Atlantic.
The following year, second-generation Supreme Leader Kim Jong-Il invited a delegation of Western nuclear scientists to North Korea to see its plutonium extraction facility. One of them, American scientist Dr. Siegfried Hecker, revealed in a Google Tech Talk lecture that North Korean officials at one point brought out two marmalade jars of plutonium.
“Inside one was a plutonium powder and the other one had plutonium metal,” Hecker said.
He even held one of the jars in his hand, and concluded from its appearance, weight and warmth that it contained radioactive plutonium.
In 2006, two years after Hecker’s visit, North Korean state media announced the country’s first nuclear weapon test.
By then, the country’s scientists had increasingly begun redirecting their efforts away from plutonium-based nuclear weapons to uranium-based ones, according to NTI. This is because the facilities needed to produce weapons-grade uranium can more easily be hidden underground, away from prying satellites and weapons inspectors.
North Korea wanted to cover all its bases.
The groundwork for North Korea’s uranium nuclear weapons program was laid in the ‘90s, with substantial help from Dr. A.Q. Khan, the pioneer of Pakistan’s atomic bomb program.
Khan orchestrated the clandestine transfer of uranium centrifuges, enrichment machines and technical data to North Korea over a period of several years, according to the book Nuclear Black Markets: Pakistan, A.Q. Khan and the Rise of Proliferation Networks.
According to the book’s author, Mark Fitzpatrick, some of Khan’s deals were likely tied to existing official agreements between the two countries, wherein North Korea provided ballistic missile technologies to Pakistan.

In 2003, the U.S. learned of North Korea’s plans to build a uranium-enrichment facility with Pakistan’s help. The following year, Khan admitted to running a global nuclear proliferation ring, with Iran and Libya among his other clients.
Khan later told German magazine Der Spiegel that he was merely acting on behalf of the Pakistani leadership.
He even released what he claimed was a 1998 letter from Jon Pyong-ho, one of the architects of North Korea’s nuclear program, in which Pyong-ho assures that $3 million has been transferred to Pakistan’s army chief, and asks that Khan dispatch “the agreed documents, components, etc.” via a North Korean emissary.
Khan was later pardoned by Pakistani leader Gen. Pervez Musharraf.
“By freely selling enrichment equipment and putting the designs on computer disks, Khan significantly lowered the technical barriers to nuclear weapons development,” Fitzpatrick wrote.
And no country benefited more from Khan’s largesse than North Korea.
In 2010, Dr. Siegfried Hecker was again invited to North Korea, and was this time taken on a tour of a uranium enrichment facility. He described what he saw as “truly mind-boggling” — around 2,000 centrifuges that appeared to contain highly enriched, weapons-grade uranium.
“[The North Koreans] take whatever they can get, and then they build things themselves, and they do it quite well,” Hecker concluded in his Google Tech Talks lecture.
The Nuclear Silk Road
In early 2015, debris from a North Korean satellite launch were analyzed by experts and found to contain components manufactured in the U.K. and routed through Chinese companies, according to a United Nations Panel of Experts report.
These are but two of several known instances of North Korea evading international sanctions and export controls to procure weapons components.

“North Korea is very creative in the way that it goes about sanctions evasion, and the patterns in which it goes about it vary,” Andrea Berger, a senior researcher with the James Martin Center for Nonproliferation Studies, told Global News.
Berger says North Korea often sends trusted nationals to China to set up front companies, often in collaboration with Chinese citizens. These companies then import equipment from Western manufacturers, who often have no way of knowing that the companies are really fronts controlled by the North Korean regime.
“Let’s say you’re Siemens in Germany and you get a purchase request from ‘Golden Star General Trading Corporation’ in China. You look into that company and it doesn’t have a big web presence — because most Chinese small and medium-sized enterprises don’t — and you assume, after some limited due diligence, that it’s probably fine,” Berger says.
Even Chinese banks themselves often get deceived, she adds.
“The bank account might be under, say, ‘Golden Star General Trading Corporation’ or a Chinese director,” Berger says. “The Bank of China might not immediately be the wiser that there’s a North Korean beneficiary behind that account.”
By covering their tracks in this manner, front companies procure sensitive goods before re-exporting them to North Korea, evading Chinese export controls via misleading shipping labels or creative smuggling techniques.
The racket doesn’t exclusively involve surreptitious front operations, however.
In 2015, a large Chinese company called Shenyang Machine Tools bought equipment from a European manufacturer under the explicit condition that the items wouldn’t be re-sold to North Korea, according to the Institute for Science and International Security.
Shenyang Machine Tools promptly broke the agreement by embedding the products into its own line of industrial machines, which were then exported to North Korea.
The equipment in question is commonly used to manufacture missile parts and uranium centrifuges.
So how does North Korea pay for the expensive parts that it acquires illegally?
Turns out it doesn’t just use front companies to buy — it also uses them to sell its own military products.
Earlier this year, the UN Panel of Experts reported the interception of a shipment of 45 military radios bound for Eritrea. The shipment was sent by a Malaysian-based company called Glocom — which investigators found to be controlled by the North Korean intelligence agency.
Glocom was selling the radios to developing countries at North Korea’s behest — for $8,000 per unit.
Berger, who is familiar with the Glocom investigation, said the company was “being used to facilitate sales of that technology specifically.”
The combination of such clandestine military deals, the sale of missile technologies and the export of coal and minerals have enabled North Korea to fund its nuclear procurement, the UN report suggested.
The “disco ball” warhead
In March 2016, North Korean state media released photographs of Kim Jong-Un standing in front of what it claimed was a miniaturized nuclear warhead “standardized to be fit for ballistic missiles,” Reuters reported.
The object was silver, shiny and shaped like a giant orb. It was roundly mocked on Twitter for resembling a disco ball.
But experts aren’t laughing.
Melissa Hanham, a researcher who analyzes open source data and photos to assess North Korea’s weapons programs, says it’s “plausible” that the object is a working nuclear warhead.
“We can’t see inside it to say, ‘Yes, it is’ or ‘No, it isn’t’ a nuclear warhead,” Hanham told Global News. “But they’ve had five nuclear tests, so it wouldn’t be surprising for them to have that kind of compact warhead by that many tests.
“I can tell you that we’ve measured it a lot, and it does fit into the payload of many of their missiles.”
Hanham admits it’s bizarre that North Korea would let its Supreme Leader stand so close to the real thing, but points out that “there are other photographs of Kim Jong-Un engaging in really dangerous activities that confuse us as well” — referring to photos of him smoking next to a solid-fuel rocket engine and standing underneath a heavy object dangling from a crane.
A legitimate threat
The purported warhead may have been goofy-looking, but it represented one of many milestones in a ramped-up schedule of North Korean nuclear weapons development over the past year and a half.
“North Korea in 2016 spent a lot of time doing a point-for-point refutation of every major narrative of the things it ‘couldn’t do’ in its nuclear missile program,” Berger says.
“All the developments we’re seeing in the nuclear missile program are deeply serious, and the more we continue to laugh about it, the more North Korea will attempt to demonstrate that it has a credible military program that is making rapid advancement.”

That advancement is the result of over half a century of steadily accumulated scientific know-how and single-minded subterfuge, with North Korea taking advantage of lax regulations and shady foreign partners to hoodwink the international non-proliferation regime.
Berger says China’s “conscious negligence” — in relation to both clamping down on front companies and tightening export controls — has resulted in such a huge flow of illicit goods to North Korea that it would take “an enormous effort” to rein it in at this point.
“The problem we have is enormous policy inertia, and very few good ideas of how to address the situation,” Berger says.
Hanham agrees. “I think there are probably still opportunities to slow or disrupt their program, but they’ve already crossed a lot of important thresholds that make it unlikely that they will give up their [nuclear] program entirely,” she says.
“North Korea has shown that it’s dedicated to acquiring nuclear weapons, and it’s very hard to stop any country that’s completely dedicated.”
