North Korea, in word and deed, signals how tough negotiations will be

North Korean leader Kim Jong Un, left, prepares to shake hands with South Korean President Moon Jae-in over the military demarcation line at the border village of Panmunjom in Demilitarized Zone on April 27, 2018. After a few months of rapprochement, North Korea abruptly called off scheduled high-level talks with South Korea on Wednesday, May 16, 2018, and warned the U.S. that a planned summit with President Donald Trump could be at risk.

North Korea periodically blows up bits of its nuclear weapons production infrastructure. Back in 2008, it was a cooling tower for a plutonium-production reactor, exploded for the cameras. Ten years later it’s going to be North Korea’s nuclear test site, perhaps. North Korean officials have invited select media to watch explosions meant to seal test site tunnels in late May. Whether this occurs remains open: North Korean officials this week said there might not be a summit between President Trump and Kim Jong-un after all. They’re angry about the way US officials keep talking about complete North Korean denuclearization. But the destruction shows how verification would be at the heart of any deal. The cooling tower wasn’t as crucial as it seemed; Pyongyang already had a secret uranium enrichment plant that could produce fissile material. As for the test site, North Korea might have another, hidden in the mountains. In 2018, it’s Mr. Kim’s intent, not explosions, that remains crucial. And opaque. “Their willingness to dismantle the test site is a positive sign. Whether they are sincere or not remains to be seen,” says Jon Wolfsthal, director of the Nuclear Crisis Group.

How big a deal is North Korea's missile-test "shutdown," really? We look at the complexity of Pyongyang's negotiating style – it just broke off South Korea talks over joint military exercises with the United States – and the care the US will need to use if the Trump-Kim summit is realized.

On June 27, 2008, North Korea blew up a big symbol of its nascent nuclear program, the cooling tower of the plutonium-producing reactor at the Yongbyon nuclear site. First, a cloud of smoke erupted from the beaker-shaped structure. Then explosions ringing the base leveled the remains.

The destruction was meant to symbolize progress in six-party disarmament talks. But good feelings didn’t last. Within weeks a developing deal to end North Korea’s nuclear ambitions fell apart, in part because Pyongyang got a look at sweeping and intrusive US plans for verifying such an agreement.

Almost exactly 10 years later, North Korea is again planning an explosive event meant to showcase its nuclear intentions. North Korean officials say that in late May they will shut down their nuclear test site by blowing up and sealing entrances to tunnels.

Is that a big deal? Not by itself, say some US experts. North Korea may not need to test weapons designs for the foreseeable future. Tunnels could be dug again if necessary. Other, secret test sites might already exist.

Pyongyang remains an opaque, unpredictable negotiations partner – as shown by this week’s sudden threat to cancel the scheduled summit between President Trump and North Korean leader Kim Jong-un. In that context, gestures are difficult to interpret. It’s what happens in hard bargaining that really counts.

“Their willingness to dismantle the test site is a positive sign. Whether they are sincere or not remains to be seen,” says Jon Wolfsthal, a nuclear non-proliferation expert and director of the Nuclear Crisis Group.

Sudden cold after apparent thaw

In the short term, North Korea’s sudden warning that it might still withdraw from the planned leaders’ summit in Singapore was a dose of cold reality for a geopolitical situation that had seemed to be thawing. This wasn’t Mr. Kim smiling and stepping across the border hand-in-hand with South Korean President Moon Jae-in. It was North Korea objecting to US-South Korean air-power exercises, and a North Korean disarmament official rejecting what he said were US efforts to force his nation into “unilateral nuclear abandonment.”

The sudden anger might be an indirect way of attempting to counter Washington’s hard-line rhetoric on the upcoming meeting. National security adviser John Bolton – who drew Pyongyang’s ire by name – has talked of the “Libya solution” to North Korean nuclear weapons. That would mean Pyongyang would simply turn all nuclear material and devices over to US control and wave goodbye.

That’s not going to happen, says Mr. Wolfsthal. But that does not mean negotiations are worthless. It is possible there are phased solutions or less-ambitious agreements to be reached.

“I think that Trump’s optimism was not justified,” says Wolfsthal, referring to the confident way the president has predicted North Korean denuclearization. “But global pessimists are also not justified.”

The destruction of the Yongbyon cooling tower in 2008 is perhaps an example of North Korea’s tough, incremental nuclear negotiating tactics. On the one hand, it was a spectacular, camera-ready event. A valuable asset was rendered inoperative. On the other hand, the cooling tower was perhaps not as crucial as it first appeared.

Though the explosion meant North Korea had lost the ability to produce plutonium, the heart of nuclear weapons, the country was working on secret uranium enrichment plants capable of producing another kind of fissile material. And plutonium production could have been restarted if necessary.

In 2010, North Korean officials invited Siegfried Hecker, former director of the Los Alamos National Laboratory, to visit the Yongbyon site. Its chief engineer told Dr. Hecker that the plutonium-production reactor had been placed in standby status.

“My assessment is that they could resume all plutonium operations within approximately six months,” Hecker wrote after his visit.

Verification will be central

Overhead photography provides evidence that the plutonium production reactor has since restarted, with its cooling water discharge pipe extended far down a nearby river to cover up tell tale heat signatures. In turn, this is evidence for an obvious point: verification arrangements will be central to any North Korean denuclearization agreement.

North Korean activities at its Yongbyon nuclear complex and the test site at Punggye-ri have been well documented by US surveillance capabilities. But over half of the country’s nuclear facilities are outside these two main areas, and some remain unknown, said David Albright, a nuclear inspections expert and president of the Institute for Science and International Security, at a presentation early this week, citing an official source.

For instance, North Korea has one known gas centrifuge uranium enrichment facility at Yongbyon. But many experts have long suspected there is a second, hidden such facility somewhere in the country where North Korean scientists first fiddled with this tricky technology.

It is even possible there is a second test site that has gone undetected by US spy equipment. The official North Korean release discussing the explosion of tunnels referred to Punggye-ri as the “northern” test site, implying the existence of a southern counterpart.

A verification regime for a North Korea nuclear agreement will have to permit access to sites, including military sites; nuclear personnel; and documents, said Mr. Albright, according to PowerPoint slides that accompanied his presentation.

North Korea “needs to make an early concrete demonstration of its commitment to denuclearization. Closing the Punggye-ri Underground Test Site, while welcome, is not sufficient,” according to Albright.

What is the Monitor difference? Tackling the tough headlines – with humanity. Listening to sources – with respect. Seeing the story that others are missing by reporting what so often gets overlooked: the values that connect us. That’s Monitor reporting – news that changes how you see the world.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”
