Agency urges nations to ratify bans on nuclear bomb testing

PARIS (Reuters) – North Korea’s recent nuclear test shows a ratification of an international ban on nuclear bomb tests is more urgent than ever, the head of the Vienna-based organization tasked with enforcing the ban said on Monday.

Negotiated in the 1990s, the Comprehensive Nuclear Test Ban Treaty (CTBT) enjoys wide global support but must be ratified by eight more nuclear technology states – among them Israel, Iran, Egypt and the United States – to come into force.

“We must act urgently,” Lassina Zerbo, executive secretary of the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) told reporters in Paris after meeting with French Foreign Minister Laurent Fabius.

Tension rose in East Asia last month after North Korea’s fourth nuclear test, this time of what it said was a hydrogen bomb.

“The only way to stop that is for the CTBT to come into force,” said the head of the organization, which is independent but linked to the United Nations.

Zerbo said the nuclear deal agreed between Iran and six other nations last year could help speed up the process, which “has been dragging on for 20 years”, and that he hoped to organize a meeting at the ministerial level in Vienna in June.

The CTBTO hopes the eight nations that have not ratified the treaty could agree to a roadmap in June, that would include a moratorium in the Middle East, a discussion with North Korea to “bring it toward a moratorium” and a trust agreement between China and the United States.

Zerbo said a U.S. ratification was a priority for President Barack Obama but that “his hands are tied because he doesn’t have a majority in the Senate.”

South Korea suspects North Korea may have attempted cyber attacks

SEOUL (Reuters) – South Korea said on Wednesday it suspected North Korea of attempting cyber attacks against targets in the South, following a nuclear test by the North this month that defied United Nations sanctions.

South Korea has been on heightened military and cyber alert since the Jan. 6 test, which Pyongyang called a successful hydrogen bomb test, although U.S. officials and experts doubt that it managed such a technological advance.

“At this point, we suspect it is an act by North Korea,” Jeong Joon-hee, a spokesman of the South’s Unification Ministry, told a news briefing, when asked about reports that the North might have attempted cyber attacks.

Authorities were investigating, Jeong said, but did not provide further details.

Last week, South Korean President Park Geun-hye said the scope of threats from North Korea was expanding to include cyber warfare and the use of drones to infiltrate the South.

North Korea has been using balloons to drop propaganda leaflets in the South, amid heightened tension on the Korean peninsula since the nuclear test.

Since the test, there have been unconfirmed news reports that the computer systems of some South Korean government agencies and companies had been infected with malicious codes that might have been sent by the North.

Defectors from the North have previously said the country’s spy agency, run by the military, operates a sophisticated cyber-warfare unit that attempts to hack, and sabotage, enemy targets.

South Korea and the United States blamed North Korea for a 2014 cyber attack on Sony Pictures that crippled its systems and led to the leaks of unreleased films and employee data.

At the time, the company was set to release the film, “The Interview”, featuring a fictional plot to assassinate North Korean leader Kim Jong Un.

North Korea has denied the allegation.

In 2013, cybersecurity researchers said they believed North Korea was behind a series of attacks against computers at South Korean banks and broadcasting companies.

‘Doomsday Clock’ countdown still at 3 minutes to midnight, closest since 1984

The countdown to global catastrophe remained at three minutes to midnight, scientists announced Tuesday, warning the planet was still perilously close to experiencing a disaster.

The Bulletin of the Atomic Scientists, which sets the hands of a metaphorical Doomsday Clock, announced the countdown would stay at the position it reached last year. It’s the closest the clock has been to midnight, or a catastrophic event, since the height of the Cold War in 1984.

The nonprofit determines the clock’s position after analyzing threats to human existence, particularly nuclear weapons and climate change. Only once have the hands ever been closer to midnight, a seven-year stretch during the 1950s following the world’s first hydrogen bomb tests.

In a statement, the Bulletin hailed the Iran nuclear deal and Paris Agreement on climate change, both of which were approved last year, as “major diplomatic achievements,” though said they “constitute only small bright spots in a darker world situation full of potential for catastrophe.”

The Bulletin said the Joint Comprehensive Plan of Action, the formal name for the deal that restricts Iran’s ability to develop atomic weapons, was overshadowed by rising tensions between Russia and the United States, both of whom are modernizing their nuclear arsenals, and the fact that China, Pakistan, India and North Korea are working to bolster their atomic capabilities.

The Bulletin called the Paris Agreement, a pledge signed by nearly 200 countries that aims to reduce carbon emissions and keep global temperatures from reaching long-feared levels, another important development. But the scientists noted it’s still not clear exactly how the nations will meet that goal, and the agreement was signed during the hottest year on record.

The scientists also cited ongoing conflicts in the Ukraine and Syria in their statement.

“The world situation remains highly threatening to humanity, and decisive action to reduce the danger posed by nuclear weapons and climate change is urgently required,” the Bulletin said.

The Bulletin was founded in 1945 by scientists who helped builds the world’s first atomic bomb. It established the Doomsday Clock two years later, and decides where to set its hands each year.

The clock can be moved back if the global outlook improves, and moved up if it worsens.

The closest the clock has ever been to midnight was from 1953-59, when the Bulletin said the world was only two minutes from doomsday following the hydrogen bomb tests. Conversely, the clock reached a record 17 minutes to midnight from 1991-94 after the Cold War subsided.

The clock was set at five minutes to midnight in 2012, but the Bulletin adjusted it last year because of climate change and nuclear weapons. In Tuesday’s statement, the Bulletin expressed “dismay” that world leaders had still not taken more aggressive steps to address those issues.

“When we call these dangers existential, that is exactly what we mean: They threaten the very existence of civilization and therefore should be the first order of business for leaders who care about their constituents and their countries,” the Bulletin said in its statement.

The International Campaign to Abolish Nuclear Weapons echoed those calls.

“The Bulletin’s warning should be taken seriously by world leaders,” the campaign’s executive director, Beatrice Fihn, said in a statement.“The risk of use of nuclear weapons is on the rise. If a nuclear weapon was detonated, the effects would be devastating and the international community would be unable to cope with the aftermath. The status quo is no longer an option.”

U.S. weighs making Hawaii missile test site operational

WASHINGTON (Reuters) – The U.S. military has stepped up discussions on converting its Aegis missile defense test site in Hawaii into a combat-ready facility that would bolster American defenses against ballistic missile attacks, according to sources familiar with the discussions.

The proposal, which has been discussed sporadically for several years, was given fresh impetus by North Korea’s fourth nuclear test on Jan. 6 and by recent strides in China’s missile technology capabilities, said current and former U.S. military officials, congressional aides and other sources.

A Chinese official in Washington suggested that Beijing would see such a U.S. move as counter-productive to relations.

Aegis, developed by Lockheed Martin Corp for use on U.S. Navy destroyers, is among the most advanced U.S. missile defense systems, integrating radars, software, displays, weapons launchers and missiles.

Setting up its land version — Aegis Ashore — in Hawaii and linking it with Aegis destroyers would add a permanent missile defense site to the Pacific, providing an extra layer of protection for the U.S. islands and the West Coast at a time when North Korea is improving its missile capabilities.

Ground-based interceptors in Alaska and California provide the current defense for Hawaii and the continental United States against missile attacks.

The Navy also relies on deploying Aegis-equipped destroyers based on U.S. intelligence warnings about imminent threats. North Korea’s development of mobile missile launchers has made it more difficult to predict launches in advance.

To make the test site combat-ready, the U.S. military would need to add personnel, stockpile live missiles and beef up security, at an estimated cost of around $41 million, said the sources, who were not authorized to speak publicly.

It would also need to integrate the site into the larger U.S. ballistic missile defense system, with control likely shifting from the Pentagon’s Missile Defense Agency to the U.S. Navy, the sources said.

U.S. Navy Admiral Harry Harris, commander of U.S. Pacific Command, has been engaged in high-level discussions about ways to protect Hawaii, Guam and the continental United States from threats like North Korea, his spokesman, Captain Darryn James told Reuters.

James said no decisions had been made, but the Aegis Ashore site in Hawaii had a “proven test capability.”

“Admiral Harris is always exploring options to forward deploy and operationalize the latest advancements in ballistic missile defense technologies in the Pacific, where we face increasingly sophisticated threats to the homeland,” James said.

It remains unclear when the U.S. administration could reach a decision, but implementing the changes could be done swiftly, the sources said.

STRENGTHENING THE SHIELD

North Korea’s nuclear test in January underscored U.S. concerns that the secretive state has the ability to place a bomb on a long-range ballistic missile that could reach the U.S. West Coast.

Any moves to boost missile defenses could inflame growing military rivalry between China and Washington and its allies.

Converting the site on Hawaii’s Kauai island into combat use could rankle China at a time of heightened tensions with Washington over the disputed South China Sea. Beijing has already expressed concern about the possible deployment of the mobile U.S. Terminal High Altitude Area Defense (THAAD) system to South Korea.

Zhu Haiquan, spokesman for the Chinese Embassy in Washington, said Beijing believed the nuclear proliferation issue would be best resolved diplomatically.

“All measures seeking to increase military capacities will only intensify antagonism and will not help to solve the problem,” he said when asked about the possible U.S. move.

“China hopes the relevant country will proceed on the basis of regional peace and stability, adopt a responsible attitude and act prudently in regard to the anti-missile issue.”

Russia, meanwhile, has repeatedly objected to the U.S. Aegis Ashore site in Romania, which is due to become operational in the coming weeks. A similar site is due to open in Poland in 2018.

The Missile Defense Agency explored the prospect of putting the Hawaii test site into full operation in a classified report to Congress in September 2014, according to one of the sources.

Congress requires the agency to update its estimate of the cost, feasibility and effectiveness of adding more Aegis Ashore sites this spring.

The Aegis Ashore test site in Hawaii completed its first intercept test in December, using a Raytheon Co Standard Missile-3 Block 1B to destroy a target that replicated an Iranian Ghadr-110 medium-range missile.

Riki Ellison, who heads the non-profit Missile Defense Advocacy Alliance, said the new Aegis installation would in effect give the U.S. military three chances to shoot down a missile aimed at Hawaii, up from one currently.

“If you have the assets on the island, why not use them to protect against possible missile attacks from North Korea?” Ellison said.

The December test proved the Aegis Ashore system could fire two different Raytheon Co missiles — one inside the earth’s atmosphere and one outside — at an enemy missile.

Expansion of military operations in Hawaii have sparked protests by residents in the past.

But Hawaii Representative Mark Takai, a Democrat and member of the House Armed Services Committee, said the conversion is “the best way to ensure we have protection for Hawaii’s critical defense infrastructure against increasingly belligerent actors that threaten our country.

North Korea says peace treaty, halt to exercises would end nuclear tests

SEOUL (Reuters) – North Korea on Saturday called for the conclusion of a peace treaty with the United States and a halt to U.S. military exercises with South Korea to end its nuclear tests.

The isolated state has long sought a peace treaty with the United States, as well as an end to the exercises by South Korea and the United States, which has about 28,500 troops based in South Korea.

“Still valid are all proposals for preserving peace and stability on the peninsula and in Northeast Asia including the ones for ceasing our nuclear test and the conclusion of a peace treaty in return for U.S. halt to joint military exercises,” North Korea’s official KCNA news agency cited a spokesman for the country’s foreign ministry as saying early on Saturday.

Asked if the United States would consider a halt to joint exercises, U.S. State Department spokesman John Kirby said it had alliance commitments to South Korea.

“We are going to continue to make sure the alliance is ready in all respects to act in defense of the South Korean people and the security of the peninsula,” he told a regular news briefing.

Asked earlier this week about North Korea’s call for a peace treaty, the State Department reiterated its position that it remained open to dialogue with North Korea but said “the onus is on North Korea to take meaningful actions toward denuclearization and refrain from provocations.”

The two Koreas remain in a technical state of war since their 1950-53 conflict ended in a truce, not a peace treaty.

North Korea said on Jan. 6 it had tested a hydrogen bomb, provoking condemnation from its neighbors and the United States.

Experts have expressed doubt that the North’s fourth nuclear test was of a hydrogen bomb, as the blast was roughly the same size as that from its previous test, of a less powerful atomic bomb, in 2013.

Pyongyang is under U.N. sanctions for its nuclear and missile programs.

South Korea calls for ‘bone-numbing’ sanctions on North for nuclear test

SEOUL (Reuters) – South Korea warned North Korea on Wednesday that the United States and its allies were working on sanctions to inflict “bone-numbing pain” after its latest nuclear test, and called on China to do its part to rein in its isolated neighbor.

With tension high on the border after the North’s fourth nuclear test on Wednesday last week, South Korean forces fired shots toward what Yonhap News Agency said was a suspected North Korean drone.

It returned to the North after the shots, South Korean military officials told Reuters.

The North’s nuclear test has angered both China and the United States and again raised questions about what can be done to stop its development of nuclear weapons.

The World Economic Forum withdrew its invitation for North Korea’s foreign minister to attend its annual Davos meeting, which was to have been the country’s first participation in the event in 18 years, because of the nuclear test.

North Korea said it had tested a powerful hydrogen bomb but the United States and various experts doubt that, as the blast was roughly the same size as that from its previous test, of an atomic bomb, in 2013.

The U.S. House of Representatives voted nearly unanimously on Tuesday to pass legislation to broaden sanctions on the North.

But apparently unperturbed by the prospect of further international isolation, North Korean leader Kim Jong Un called for an expansion of the size and power of his country’s nuclear arsenal, urging the “detonation of more powerful H-bombs”, the North’s state media reported.

South Korean President Park Geun-hye said more “provocations” by the North including “cyber-terrorism” were possible and new sanctions should be tougher than previous ones. She did not give specifics.

“We are cooperating closely with the United States and allies to come up with effective sanctions that will make North Korea feel bone-numbing pain, not only at the Security Council but also bilaterally and multilaterally,” she said in a speech.

Park said South Korea and China were discussing a U.N. Security Council resolution on North Korea, noting that China has stated repeatedly that it would not tolerate the North’s nuclear program.

China is the North’s main ally and trade partner but it has made clear it opposes its bombs, while China’s ties with South Korea have grown increasingly close in recent years.

“I am certain that China is very well aware if such a strong will isn’t followed by necessary steps, we will not be able to stop the North’s fifth and sixth nuclear tests and we cannot guarantee true peace and stability,” Park said.

“I believe the Chinese government will not allow the situation on the Korean peninsula to deteriorate further.”

Sung Kim, the special U.S. representative for North Korea policy, met with his South Korean and Japanese counterparts in Seoul on Wednesday and said the three agreed that a “meaningful” new sanctions resolution is needed from the Security Council.

“I hope the Chinese authorities agree with us that we simply cannot take a business as usual approach to this latest provocation. We will be working very closely with them to come up with a meaningful resolution,” he said.

‘FINANCIAL PRESSURE’

China rejects complaints it is not doing enough on North Korea. In Beijing, Foreign Ministry spokesman Hong Lei said China’s efforts toward a denuclearized Korean peninsula would continue.

“This is in everyone’s interests and is everyone’s responsibility, including China and South Korea,” he said.

The U.S. House sanctions measure passed by 418-2 and Senate leaders expect to consider a similar bill shortly.

The House bill had been introduced in 2015 but was not brought up for a vote until after North Korea’s latest test.

“(The bill) uses targeted financial pressure to isolate Kim Jon Un and his top officials from the assets they maintain in foreign banks, and from the hard currency that sustains their rule,” said Republican Representative Ed Royce, chairman of the House Foreign Affairs Committee and an author of the measure.

To become law, it must be passed by the U.S. Senate and signed by President Barack Obama.

The 28,500 U.S. troops in South Korea have been put on high alert as a noisy propaganda battle is played out across the heavily fortified border with the North.

South Korea, still technically at war with the North since their 1950-53 conflict ended in a truce, not a treaty, has for days been blaring propaganda through loudspeakers across the border.

South Korea’s military said it had found anti-South leaflets in the Seoul area, which it suspects were dropped by North Korean hot air balloons.

South Korean financial regulators met computer security officials at 16 banks and financial institutions and urged vigilance in the face of possible cyber attacks by North Korea, although none has been detected.

U.S. flies B-52 over South Korea after North’s nuclear test

SEOUL (Reuters) – The United States deployed a B-52 bomber on a low-level flight over its ally South Korea on Sunday, a show of force following North Korea’s nuclear test last week.

North Korean leader Kim Jong Un maintained that Wednesday’s test was of a hydrogen bomb and said it was a self-defensive step against a U.S. threat of nuclear war.

North Korea’s fourth nuclear test angered both China, its main ally, and the United States, although the U.S. government and weapons experts doubt the North’s claim that the device was a hydrogen bomb.

The massive B-52, based in Guam and capable of carrying nuclear weapons, could be seen in a low flight over Osan Air Base at around noon. It was flanked by two fighter planes, a U.S. F-16 and a South Korean F-15, before returning to Guam, the U.S. military said in a statement.

Osan is south of Seoul and 48 miles from the Demilitarised Zone that separates the two Koreas. The flight was “in response to recent provocative action by North Korea”, the U.S. military said.

In Washington, White House Chief of Staff Denis McDonough said on Sunday the flight underscored to South Korea “the deep and enduring alliance that we have with them.”

“Last night was a step toward reassurance in that regard and that was important,” McDonough said on CNN’s “State of the Union.”

He said the United States would continue to work with China and Russia, as well as allies Japan and South Korea, to isolate the North until it lives up to its commitments to get rid of its nuclear weapons.

“Until they do it they’ll remain where they are, which is an outcast unable to provide for their own people,” McDonough said.

China has publicly supported a denuclearised Korean Peninsula, and the United States will “make sure that they understand that a nuclear North Korea is not a stable scenario,” he said.

After the North’s last test, in 2013, the United States sent a pair of nuclear-capable B-2 stealth bombers over South Korea. At the time, the North responded by threatening a nuclear attack on the United States.

The United States is also considering sending a nuclear-powered aircraft carrier to waters off the Korean peninsula next month to join a naval exercise with Seoul, South Korea’s Yonhap news agency reported without identifying a source. However, U.S. Forces Korea officials said they had no knowledge of the plan.

The two Koreas remain in a technical state of war after their 1950-53 conflict ended in a truce, not a peace treaty, and the United States has about 28,500 troops based in South Korea.

An editorial in the North’s Rodong Sinmun newspaper on Sunday called for a peace treaty with the United States, which is the North’s long-standing position. “Only when a peace treaty is concluded between the DPRK (North Korea) and the U.S. can genuine peace settle in the Korean Peninsula,” state news agency KCNA quoted it as saying.

The United States and China have both dangled the prospect of better relations, including the lifting of sanctions, if North Korea gives up its nuclear weapons.

Earlier on Sunday, KCNA quoted Kim as saying no one had the right to criticize the North’s nuclear tests.

“The DPRK’s H-bomb test … is a self-defensive step for reliably defending the peace on the Korean Peninsula and the regional security from the danger of nuclear war caused by the U.S.-led imperialists,” it quoted Kim as saying.

The North’s official name is the Democratic People’s Republic of Korea.

“It is the legitimate right of a sovereign state and a fair action that nobody can criticize,” he said.

TIMING OF TEST

Kim’s comments were in line with the North’s official rhetoric blaming the United States for deploying nuclear weapons on the Korean peninsula to justify its nuclear program but were the first by its leader since Wednesday’s blast.

The United States has said it has no nuclear weapons stationed in South Korea.

Kim noted the test was being held ahead of a rare congress of its ruling Workers’ Party later this year, “which will be a historic turning point in accomplishing the revolutionary cause of Juche,” according to KCNA.

Juche is the North’s home-grown state ideology that combines Marxism and extreme nationalism established by the state founder and the current leader’s grandfather, Kim Il Sung.

KCNA said Kim made the comments on a visit to the country’s Ministry of the People’s Armed Forces.

South Korea continued to conduct high-decibel propaganda broadcasts across the border into the North on Sunday.

The broadcasts, which include “K-pop” music and statements critical of the Kim government, began on Friday and are considered an insult by Pyongyang. A top North Korean official told a rally on Friday that the broadcasts had pushed the rival Koreas to the “brink of war.”

Daily life was mostly as normal on the South Korean side of the border on Sunday. A popular ice fishing festival near the border attracted an estimated 121,300 people on Saturday and 100,000 on Sunday, Yonhap reported.

North Korea overcomes poverty, sanctions with cut-price nukes

SEOUL (Reuters) – North Korea has developed a nuclear weapons program despite poverty and international sanctions, using home-grown technology and virtually free labor to cut costs, experts said.

South Korean government analysis has put North Korea’s nuclear spending at $1.1 billion to $3.2 billion overall, although experts say it is impossible to make an accurate calculation given the secrecy surrounding the program, and estimates vary widely.

However, the weapons that North Korea has tested thus far are comparatively small and based mostly on less sophisticated fission, or atomic bomb, technology.

The isolated North’s claim that its fourth and most recent test, conducted last week, was of a more advanced and powerful hydrogen bomb has been widely doubted, although experts said it is possible Pyongyang took the intermediate step of boosting an atomic bomb with hydrogen isotopes.

A former South Korean official involved in nuclear diplomacy with North Korea told Reuters previously that it was likely the North’s nuclear program was cutting corners on safety, further driving down costs.

North Korea was at the bottom of a 2011 list on nuclear arms spending by Global Zero, a group campaigning to rid the world of nuclear weapons.

The full cost of Pyongyang’s program that year was estimated by the group at $700 million, making it the lowest spender among nuclear states, beneath Pakistan’s estimated $2.2 billion, although the analysis was made before the North’s two most recent nuclear tests.

By comparison, the United States spent $61.3 billion on nuclear weapons in 2011, according to the report.

Construction of the Yongbyon Nuclear Scientific Research Center, North Korea’s main nuclear facility, cost $600-700 million, based on a 2012 estimate, a South Korean defense ministry official told Reuters.

The small reactor at Yongbyon, which began construction in 1979, is based on Soviet-era technology and generates just 5 megawatts of power.

“Actually, what they spend isn’t that much,” Kim Min-gyu, a former North Korean diplomat who worked at the North Korean embassy in Moscow until defecting in 2009, told Reuters.

“Their workforce works for free and, except for a few key imported parts, they make everything else”.

TAX THE RICH

Paying for those parts is not easy for a country whose official economy was worth just $28.4 billion in 2014, according to South Korea’s central bank.

But it has turned to a variety of sources for hard currency in the past, including counterfeiting, insurance scams, selling missile parts to the Middle East, and, more recently, exporting manpower abroad under conditions that human rights groups say resemble indentured servitude.

North Korea also boasts a booming unofficial market economy, driven by private trade that has flourished since the devastating famine of the 1990s, giving the state a relatively new source of foreign currency.

That gray economy has eclipsed the official one, experts said, and generates so much wealth that, after previous nuclear tests, wealthy traders known as “donju”, or “masters of money”, were arbitrarily and suddenly taxed by the state to pay for the nuclear program, according to one report.

“After the first three nuclear tests, prominent donju were purged on ‘anti-socialist’ charges and their assets confiscated by the state,” a source inside North Korea told the Daily NK, a Seoul-based website staffed by defectors still in touch with contacts inside North Korea.

In addition, North Korea exported more than $1 billion in minerals last year, mostly coal, to China, its main trading partner, according to Reuters calculations based on Chinese export data.

Although heavily sanctioned, North Korea still sells small arms to buyers who turn to Pyongyang because of a lack of viable alternative supplies, according to a recent report by Andrea Berger at the Royal United Services Institute (RUSI) in London.

It also raises $200-300 million a year sending laborers as far afield as Poland and Mongolia to earn cash, said the Database Center for North Korean Human Rights in Seoul.

Kim Min-gyu, the former diplomat, said laborer salaries are usually used to prop up the Pyongyang economy, and not invested in the nuclear program.

“Since money is completely fungible, you can’t isolate the transactions that go to pay for bombs from those that pay for apartment buildings in Pyongyang,” said Christopher Green, a North Korea expert at Leiden University in the Netherlands.

North Korean Leader Claims Nation is Ready to Detonate Hydrogen Bomb

The leader of North Korea is reportedly claiming the country now has the ability to detonate a powerful hydrogen bomb, though his comments immediately drew skepticism from experts.

The state-run KCNA news agency reported Thursday that Kim Jong-un made the announcement while at the Phyongchon Revolutionary Site, which is significant to the country’s arms history.

According to the KCNA report, Kim said North Korea had evolved into “a powerful nuclear weapons state ready to detonate self-reliant A-bomb and H-bomb to reliably defend its sovereignty and the dignity of the nation.” If true, it would be a landmark development.

Hydrogen bombs rely on a different nuclear reaction than atomic bombs and are known to be much more powerful. South Korea’s Yonhap news agency reported that while Kim has publicly touted on numerous occasions that his country has atomic-bomb capabilities, this appeared to be the first time the leader publicly indicated that North Korea possessed a hydrogen bomb.

Still, experts took Kim’s claim with a grain of salt. The leader is known for making bold claims.

“It’s hard to regard North Korea as possessing an H-bomb. I think it seems to be developing it,” Lee Chun-geun, a research fellow at the Science and Technology Policy Institute, told Yonhap.

The BBC quoted John Nilsson-Wright, the head of the Asia Program at Britain’s Royal Institute of International Affairs, as saying Kim’s comments appeared to be “an attention-grabbing effort to assert North Korean autonomy and his own political authority.”
