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.”
