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.”

Japan puts military on alert for possible North Korean missile test

TOKYO (Reuters) – Japan has put its military on alert for a possible North Korean ballistic missile launch after indications it is preparing for a test firing, two people with direct knowledge of the order told Reuters on Friday.

“Increased activity at North Korea’s missile site suggests that there may be a launch in the next few weeks,” said one of the sources, both of whom declined to be identified because they are not authorized to talk to the media.

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

A missile test coming so soon after the nuclear test would raise concern that North Korea plans to fit nuclear warheads on its missiles, giving it the capability to launch a strike against rival South Korea, Japan and possibly targets as far away as the U.S. West Coast.

Japan’s Minister of Defense Gen Nakatani has ordered Aegis destroyers that operate in the Sea of Japan to be ready to target any North Korean projectiles heading for Japan, the sources said.

A Defense Ministry spokesman declined to say whether PAC-3 batteries and the Aegis destroyers had been deployed to respond to any threat from North Korea.

Nakatani, asked in a press briefing whether Japan would shoot down any North Korean missile, said: “We will take steps to respond, but I will refrain from revealing specific measures given the nature of the situation.”

The advanced Aegis vessels are able to track multiple targets and are armed with SM-3 missiles designed to destroy incoming warheads in space before they re-enter the atmosphere and fall to there targets.

Japan also has Patriot PAC-3 missile batteries around Tokyo and other sites to provide a last line of defense as warheads near the ground.

Rather than a direct attack, however, Japan is more concerned that debris from a missile test could fall on its territory.

U.S. says redesigned missile defense interceptor aces test

WASHINGTON (Reuters) – The U.S. Missile Defense Agency on Thursday said it conducted a successful test of the ground-based U.S. missile defense system managed by Boeing Co aimed at demonstrating the effectiveness of a redesigned “kill vehicle” or warhead built by Raytheon Co.

The test purposely did not include an intercept by a ground-based interceptor launched from Vandenberg Air Force Base in California, but was designed to observe the in-flight performance of the redesigned components and collect data on countermeasures carried by the target, according to statements by the agency and the companies involved.

Raytheon’s exoatmospheric kill vehicle, or EKV, is built to destroy incoming ballistic missiles by colliding them while they are still in space, a concept called “hit to kill.”

Thursday’s test was designed to demonstrate the ability of new “divert thrusters” that were developed by Raytheon to maneuver the warhead after a test failure several years ago.

The test, which involved various elements of the U.S. ballistic missile defense system, took place as U.S. officials said North Korea appeared to be preparing for a possible space launch that could advance its development of intercontinental ballistic missiles.

News of the possible North Korean space launch comes weeks after a fourth nuclear test conducted by Pyongyang on Jan. 6 that has raised concerns worldwide.

MDA said program officials would evaluate the performance of the U.S. missile defense system during Thursday’s test using telemetry and other data gathered during the test.

Raytheon’s EKV has an advanced, multi-color sensor used to detect and discriminate incoming warheads from other objects in space. It has its own propulsion, communications link, discrimination algorithms, guidance and control system and computers to support target selection and intercept.

Riki Ellison, founder of the nonprofit Missile Defense Advocacy Alliance, said the test demonstrated new technology developed to make the EKV more reliable, which in turn would allow the U.S. military to shoot fewer interceptors at each incoming missile threat.

He said the successful test would “provide confidence to our public, reliability to the NORTHCOM (U.S. Northern Command) commander and deterrence against North Korea,” he said.

Ellison urged U.S. officials to add 10 more ground-based interceptors to the California site to provide an additional layer of defense for Hawaii and the western United States.

The U.S. military is already adding 14 interceptors to the 30 already in place, but those missiles will go to the other interceptor site in Alaska.

‘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.

Iran’s supreme leader welcomes sanctions lift, warns of U.S. ‘deceit’

DUBAI (Reuters) – Iran’s Supreme Leader Ayatollah Ali Khamenei on Tuesday welcomed the lifting of international sanctions against Iran, but warned that Tehran should remain wary of its old enemy the United States.

State television reported that Khamenei wrote to President Hassan Rouhani to congratulate him on implementing the nuclear deal, which resulted in U.S., European Union and United Nations sanctions being lifted over the weekend.

In his first comments since the deal took effect, Iran’s highest authority made clear that Washington should still be treated with suspicion. He made no mention of a surprise prisoner exchange that also took place this weekend.

“I reiterate the need to be vigilant about the deceit and treachery of arrogant countries, especially the United States, in this (nuclear) issue and other issues,” Khamenei said.

“Be careful that the other side fully meets its commitments. The comments made by some American politicians in last two, three days are suspicious,” he added.

Republican candidates for the U.S. presidency have criticized the deal, and some Iranian officials fear Washington could walk away from the deal when President Barack Obama leaves office in early 2017.

Hopes for a broader rapprochement between the two countries were dashed on Sunday when Washington slapped new sanctions on companies accused of supporting Iran’s ballistic missile program, drawing an angry response from Iranian officials.

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.

Iran says it removes Arak reactor core in key nuclear deal step

ANKARA (Reuters) – Iran has removed the sensitive core of its Arak nuclear reactor and U.N. inspectors will visit the site on Thursday to verify the move crucial to the implementation of Tehran’s atomic agreement with major powers, state television said on Thursday.

Removal of the core from the Arak reactor will largely eliminate its ability to yield nuclear bomb-grade plutonium, and was one of the toughest issues to resolve in the long nuclear negotiations with the six powers.

“The core vessel of the Arak reactor has been removed … and IAEA inspectors will visit the site to verify it and report it to the IAEA … We are ready for the implementation day of the deal,” spokesman for Iran’s Atomic Energy Organisation Behrouz Kamalvandi said.

Kamalvandi said “Implementation Day,” when Iran will start to get relief from international sanctions in exchange for curtailing its nuclear program under the July 2015 agreement, would come “very soon.”

In Washington, State Department spokesman John Kirby concurred, saying “I do think we’re very close” to Implementation Day.

Kirby also confirmed that concrete had been poured into the core of the reactor. Secretary of State John Kerry said on Wednesday his Iranian counterpart had told him the core had been removed and would be filled with concrete and destroyed.

Under the deal, international sanctions against Iran will be lifted once the IAEA confirms Iran has met its nuclear commitments. Iranian officials expect the IAEA report on this to be issued on Friday. The Vienna-based U.N. watchdog has so far declined to comment on the report.

Iran’s Foreign Minister Mohammad Javad Zarif and the European Union’s Federica Mogherini will issue a statement on Saturday or Sunday on the “Implementation Day” of the nuclear deal and the lifting of sanctions, according to Iranian officials.

The U.S. and EU sanctions have choked off nearly 1.5 million barrels per day of Iranian oil exports since early 2012, reducing its oil exports by 60 percent to around 1 million barrels a day.

Tehran has drastically reduced the number of centrifuges installed at the Fordow and Natanz enrichment sites within the last few months, and shipped tonnes of low-enriched uranium materials to Russia.

“The core’s holes will be filled with concrete … The core was initially supposed to be cut into parts but we did not accept it as we want to keep it as the symbol of Iran’s nuclear industry,” Kamalvandi told state TV.

Analysis shows North Korea faked sub-launched missile test footage

SEOUL (Reuters) – Footage of a North Korean submarine-launched ballistic missile (SLBM) test released by Pyongyang two days after it announced it had conducted the country’s fourth nuclear test last week was faked, according to an analysis by a California-based think tank.

In defiance of a UN ban, the isolated country has said it has ballistic missile technology which would allow it to launch a nuclear warhead from a submarine, although experts and analysis of North Korean state media cast doubt on the claim.

North Korean state television aired footage on Friday of the latest test, said to have taken place in December. Unlike a previous SLBM test in May, it had not been announced at the time.

“The rocket ejected, began to light, and then failed catastrophically,” said Melissa Hanham, a senior research associate at the California-based Middlebury Institute’s James Martin Centre for Nonproliferation Studies (CNS).

South Korea’s military said on Saturday North Korea appeared to have modified the video and edited it with Scud missile footage from 2014 although an official told Reuters that the ejection technology might have improved since the May test.

The CNS analysis shows two frames of video from state media where flames engulf the missile and small parts of its body break away.

“North Korea used heavy video editing to cover over this fact,” Hanham said in an email.

“They used different camera angles and editing to make it appear that the launch was several continuous launches, but played side by side you can see that it is the same event”.

North Korean propagandists used rudimentary editing techniques to crop and flip old video footage of an earlier SLBM test and Scud missile launch, the video analysis showed.

The North’s claim that its fourth and most recent nuclear test, conducted last Wednesday, was of a more advanced and powerful hydrogen bomb has drawn skepticism from the U.S. government and experts.

It is also unclear if North Korea has developed a nuclear device small enough to mount on a missile.

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.
