In his New Year’s address, the leader of North Korea Kim Jong Un cautioned the United States yet again that his country is ready for a nuclear war. “The entire United States is within range of our nuclear weapons, a nuclear button is always on my desk. This is reality, not a threat,” said Kim. He added a New Year’s resolution of sorts that in 2018, North Korea will be mass-producing more nuclear warheads and ballistic missiles, to “be used only if our society is threatened.”

While bellicose rhetoric is nothing new in the relations between the two countries, there are credible warnings from observers of the situation that a war with North Korea could actually break out. So what do the experts think are the rogue nation’s true military capabilities?

Although it tested 18 missiles, including what seemed like an ICBM, as well as conducted its sixth and most powerful nuclear test in 2017, there are some questions about the extent of North Korea's achievements. It's not certain, for example, what kind of nuclear payload the ICMB can carry or if it can survive reentry. Still the country’s military might should not be underestimated, says Dr. Koh Yu Whan, a professor of North Korea studies at Dongguk University in Seoul.

“Even though the ICBM technology may be somewhat incomplete, Kim is asserting that because he has a nuclear deterrent, the U.S. should not make military threats but engage with North Korea towards peaceful co-existence," said Dr. Whan.

Eleanor Albert from the Council on Foreign Relations, writes in her assessment of the North Korean military that the country’s nuclear weaponry includes somewhere between 15 and 60 bombs, depending on whom you ask. The U.S. intelligence believes in the higher number.

North Korea’s most formidable threat to America could consist of a nuclear warhead carried by its new Hwasong-15 ICBM. In a November 2017 test, the missile hit an altitude of 4,475 kilometers (2,780 miles) and flew 1,000 kilometers (590 miles), as was reported by North Korea. The Hwasong-15’s potential range is 13,000 kilometers (8,100 miles), according to estimates by analysts. That means it could reach anywhere on the U.S. mainland.

The only major questions remaining about these missiles, say observers is that they may have older and unreliable navigation, still from the Soviet Union days. There have been recent defectors, however, who reported that the country has started to use a newer GPS guidance system, so it’s possible the missiles are getting more accurate as well.

The nuclear test carried out by the regime in September 2017 was possibly its largest yet, with the yield of the bomb put at up to 100 kilotons. This can also indicate the country developed a hydrogen bomb. By comparison, the bomb dropped by the U.S. on Hiroshima had a yield of 16 kilotons. 

“We’re going to have to learn to live with North Korea’s ability to target the United States with nuclear weapons,” said Jeffrey Lewis of the Middlebury Institute of Strategic Studies.


Other formidable military capabilities by North Korea may include an an arsenal of 2,500 to 5,000 tons of chemical weapons that include sarin, mustard gas and nerve agents. These can be fired from shells, rockets or missiles and the Korean People Army conducts training to prepare for fighting in a contaminated area.

The country might also have some biological weaponry, able to produce anthrax and smallpox.

As far as its manpower, North Korea has the world’s fourth largest military in the world with more 1.1. million active personnel and another 600,000 in reserve. All citizens are required to serve in its army. 

The U.S. has about 1.3 million active troops, with 865,000 in reserve.

A 2016 report by the South Korean Ministry of National Defense estimated that the North Korean air force consists of 1,300 aircraft. It also has about 5,500 multiple-rocket launchers, 4,300 tanks, 2,500 armored vehicle, 430 combatant vessels, 250 amphibious vessels and 70 submarines.  

By comparison, accordion to the Global Firepower index for 2017, the U.S. has about 6,000 tanks and 13,000 aircraft.

North Korea also has strong cyberattack capabilities, known to have made bold attacks on South Korean banks, Sony Pictures, and even stealing $81 million from a Bangladeshi bank account at the Federal Reserve in 2016. 

Another, perhaps more fantastical, military threat from North Korea may include a nuclear EMP attack - a warning voiced recently by military intelligence experts before a Congressional panel.

No overview of North Korean military might would be complete without mentioning its guiding principles of juche (self-reliance) and songun (politics that places the military first), writes Eleanor Albert.  The military plays a major role in politics and the country’s leader Kim Jong-un sees nuclear weapons as essential to the survival of his regime. 

While it appears that North Korea is truly a country built for war, most analysts would not dare say that the United States cannot soundly and quickly defeat it. America has the world’s most powerful and most modern military. But the costs could be unbearable. It is estimated a war with North korea would claim the lives of 20,000 per day in South Korea, even before the use of nuclear weapons, which are likely to be turned towards the U.S.

And how quickly will they reach for nuclear weapons? Daniel Pinkston, a defense strategy expert in South Korea, thinks since North Korea would not be able to sustain a protracted conventional war against the U.S., it would opt for the nuclear option early.

A landslide is imminent and so is its tsunami

An open letter predicts that a massive wall of rock is about to plunge into Barry Arm Fjord in Alaska.

  • A remote area visited by tourists and cruises, and home to fishing villages, is about to be visited by a devastating tsunami.
  • A wall of rock exposed by a receding glacier is about crash into the waters below.
  • Glaciers hold such areas together — and when they're gone, bad stuff can be left behind.

The Barry Glacier gives its name to Alaska's Barry Arm Fjord, and a new open letter forecasts trouble ahead.

Thanks to global warming, the glacier has been retreating, so far removing two-thirds of its support for a steep mile-long slope, or scarp, containing perhaps 500 million cubic meters of material. (Think the Hoover Dam times several hundred.) The slope has been moving slowly since 1957, but scientists say it's become an avalanche waiting to happen, maybe within the next year, and likely within 20. When it does come crashing down into the fjord, it could set in motion a frightening tsunami overwhelming the fjord's normally peaceful waters .

"It could happen anytime, but the risk just goes way up as this glacier recedes," says hydrologist Anna Liljedahl of Woods Hole, one of the signatories to the letter.

The Barry Arm Fjord is a stretch of water between the Harriman Fjord and the Port Wills Fjord, located at the northwest corner of the well-known Prince William Sound. It's a beautiful area, home to a few hundred people supporting the local fishing industry, and it's also a popular destination for tourists — its Black Sand Beach is one of Alaska's most scenic — and cruise ships.

There have been at least two similar events in the state's recent history, though not on such a massive scale. On July 9, 1958, an earthquake nearby caused 40 million cubic yards of rock to suddenly slide 2,000 feet down into Lituya Bay, producing a tsunami whose peak waves reportedly reached 1,720 feet in height. By the time the wall of water reached the mouth of the bay, it was still 75 feet high. At Taan Fjord in 2015, a landslide caused a tsunami that crested at 600 feet. Both of these events thankfully occurred in sparsely populated areas, so few fatalities occurred.

The Barry Arm event will be larger than either of these by far.

"This is an enormous slope — the mass that could fail weighs over a billion tonnes," said geologist Dave Petley, speaking to Earther. "The internal structure of that rock mass, which will determine whether it collapses, is very complex. At the moment we don't know enough about it to be able to forecast its future behavior."

Outside of Alaska, on the west coast of Greenland, a landslide-produced tsunami towered 300 feet high, obliterating a fishing village in its path.

What the letter predicts for Barry Arm Fjord

"The effects would be especially severe near where the landslide enters the water at the head of Barry Arm. Additionally, areas of shallow water, or low-lying land near the shore, would be in danger even further from the source. A minor failure may not produce significant impacts beyond the inner parts of the fiord, while a complete failure could be destructive throughout Barry Arm, Harriman Fiord, and parts of Port Wells. Our initial results show complex impacts further from the landslide than Barry Arm, with over 30 foot waves in some distant bays, including Whittier."

The discovery of the impeding landslide began with an observation by the sister of geologist Hig Higman of Ground Truth, an organization in Seldovia, Alaska. Artist Valisa Higman was vacationing in the area and sent her brother some photos of worrying fractures she noticed in the slope, taken while she was on a boat cruising the fjord.

Higman confirmed his sister's hunch via available satellite imagery and, digging deeper, found that between 2009 and 2015 the slope had moved 600 feet downhill, leaving a prominent scar.

Ohio State's Chunli Dai unearthed a connection between the movement and the receding of the Barry Glacier. Comparison of the Barry Arm slope with other similar areas, combined with computer modeling of the possible resulting tsunamis, led to the publication of the group's letter.

While the full group of signatories from 14 organizations and institutions has only been working on the situation for a month, the implications were immediately clear. The signers include experts from Ohio State University, the University of Southern California, and the Anchorage and Fairbanks campuses of the University of Alaska.

Once informed of the open letter's contents, the Alaska's Department of Natural Resources immediately released a warning that "an increasingly likely landslide could generate a wave with devastating effects on fishermen and recreationalists."

How do you prepare for something like this?

The obvious question is what can be done to prepare for the landslide and tsunami? For one thing, there's more to understand about the upcoming event, and the researchers lay out their plan in the letter:

"To inform and refine hazard mitigation efforts, we would like to pursue several lines of investigation: Detect changes in the slope that might forewarn of a landslide, better understand what could trigger a landslide, and refine tsunami model projections. By mapping the landslide and nearby terrain, both above and below sea level, we can more accurately determine the basic physical dimensions of the landslide. This can be paired with GPS and seismic measurements made over time to see how the slope responds to changes in the glacier and to events like rainstorms and earthquakes. Field and satellite data can support near-real time hazard monitoring, while computer models of landslide and tsunami scenarios can help identify specific places that are most at risk."

In the letter, the authors reached out to those living in and visiting the area, asking, "What specific questions are most important to you?" and "What could be done to reduce the danger to people who want to visit or work in Barry Arm?" They also invited locals to let them know about any changes, including even small rock-falls and landslides.
