Will There Ever be an Accounting on North Korea?

Will There Ever be an Accounting on North Korea? Power Line,  John Hinderaker, November 28, 2017

(Someday perhaps, but first we need to deal with matters of real importance — who grabbed whose what, when, where and why? Will he, she or an entity who/which self-identifies as a cow be punished or will Antifa members and other social justice warriors prevail?

Here’s one of my favorite poems by Robert Burns. It has nothing to do with North Korea, its missiles or nukes. Instead, it focuses on matters of apparently more substantial contemporary importance.

Address to the Unco Guid,
Or the Rigidly Righteous.

My son, these maxims make a rule,
An’ lump them ay thegither:
The Rigid Righteous is a fool,
The Rigid Wise anither;
The cleanest corn that e’er was dight
May hae some pyles o’ caff in;
So ne’er a fellow-creature slight
For random fits o’ daffin.
Solomon. (Ecclesiastes vii. 16)
1.
O ye, wha are sae guid yoursel,
Sae pious and sae holy,
Ye’ve nought to do but mark and tell
Your neebours’ fauts and folly,
Whase life is like a weel-gaun mill,
Supplied wi’ store o’ water,
The heapet happer’s ebbing still,
An’ still the clap plays clatter!
2.
Hear me, ye venerable core,
As counsel for poor mortals
That frequent pass douce Wisdom’s door
For glaikit Folly’s portals:
I for their thoughtless, careless sakes
Would here propone defences —
Their donsie tricks, their black mistakes,
Their failings and mischances.
3.
Ye see your state wi’ theirs compared,
And shudder at the niffer;
But cast a moment’s fair regard,
What makes the mighty differ?
Discount what scant occasion gave;
That purity ye pride in;
And (what’s aft mair than a’ the lave)
Your better art o’ hidin.
4.
Think, when your castigated pulse
Gies now and then a wallop,
What ragings must his veins convulse,
That still eternal gallop!
Wi’ wind and tide fair i’ your tail,
Right on ye scud your sea-way;
But in the teeth o’ baith to sail,
It makes an unco lee-way.
5.
See Social-life and Glee sit down
All joyous and unthinking,
Till, quite transmugrify’d, they’re grown
Debauchery and Drinking:
O, would they stay to calculate,
Th’ eternal consequences,
Or – your more dreaded hell to state –
Damnation of expenses!
6.
Ye high, exalted, virtuous dames,
Tied up in godly laces,
Before ye gie poor Frailty names,
Suppose a change o’ cases:
A dear-lov’d lad, convenience snug,
A treach’rous inclination–
But, let me whisper i’ your lug,
Ye’re aiblins nae temptation.
7.
Then gently scan your brother man,
Still gentler sister woman;
Tho’ they may gang a kennin wrang,
To step aside is human:
One point must still be greatly dark,
The moving why they do it;
And just as lamely can ye mark
How far perhaps they rue it.
8.
Who made the heart, ’tis He alone
Decidedly can try us:
He knows each chord, its various tone,
Each spring, its various bias:
Then at the balance let’s be mute,
We never can adjust it;
What’s done we partly may compute,
But know not what’s resisted.

Today North Korea launched an intercontinental ballistic missile that stayed airborne for close to an hour and flew farther than any previously tested by that country. Defense Secretary James Mattis told reporters that the Kim regime now has the ability to hit “everywhere in the world basically.” And, of course, the regime has nuclear weapons.

Further:

The US believes Pyongyang may be able to put a miniaturized warhead on a missile sometime in 2018 — giving it the theoretical capability to launch a missile with a warhead atop that could attack the US.

President Trump inherited the North Korea mess. He told reporters today that North Korea “is a situation that we will handle.” I sincerely hope so, but I have no idea how. Is there any practical way to threaten Kim’s nuclear capability without endangering the 10 million people who live in Seoul, just 35 miles from the border with North Korea? Again, I have no idea.

The North Korea problem has been brewing for a long time. In 1994, the Clinton administration agreed to provide two nuclear reactors and deliver heavy fuel oil to North Korea in exchange for the country giving up its nuclear weapons program. The reactors were never built, but Kim nevertheless snookered Clinton, as North Korea accelerated rather than giving up its nuclear program.

Subsequently, American administrations have kicked the Korean can down the road. Most blameworthy was Barack Obama. Just a few months into Obama’s administration, the North Koreans detonated a series of nuclear devices. President Obama responded with a policy of “strategic patience,” a euphemism for doing nothing and hoping that disaster wouldn’t strike until he was out of office. This was classic Obama: as the increasingly insane North Korean regime drew ever closer to an offensive nuclear capability, he did nothing. Now President Trump is stuck holding the bag.

Millions of lives could be lost because of this feckless history. Meanwhile, our news media have mostly ignored the North Korea issue, preferring to obsess on Roy Moore’s purported 40-year-old failings, whether Press Secretary Sarah Sanders baked a Thanksgiving pie, Al Franken’s tortured meditations on how easy it is to grasp a woman’s bottom by accident, and so on. Will our inept reporters and editors ever bestir themselves to report on how Barack Obama and, to a lesser extent, his predecessors allowed the Kim regime to become such a threat to millions of human lives?

That’s a rhetorical question, of course. They certainly won’t do so if it would reflect badly on their party. Which it would. So don’t hold your breath, and pray that President Trump and his aides will find a way out of the mess that his predecessors helped to create.

North Korean EMP Attack Would Cause Mass U.S. Starvation, Says Congressional Report

October 23, 2017

North Korean EMP Attack Would Cause Mass U.S. Starvation, Says Congressional Report, Forbes

(Please see also, How the electric grid has been compromised. — DM)

A new congressional report contends that a North Korean electromagnetic pulse (EMP) attack on the U.S. would ultimately wipe out 90 percent of the population.

To date, most discussion concerning the North Korean threat has been on whether the rogue state can accurately hit U.S. cities with its ICBMs. But in an EMP attack, such accuracy is not necessary because the pulse radius would be so large, says Peter Vincent Pry, who recently testified about the EMP threat before a congressional Homeland Security subcommittee. His conclusions are that such an EMP attack would wreak havoc across the whole of the continental U.S.

Unlike a conventional ICBM which launches and then goes into a suborbital flight before re-entering Earth’s atmosphere, an EMP warhead need not re-enter Earth’s atmosphere before exploding hundreds of kilometers above its target. Super-EMP weapons are designed to produce a high level of gamma rays, which generate the sort of high-frequency electromagnetic pulse that is most damaging to the broadest range of electronics, the report concludes.

And if the EMP device just happens to be part onboard an orbiting satellite, North Korea need only detonate the device remotely via encoded signal. Pry, Chief of Staff of the now de-funded Congressional EMP Commission, told me that at an altitude of 300 kilometers, the resulting electromagnetic pulse would affect all 48 contiguous states.

A warhead fused for an EMP in a satellite or ICBM could work on a timer, via GPS, or using an altimeter, says Pry, a nuclear strategist formerly with the CIA, who has a certificate in nuclear weapons design from the U.S. Air Force nuclear weapons lab. He says North Korea could even rig the warhead to detonate in the event that it was intercepted by our own missile defenses.

The consequences of such a detonation would be dire.

“The U.S. can sustain a population of 320 million people only because of modern technology,” said Pry. “An EMP that blacks-out the electric grid for a year would [decimate] the critical infrastructure necessary to support such a large population.”

In three days, the food supply in local grocery stores would be consumed and the 30-day national food supply in regional warehouses would begin to spoil, says Pry. In one year, he contends that up to 90 percent of the population could perish from starvation, disease, and societal collapse.

After generating gamma-rays that interact with air molecules in Earth’s stratosphere, a so-called fast pulse EMP field of tens of kilovolts would only last a few hundred nanoseconds.

But in the event of such an attack, aircraft electronics would be fried, as well as electronics in air traffic control towers, and navigation systems says Pry. “Airliners would crash killing many of the 500,000 people flying over North America at any given moment,” he said.

Pry says electro-mechanical systems which regulate the flow of gas through pipelines would spark; causing the gas to ignite and result in massive firestorms in cities and large forest fires.

There would be no water; no communications; and mass transportation would be paralyzed, says Pry. In seven days, he contends that reactors in U.S.’ nuclear power plants would essentially melt down, spreading radioactivity across most of the nation.

What could be done to ensure a quick restoration of the grid?

Some 2000 extra-high voltage (EHV) transformers make up the foundation of the U.S. grid, says Pry. But as he notes, since they each weigh hundreds of tons, they are extraordinarily hard to transport. Thus, if most are destroyed, there’s no quick fix.

So, how do we best protect against an EMP?

The U.S. should be prepared to also include limited surgical strikes to destroy North Korea’s ICBMs, says Pry. But he says the best, safest, and least provocative solution is to EMP-harden the electric grid and other critical infrastructures.

But not everyone agrees that North Korea poses a real EMP threat.

“There are legitimate concerns about EMP effects, but a non-tested system by a country with limited missile experience lowers the immediate threat,” James Clay Moltz, a professor of national security affairs at the Naval Postgraduate School in Monterey, Calif., told me.

The U.S. should work with China and South Korea on clear warnings against any such North Korean actions, says Moltz. That includes U.S. statements on the right to pre-empt or shoot down any suspected EMP weapons which, he says, would constitute nuclear attacks on the U.S.

“But predictions of mass U.S. casualties and demands for costly defenses against a [North Korean] EMP attack seem unjustified at this time,” said Moltz.

North Korea Nuclear EMP Attack: An Existential Threat

June 2, 2017

North Korea Nuclear EMP Attack: An Existential Threat, 38 North, June 2, 2017

(38 North is not a “click bait” site and tends to be fairly conservative in its analyses. Its conclusion that the threat of an EMP attack is real and that the consequences would be horrific should be credited. Although not mentioned, Iran is also a possible present or future source of an EMP attack. “Hardening the grid,” apparently our current focus, would help, but not very much.

Perhaps America should “test” the effects of EMP attacks by “experimenting” on North Korea and Iran simultaneously. In North Korea, the privileged few who are close to the Kim regime would be affected to a far greater extent than the peasants elsewhere. — DM)

In 2004, two Russian generals, both EMP experts, warned the EMP Commission that the design for Russia’s super-EMP warhead, capable of generating high intensity EMP fields of 200,000 volts per meter, was “accidentally” transferred to North Korea, and that due to “brain drain,” Russian scientists were in North Korea, helping with their missile and nuclear weapon programs. South Korean military intelligence told their press that Russian scientists are in North Korea helping develop an EMP nuclear weapon. In 2013, a Chinese military commentator stated North Korea has super-EMP nuclear weapons.[2]

***********************

Analysts like Jack Liu and Jeffrey Lewis are to be commended for their interest in educating the public about North Korea’s missile and nuclear programs and endeavoring to provide their readers with “informed analysis.” However, in a series of recent articles, both analysts have written off the possibility of a nuclear electromagnetic pulse (EMP) attack from North Korea as “unlikely” and “science fiction” because they believe the 10 to 20 kiloton nuclear weapons currently possessed by North Korea are incapable of making an effective EMP attack. This dismisses the consensus view of EMP experts who have advanced degrees in physics and electrical engineering along with several decades of experience in the field—with access to classified data throughout that time—and who have conducted EMP tests on a wide variety of electronic systems, beginning in 1963.

By way of background, the Commission to Assess the Threat to the United States from Electromagnetic Pulse Attack was established by Congress in 2001 to advise the Congress, the President, the Department of Defense and other departments and agencies of the US Government on the nuclear EMP threat to military systems and civilian critical infrastructures. The EMP Commission was re-established in 2015 with its charter broadened to include natural EMP from solar storms, all manmade EMP threats, cyber-attack, sabotage and Combined-Arms Cyber Warfare. The EMP Commission charter gives it access to all relevant classified and unclassified data and the power to levy analysis upon the Department of Defense.

In the interest of better informing 38 North readers about the EMP threat, we offer this commentary to correct errors of fact, analysis, and myths about EMP.

Primitive and “Super-EMP” Nuclear Weapons are Both EMP Threats

The EMP Commission finds that even primitive, low-yield nuclear weapons are such a significant EMP threat that rogue states, like North Korea, or terrorists may well prefer using a nuclear weapon for EMP attack instead of destroying a city.[1] In its 2004 report, the Commission cautioned: “Certain types of relatively low-yield nuclear weapons can be employed to generate potentially catastrophic EMP effects over wide geographic areas, and designs for variants of such weapons may have been illicitly trafficked for a quarter-century.”

In 2004, two Russian generals, both EMP experts, warned the EMP Commission that the design for Russia’s super-EMP warhead, capable of generating high intensity EMP fields of 200,000 volts per meter, was “accidentally” transferred to North Korea, and that due to “brain drain,” Russian scientists were in North Korea, helping with their missile and nuclear weapon programs. South Korean military intelligence told their press that Russian scientists are in North Korea helping develop an EMP nuclear weapon. In 2013, a Chinese military commentator stated North Korea has super-EMP nuclear weapons.[2]

Super-EMP weapons are low-yield and designed to produce not a big kinetic explosion, but rather a high level of gamma rays, which generate the high-frequency E1 EMP that is most damaging to the broadest range of electronics. North Korean nuclear tests—including the first in 2006, which was predicted to the EMP Commission two years in advance by the two Russian EMP experts—mostly have yields consistent with the size of a super-EMP weapon. The Russian generals’ accurate prediction of when the North would perform its first nuclear test, and the yield being consistent with a super-EMP weapon, indicates their warning about a North Korean super-EMP weapon should be taken very seriously.

EMP Threat from Satellites

While most analysts are fixated on when in the future North Korea will develop highly reliable intercontinental ballistic missiles, guidance systems, and reentry vehicles capable of striking a US city, the present threat from EMP is largely ignored. An EMP attack does not require an accurate guidance system because the area of effect, having a radius of hundreds or thousands of kilometers, is so large. No reentry vehicle is needed because the warhead is detonated at high-altitude, above the atmosphere. Missile reliability matters little because only one missile has to work to make an EMP attack.

For instance, North Korea could make an EMP attack against the United States by launching a short-range missile off a freighter or submarine or by lofting a warhead to 30 kilometers burst height by balloon. While such lower-altitude EMP attacks would not cover the whole US mainland, as would an attack at higher-altitude (300 kilometers), even a balloon-lofted warhead detonated at 30 kilometers altitude could blackout the Eastern Grid that supports most of the population and generates 75 percent of US electricity.

Moreover, an EMP attack could be made by a North Korean satellite. The design of an EMP or even a super-EMP weapon could be relatively small and lightweight, resembling the US W-79 Enhanced Radiation Warhead nuclear artillery shell of the 1980s, designed in the 1950s. Such a device could fit inside North Korea’s Kwangmyongsong-3 (KMS-3) and Kwangmyongsong-4 (KMS-4) satellites that presently orbit the Earth. The south polar trajectory of KMS-3 and KMS-4 evades US Ballistic Missile Early Warning Radars and National Missile Defenses, resembling a Russian secret weapon developed during the Cold War, called the Fractional Orbital Bombardment System (FOBS) that would have used a nuclear-armed satellite to make a surprise EMP attack on the United States.[3]

Kim Jong Un has threatened to reduce the United States to “ashes” with “nuclear thunderbolts” and threatened to retaliate for US diplomatic and military pressure by “ordering officials and scientists to complete preparations for a satellite launch as soon as possible” amid “the enemies’ harsh sanctions and moves to stifle” the North.[4]

Addressing Misinformation

Recent assessments by Jeffrey Lewis and Jack Liu regarding North Korea’s EMP capabilities have some fundamental flaws.[5]

For starters, in his article, Jeffrey Lewis claimed that “just one string of street lights failed in Honolulu” during the 1962 Starfish Prime high-altitude nuclear test, and that this is proof of EMP’s harmlessness.[6] In fact, the EMP knocked out 36 strings of street lights, caused a telecommunications microwave relay station to fail, burned out HF (high frequency) radio links (used for long-distance communications), set off burglar alarms, and caused other damage. The Hawaiian Islands also did not experience a catastrophic protracted blackout because they were on the far edge of the EMP field contour, where effects are weakest; are surrounded by an ocean, which mitigates EMP effects; and were still in an age dominated by vacuum tube electronics. In addition, the slow pulse (E3) component of the EMP waveform only couples effectively to very long electric power transmission lines present on large continents, but were in short supply in Hawaii.

Starfish Prime was not the only test of this kind. Russia, in 1961-62, also conducted a series of high-altitude nuclear bursts to test EMP effects over Kazakhstan, an industrialized area nearly as large as Western Europe.[7] That test damaged the Kazakh electric grid.[8] Moreover, modern electronics, in part because they are designed to operate at much lower voltages, are much more vulnerable to EMP than the electronics of 1962 exposed to Starfish Prime and the Kazakh nuclear tests. A similar EMP event over the US today would be an existential threat.[9]

In his article, Lewis also suggested that vehicle transportation would continue after an EMP event based on the fact that only 6 of 55 vehicles were shut down by a single simulated EMP test on vehicles.[10] However, the EMP test protocol limited testing vehicles only to upset, not to damage, because the EMP Commission could not afford to repair damaged cars. Even with this limitation, one vehicle was still damaged, indicating that at least 2 percent of vehicles were severely affected by EMP damage. Over 50 years of EMP testing indicates that full field damage to vehicles would probably be much higher than 2 percent. Modern vehicles are even more susceptible to EMP attack because of their much larger complement of electronics than present in the vehicles tested by the Commission more than a decade ago. Furthermore, vehicles cannot run without fuel and gas stations cannot operate without electricity. Gas pumps could also be damaged in an EMP attack.

In an article by Jack Liu, he asserts in a footnote that because EMP from atmospheric nuclear tests in Nevada did not blackout Las Vegas, therefore EMP is no threat. However, the nuclear tests he describes were all endo-atmospheric tests that do not generate appreciable EMP fields beyond a range of about 5 miles. The high-altitude EMP (HEMP) threat of interest requires exo-atmospheric detonation, at 30 kilometers altitude or above, and produces EMP out to ranges of hundreds to thousands of miles.

Liu also miscalculates that “a 20-kiloton bomb detonated at optimum height would have a maximum EMP damage distance of 20 kilometers” in part, because he assumes “15,000 volts/meter or higher” in the E1 EMP component is necessary for damage. This figure is an extreme overestimation of system damage field thresholds. Damage and upset to electronic systems will happen from E1 EMP field strengths far below Liu’s “15,000 volts/meter or higher.” A one meter wire connected to a semiconductor device, such as a mouse cord or interconnection cable, would place hundreds to thousands of volts on microelectronic devices out to ranges of hundreds of miles for low-yield devices. Based on our experience with many EMP tests, semiconductor junctions operate at a few volts, and will experience breakdown at a few volts over their operating point, allowing their power supply to destroy exposed junctions.

Furthermore, Liu ignores system upset as a vulnerability. Digital electronics can be upset by extraneous pulses of a few volts. For unmanned control systems present within the electric power grid, long-haul communication repeater stations, and gas pipelines, an electronic upset is tantamount to permanent damage. Temporary upset of electronics can also have catastrophic consequences for military operations. No electronics should be considered invulnerable to EMP unless hardened or tested to certify survivability. Some highly-critical unprotected electronics have been upset or damaged in simulated EMP tests, not at “15,000 volts/meter or higher,” but at threat levels far below 1,000 volts/meter.

Therefore, even for a low-yield 10-20 kiloton weapon, the EMP field should be considered dangerous for unprotected US systems. The EMP Commission 2004 Report warned against the US military’s increasing use of commercial-off-the-shelf-technology that is not protected against EMP: “Our increasing dependence on advanced electronics systems results in the potential for an increased EMP vulnerability of our technologically advanced forces, and if unaddressed makes EMP employment by an adversary an attractive asymmetric option.”[11] The North Korean missile test on April 29, which apparently detonated at an altitude of 72 kilometers, the optimum height-of-burst for EMP attack by a 10 KT warhead, would create a potentially damaging EMP field spanning an estimated 930 kilometer radius [kilometers radius = 110 (kilometers burst height to the 0.5 Power)], not Liu’s miscalculated 20 kilometer radius.

US Vulnerabilities to EMP

When assessing the potential vulnerability of US military forces and civilian critical infrastructures to EMP, it is necessary to be mindful of the complex interdependencies of these highly-networked systems, because EMP upset and damage of a very small fraction of the total system can cause total system failure.[12]

Real world failures of electric grids from various causes indicate that the Congressional EMP Commission, US Department of Defense, US Federal Energy Regulatory Commission (FERC), US Department of Homeland Security, and US Defense Threat Reduction Agency are right that a nuclear EMP attack would have catastrophic consequences. Significant and highly-disruptive blackouts have been caused by single-point failures cascading into system-wide failures, originating from damage comprising far less than 1 percent of the total system.[13]

In contrast to blackouts caused by single-point or small-scale failures, a nuclear EMP attack would inflict massive widespread damage to the electric grid, causing millions of failure points. With few exceptions, the US national electric grid is unhardened and untested against nuclear EMP attack. In the event of a nuclear EMP attack on the United States, a widespread protracted blackout is inevitable. This common sense assessment is also supported by the nation’s best computer modeling.[14]

Thus, even if North Korea only has primitive, low-yield nuclear weapons, and if other states or terrorists acquire one or a few such weapons as well as the capability to detonate them at an altitude of 30 kilometers or higher over the United States. As, the EMP Commission warned over a decade ago in its 2004 Report, “the damage level could be sufficient to be catastrophic to the Nation, and our current vulnerability invites attack.”

[7] High-altitude EMP (HEMP), the phenomenon under discussion, results from the detonation of a nuclear weapon at high-altitude, 30 kilometers or higher. All nuclear weapons, even a primitive Hiroshima-type A-bomb, can produce levels of HEMP damaging to modern electronics over large geographic regions.

[8] According to Electric Infrastructure Security Council, Report: USSR Nuclear EMP Upper Atmosphere Kazakhstan Test 184, (www.eiscouncil.org/APP_Data/upload/a4ce4b06-1a77-44d-83eb-842bb2a56fc6.pdf), citing research by Oak Ridge National Laboratory, a comparable EMP event over the U.S. today “would likely damage about 365 large transformers in the U.S. power grid, leaving about 40 percent of the U.S. population without electrical power for 4 to 10 years.”

[13]For example, the Great Northeast Blackout of 2003—that put 50 million people in the dark for a day, contributed to at least 11 deaths, and cost an estimated $6 billion—originated from a single failure point when a powerline contacted a tree branch, damaging less than 0.0000001 (0.00001%) of the total system. The New York City Blackout of 1977, which resulted in the arrest of 4,500 looters and injury of 550 police officers, was caused by a lightning strike on a substation that tripped two circuit breakers. India’s nationwide blackout of 2012—the largest blackout in history, effecting 670 million people, 9% of the world population—was caused by overload of a single high-voltage powerline.

[14]Modeling by the US FERC reportedly assesses that a terrorist attack that destroys just 9 of 2,000 EHV transformers–merely 0.0045 (0.45%) of all EHV transformers in the US national electric grid–would be catastrophic damage, causing a protracted nationwide blackout. Modeling by the Congressional EMP Commission assesses that a terrorist nuclear EMP attack, using a primitive 10-kiloton nuclear weapon, could destroy dozens of EHV transformers, thousands of SCADAS and electronic systems, causing catastrophic collapse and protracted blackout of the US Eastern Grid, putting at risk the lives of millions.
