Kang Nam 1 Mystery Trip

Thursday, July 2nd, 2009

kang-nam1.jpg

Underway for two weeks now, North Korea’s unim­pos­ing mer­chant ship Kang Nam 1 con­tin­ues her mys­tery trip through the South China Sea at a sedate 10 knots. I expect this is for bet­ter fuel econ­omy but not because her cap­tain or Kim Jong Il want to be green. According to the Associated Press, anony­mous U.S. intel­li­gence sources said on Tuesday that she altered course back north and is now about 250 miles south of Hong Kong. 

Kang Nam 1 is believed by some Western author­i­ties to pos­si­bly be bound, or at least orig­i­nally have been bound, for Myanmar with an export ship­ment of con­ven­tional arms — maybe mor­tars, or per­haps mis­sile parts. Herein lies the rub. After Kim’s second-​​ever atom bomb test in May, the UN passed a res­o­lu­tion, bind­ing on all mem­ber states, which gives the appear­ance of estab­lish­ing a quar­an­tine against mar­itime trans­port of arms or nuclear-​​related items for sale by the DPRK. But the res­o­lu­tion lacks teeth. If Kang Nam 1 can some­how make it to a friendly des­ti­na­tion (Myanmar, or back to her start­ing point of Nampo, or some­where else) with­out refu­el­ing in a third-​​party pro-​​UN port such as Singapore, noth­ing stands in her way. 

A U.S. Navy spokesman indi­cated a lack of good data on both the ship’s fuel mileage and the capac­ity of her fuel tanks, though pre­sum­ably experts can make basic esti­mates. It’s unclear to me from pub­lic accounts whether Kang Nam 1 was pro­vided before depar­ture with extra fuel, a large cache of which could sim­ply take the form of fuel drums crammed into some of her holds. It’s also unclear what might hap­pen if she’s met in inter­na­tional waters, in rea­son­ably calm weather, by another North Korean-​​flagged ship, civil­ian or naval, that could con­duct a prim­i­tive but effec­tive under­way replen­ish­ment. Kang Nam 1 has been trailed from beyond the hori­zon by a U.S. Navy destroyer, but the U.S. is pro­ceed­ing very cau­tiously about mak­ing any sort of demand to board and inspect the cargo. 

David Sanger of the New York Times sug­gests that Kang Nam 1’s voy­age might be a provo­ca­tion designed to embar­rass America. I’m inclined to agree. Sean McGuire of Reuters hints that increas­ing leaks of out­side real­ity into North Korea could under­mine the cred­i­bil­ity of Kim’s stri­dent anti-U.S. rhetoric among his own peo­ple, weak­en­ing his power. To dra­mat­i­cally innoc­u­late the pop­u­lace against such “exter­nal dis­in­for­ma­tion” would give Kim ample motive to have set up Kang Nam 1 as bait in an elab­o­rate pro­pa­ganda trap.

How M.A.D. is Kim Jong Il?

Tuesday, June 23rd, 2009

nork-teapo.jpg

A June 18 AP story reports that the Democratic People’s Republic of Korea (North Korea) plans to launch a Taepodong-​​2 bal­lis­tic mis­sile toward Hawaii in early July — pos­si­ble on July 4. 

The mis­sile has a max­i­mum range of 4,000 miles, and so will land at least 500 miles short of Hawaii. Coming so soon after Kim Jong Il’s second-​​ever nuclear test on May 25, one won­ders what the iso­lated and eccen­tric Communist dic­ta­tor is really up to. 

Some ana­lysts have said that the nuclear test, in defi­ance of inter­na­tional pres­sures, was intended mainly for its effect on domes­tic DPRK pol­i­tics. Kim recently annointed his younger son, little-​​known Kim Jong Un, as his suc­ces­sor, in what pun­dits describe as a pecu­liar North Korean-​​style Communist dynasty. If found­ing father of the North Korean state, Kim Il Sung, can be labeled Kim I (“Kim the First”), that makes Kim Jong Il become Kim II. His sec­ond son, now ele­vated to crown prince, would then become Kim III when ail­ing Kim II dies, which might be soon. As one sign of the rais­ing of Kim Jong Un within North Korean pol­i­tics and soci­ety (the two are closely related), he was recently granted a spe­cial name, “Brilliant Comrade,” sim­i­lar in tone to his father’s “Dear Leader.“ 

In under­stand­ing Kim II’s real motives behind these dra­matic weapon tests, we need to remem­ber that he wants what he wants, not what we think he wants or ought to want. To fail to focus on the infa­mously enig­matic Kim solely from his own per­spec­tive is to com­mit “mir­ror­ing” — always a mis­take in mod­ern geopolitics. 

Much of the time, a dictator’s top pri­or­ity is to main­tain his/​her own power. In the case of an actual or de facto monarch, there is also a pow­er­ful drive to keep the throne within the fam­ily, for a dynasty that goes on for many gen­er­a­tions. If Kim Jong Il is act­ing now like King Kim II, which he has been for years to some degree, he may be think­ing now as King Kim II as well. The self-​​imposed iso­la­tion of his well defended coun­try would be one ele­ment of the throne’s self-​​perpetuation. Establishing a clear heir to the throne would be another. 

A very impor­tant third would be the need for for­eign exchange monies with which to feed and clothe his peo­ple — and with which to keep his mil­i­tary happy enough to main­tain him and his off­spring in power for­ever. A big inter­na­tional con­cern is that Kim II might sell a work­ing, weaponized nuke to ter­ror­ists, per­haps for the “black mar­ket going rate” of $100 mil­lion. In these monar­chi­cal terms, his goal in doing so would be to refill the royal cof­fers for a while. 

If the sec­ond under­ground nuke test was a weird form of fire­works cel­e­bra­tion for Brilliant Comrade’s annoint­ment, the impend­ing ICBM test might be a ges­ture demand­ing inter­na­tional respect for this Kim Dynasty, com­bined with what could well be a ges­ture intended as a ran­som note in a case of global nuclear black­mail — more prop­erly, of grandiose extortion. 

Why wouldn’t China offer to buy out any nukes that Kim II might move close to sell­ing, per­haps at a price of two or ten times the going rate for the ilk of al Qaeda? Beijing could sim­ply pro­vide to Kim Jong Il, as “for­eign aid,” a few brief­cases full of a tiny frac­tion of the U.S. Treasury bonds they own. This would be a bar­gain, com­pared to the ben­e­fits to ultra-​​ambitious and auto­cratic China of main­tain­ing peace and sta­bil­ity in Asia and pre­vent­ing the global desta­bi­liza­tion that a ter­ror­ist nuke blast would surely cre­ate. After all, China con­tin­ues to show some dis­re­gard for human rights, so why should it care overly much for the wel­fare of Kim II’s sub­jects? Foreign aid like this would actu­ally or at least poten­tially improve the wel­fare of those subjects.

Epic Fail: North Korean Bottle Rocket Assumes Underwater Trajectory

Sunday, April 5th, 2009

kim jong il.jpgNorthern Command reports:

North American Aerospace Defense Command and U.S. Northern Command offi­cials acknowl­edged today that North Korea launched a Taepo Dong 2 mis­sile at 10:30 p.m. EDT Saturday which passed over the Sea of Japan/​East Sea and the nation of Japan.
Stage one of the mis­sile fell into the Sea of Japan/​East Sea. The remain­ing stages along with the pay­load itself landed in the Pacific Ocean. 

Sounds like the sec­ond stage never sep­a­rated –or ignited– giv­ing the birdie about as much thrust as a slab of gran­ite. Hence the splish-​​splash just east of Japan. No doubt if we were the shoot­ers, we’d call it a cat­a­strophic suc­cess. Bureaucracy!
I’m sure the only peo­ple more dis­ap­pointed than the Nork regime are our friendly neigh­bor­hood MDA suits, who were count­ing on the launch to cal­i­brate their radars and to remain rel­e­vant.

Real Korea Worry: Chem-​​Bio

Tuesday, October 17th, 2006

North Korea’s newly-​​tested nuke is bad news, for sure. But the big­ger worry, says Popular Mechanics is the “huge arse­nal of mass casu­alty weapons” that Kim & Co. have been assem­bling for 45 years: bio­log­i­cal and chem­i­cal arms.
vstory.us.clean.ap.jpg

While it would be fool­ish not to be gravely con­cerned about North Korea’s pur­ported devel­op­ment of an offen­sive nuclear capa­bil­ity, the actual threat for the fore­see­able future is, arguably, min­i­mal. North Korea’s thread­bare econ­omy (it has a GDP of $40 bil­lion — com­pare that to California’s gross state prod­uct on $1.55 tril­lion per year) is inca­pable of main­tain­ing an effec­tive nuclear weapons pro­gram. Its nuclear sci­ence is at best sec­ond rate and, cer­tainly, is sec­ond hand.
In con­trast, as one North Korea expert explained to me, CBW is mass destruc­tion on the cheap. “Biological and chem­i­cal weapons are very inex­pen­sive, many, many times cheaper than nuclear.” Another expert gave this grim assess­ment: “The use of anthrax is a dis­tinct pos­si­bil­ity for this nation [North Korea]…“
The con­sen­sus among weapons inspec­tors, intel­li­gence ana­lysts, aca­d­e­mics and oth­ers I have inter­viewed­which is backed up by the avail­able open source material-​​is that North Korea has devel­oped anthrax, plague and bot­u­lism toxin as weapons and has exten­sively researched at least six other germs includ­ing small­pox and typhoid. It is also believed to have 5,000 tons or more of mus­tard gas, sarin nerve agent and phos­gene (a chok­ing gas). The Center for Nonproliferation Studies says North Korea ranks “amongst the largest pos­ses­sors of chem­i­cal weaponry in the world.” South Korea’s mil­i­tary esti­mates half of North’s long-​​range mis­siles and 30 per­cent of its artillery are CBW capa­ble…
Yet the West’s myopic obses­sion with North Korea’s nuclear efforts has allowed this far more real and equally lethal threat to escape into the shad­ows: a WMD pro­gram, backed by in excess of 13,000 spe­cially trained troops, capa­ble of dev­as­tat­ing its south­ern neigh­bor, attack­ing U.S. troops in Asia and dis­rupt­ing the regional econ­omy in ways that could see the U.S. and other west­ern nations plunged into cri­sis.
Yes, the new [United Nations] res­o­lu­tion 1718(2006) includes a ref­er­ence to bio­log­i­cal and chem­i­cal weapons of mass destruc­tion, but only as an after­thought, and the res­o­lu­tion exists only because of the nukes and their per­ceived threat. Unfortunately, in this case, as with oth­ers, the world is overly focused on a poten­tial retina-​​searing nuclear det­o­na­tion, with­out prop­erly appre­ci­at­ing the very clear-​​and-​​present CBW killer that exists just a vir­tual button’s push away from Kim Jong Il’s per­fectly man­i­cured fingernails.

If the whole thing sounds a lit­tle hys­ter­i­cal to you, chem-​​bio guru Jason Sigger says: get real. The story is “100 per­cent right in regards to N. Korea. And you can extend that argu­ment to China, Iran, Syria, Israel, Pakistan, and India, and poten­tially in the near future (because of Iran), Egypt, Saudi Arabia, and others.”

Seriously, I see this all the time in the “com­bat­ing WMD” com­mu­nity. The arms con­trol and coun­ter­pro­lif­er­a­tion peo­ple talk “WMD” but the sub­text is “nuke.” Even the major­ity of the con­se­quence man­age­ment tasks are now “dirty bomb” or “impro­vised nuclear device” sce­nar­ios… [the] men­tal­ity is [that] nukes are the only thing that can dras­ti­cally affect US mil­i­tary power in any region of the world.

But there are other threats, too.

Nork Test: No Big Whoop?

Friday, October 13th, 2006

“There is no ques­tion that the polit­i­cal and secu­rity impli­ca­tions of the [recent North Korean nuclear] test are huge and almost entirely neg­a­tive,” writes Ivan Oelrich, over at the Strategic Security Blog. “The tech­ni­cal sig­nif­i­cance of the test is some­what less than meets the eye.“
puppet3.jpg

[A week ago,] the out­side world knew that the North Koreans had plu­to­nium avail­able from fuel rods that had been removed from the reac­tor at Yongbyon. We knew that at least some of the plu­to­nium had been sep­a­rated out of the fuel rods and, since sep­a­ra­tion is a fairly straight­for­ward process, it was a fair assump­tion that most or all of the plu­to­nium had been sep­a­rated. So we knew about their plu­to­nium sup­ply (and the test tells us noth­ing more about that), but another key ques­tion remained: Could they fash­ion the plu­to­nium into a bomb?
…Before the test, we did not know whether the North Koreans could build an implo­sion bomb or not. Had the test been suc­cess­ful, we would now know that they could, although we would still not know how close they were to a use­able weapon; their test device might have weighed tons and been a once off, rigged up, lab­o­ra­tory exper­i­ment. But the test was not suc­cess­ful, so we still dont know whether the North Koreans can build a work­able implo­sion bomb. Presumably the North Koreans learned some­thing from the test so the prob­a­bil­ity of the next test being suc­cess­ful is some­what higher than the prob­a­bil­ity that the first test would have been suc­cess­ful. This is not much of dif­fer­ence, leav­ing us in pretty much the same posi­tion we were in before the test…
Why might the test have failed? An implo­sion bomb uses con­ven­tional high explo­sives to com­press plu­to­nium until it becomes crit­i­cal, that is, it will sus­tain a run-​​away chain reac­tion. The pres­sure from the con­ven­tional explo­sives has to be care­fully con­trolled, for exam­ple, it must be sym­met­ric or else it is like squeez­ing a ball of putty: pres­sure on one side doesnt com­press the plu­to­nium, it just squirts it out the other side. The most likely rea­son for the fail­ure is some prob­lem with the com­pres­sion and there is any num­ber of rea­sons why the com­pres­sion might not be ade­quate. If the test were care­fully instru­mented (which is not nec­es­sar­ily the case), the North Koreans should be able to nar­row down the cause, which will give them a much improved chance for suc­cess with their next test.

UPDATE 10/​14/​06 11:20 AM: “Initial envi­ron­men­tal sam­ples col­lected by a U.S. mil­i­tary air­craft detected signs of radi­a­tion over the Sea of Japan, pos­si­bly con­firm­ing North Korea’s nuclear test,” the Washington Post reports.
UPDATE 10/​15/​06 7:06 PM: “The propo­si­tion that the appar­ently low yield of the test is a fail­ure is not self evi­dent,” says Defense Tech pal John Pike, point­ing to this Weekly Standard piece. After all, Pike notes, the yield on the American B61 nuke can range any­where from a third of a kilo­ton to more than 350 kt.
UPDATE 10/​15/​06 7:23 PM: No excerpt will do jus­tice to this epic retelling of North Korea 50-​​year quest for the Bomb. So just go and read the whole thing.

Big War Machines Pushed for Korea Fight

Tuesday, October 10th, 2006

There are still a whole heap of unknowns, in the wake of North Korea’s nuclear test. But here’s some­thing you can take to the bank: every admi­ral, every Air Force gen­eral, and every Congresscritter with a big, hulk­ing, weapon sys­tem is going to crow about how his gazillion-​​dollar machine is the key to fix­ing the Korean prob­lem.
ddxs.jpgEven before Kim’s October sur­prise, Air Force offi­cials like Maj. Gen. Charles Dunlap Jr. were rail­ing against “boots-​​on-​​the-​​ground zealots” and “neo-​​Luddites” who “quot[e] coun­terin­sur­gency man­u­als from the horse cav­alry era.” Instead, Dunlap insisted, we should be pour­ing money into “air power our most effec­tive national secu­rity com­po­nent.“
With the Army lob­by­ing for a big­ger chunk of the Pentagon bud­get, expect the vol­ume on these Air Force and Navy-​​first screams to be turned up sev­eral notches in the months to come. Wanna shell the Norks’ nuke facil­i­ties from way out in the sea? Then you need a big ol’ DD(X) destroyer to do the shelling. Attacking from the air? For that, you just have to have a next-​​generation, long-​​range bomber. Oh, and a whole bunch of conventionally-​​armed Trident bal­lis­tic mis­siles, too. And so on…
Of course, “American air units in South Korea, Japan, and the United States, plus the US Third and Seventh Fleets, are avail­able to block­ade North Korea and strike at tar­gets of oppor­tu­nity” today, Arms and Influence notes.

However, it remains to be seen what oppor­tu­ni­ties for puni­tive and dis­arm­ing strikes exist, or what the North Korean response would be… The facil­i­ties are too dis­persed, often in the worst kind of geog­ra­phy for pre­ci­sion bomb­ing, moun­tain­ous ter­rain. Even if the US were able to hit every North Korean nuclear and pro­duc­tion facil­ity, the obvi­ous ques­tion would be, What’s next?
We can pre­dict at least one imme­di­ate con­se­quence: a North Korean attack on South Korea. Whether the North Korean army tries to seize con­trol of the South, or merely retal­i­ate with con­ven­tional and chem­i­cal artillery attacks on Seoul and other pop­u­la­tion cen­ters, the US would need ground forces to take the next step: elim­i­nate the North Korean gov­ern­ment. Even with its nuclear fangs removed, the North Korean gov­ern­ment would remain a men­ace to the South, and per­haps would have rea­sons to try for one last gam­ble to end the decades-​​long stale­mate on the Korean penin­sula…
The United States has an impres­sive array of car­rier bat­tle groups, attack sub­marines, tac­ti­cal air assets, and strate­gic bombers that it can hurl at North Korea. However, the last sev­eral years have taught Americans an impor­tant les­son about war­fare: your own strength mat­ters far less than what you actu­ally do with it.

UPDATE 4:39 PM: The Herald-​​Tribune has a good run­down of just how piss-​​poor the Norks’ con­ven­tional forces really are.

The mil­i­tary in North Korea is by far the largest con­sumer of the coun­trys scarce resources. But even so, its com­bat jet pilots get only about two hours of fly­ing time a month, its sol­diers some­times have to grow their own food, and much of its equip­ment is old and out­classed by that of its neigh­bors. According to South Korean and Western experts, if a con­ven­tional war breaks out on the Korean Peninsula, the best the North Korean mil­i­tary could man­age would be to fight to a bloody stale­mate.
It is the deep inse­cu­rity born of these short­com­ings, the experts say, and not any desire to grab atten­tion or gain lever­age, that drove President Kim Jong-​​ils deci­sion to defy inter­na­tional warn­ings and declare this week that his coun­try had tested a nuclear weapon.

Nork Fallout: Asia Arms Race?

Tuesday, October 10th, 2006

So here we are, 36 hours later, and every­body is still talk­ing about North Korea’s nuclear test. But despite all the ner­vous chat­ter, not much has changed, at least in the short term. (Down the road is a much dif­fer­ent story.)
China-japan.jpgCondemnations of the Norths brazen act aside, China is no more will­ing now than they were last week to risk a col­lapsed regime on their bor­der — it almost assures a flood of refugees and a US mil­i­tary ally shar­ing a bor­der with China. The USs options are sim­i­larly lim­ited even if we know where all their nuclear sites are, its unlikely wed be will­ing to bet that the unpre­dictable Kim regime wouldnt retal­i­ate against Seoul. That leaves us to do what weve got­ten good at with North Korea: issu­ing a strong con­dem­na­tion and then hop­ing that CNN switches back over to cov­er­age of Jon Benet Ramsey.
The only big poten­tial short term impli­ca­tion is if the inter­na­tional com­mu­nity demon­strates that this test was a fake, or a dud. Then the North will be forced to up the ante to com­pen­sate for the embar­rass­ment (just as the nuke test was to com­pen­sate for the humil­i­at­ing fail­ure of the July long range mis­sile test).
The real impact of the Kim’s nuclear trial is in the long term. That’s when things have the poten­tial to get extremely scary. Not only do you get the pos­si­bil­ity of the Norks throw­ing a nuclear yard sale for ter­ror­ists. But for Japans new prime min­is­ter, Shinzo Abe, it ener­gizes his push to strengthen Japans secu­rity capac­ity like noth­ing else could have. Abe had already appointed a num­ber of fel­low con­ser­v­a­tives in Foreign Ministry and Defense posi­tions in the cab­i­net, hes declared his intent to mod­ify the con­sti­tu­tions lim­i­ta­tions on Japanese mil­i­tary capac­ity, and he mooted the pos­si­bil­ity for a Japanese pre-​​emptive strike against North Korea in the after­math of the July mis­sile tests. The paci­fist nature of Japans con­sti­tu­tion is rea­son­ably well-​​ingrained in Japanese polit­i­cal cul­ture, and he would have met a lot of resis­tance in these moves. That resis­tance will be dras­ti­cally weak­ened by the North Korean test. From there, its a short log­i­cal step to the usual sce­nar­ios of a Sino-​​Japanese arms race in East Asia. And there’s only one word for how that sce­nario plays out: Gulp.

Korea Nuke: a ‘Fizzle?’

Tuesday, October 10th, 2006

In the days ahead, we’ll hear all kinds of rea­sons why the Nork nuke test was so suck­tas­tic. (Suitcase bomb, any­one?) Dicky Destiny — a.k.a. Dr. George Smith, of GlobalSecurity​.org — has a plau­si­ble early can­di­date: “‘fiz­zle yield’; that is, the small­est nuclear yield [a] par­tic­u­lar device could pro­vide.“
vc68a.4a.jpg

“… [T]here is a moment when the [bomb’s] fis­sile mate­r­ial becomes crit­i­cal (pro­jec­tile still on its way to its des­ti­na­tion [in a gun-​​type weapon], or only a small part of the mate­r­ial com­pressed [in an implosion-​​type weapon]) and the time it reaches its intended state. During this inter­val, the degree of super­crit­i­cal­ity is build­ing up toward its final value. If a chain reac­tion were ini­ti­ated by neu­trons from some other source dur­ing this period, the yield real­ized would be much smaller –pos­si­bly a great deal smaller — than the nom­i­nal yield. Such an event is referred to as preini­ti­a­tion (or some­times pre­det­o­na­tion).
… “If the [bomb’s] assem­bly veloc­i­ties (of the pro­jec­tile or mate­r­ial dri­ven by an implo­sion) are quite low, the ear­li­est pos­si­ble preini­ti­a­tion could lead to an energy release (equiv­a­lent weight of high explo­sive) not many times larger than the weight of the device.“
Other parts of the dis­cus­sion on bomb design obsta­cles, also pre­sented at the sem­i­nar, indi­cated that yields lower by a fac­tor of ten in crude designs can be indica­tive of fiz­zles. What infor­ma­tion has been pub­lished on the North Korean test falls into this range.
Summarized, there are cer­tain num­ber of things that can go wrong when fir­ing your first atomic bomb, par­tic­u­larly when using a crude design. And one might expect to see them from a weird and crazy her­mit nation, like North Korea, endeav­or­ing to enter the nuclear club.

NORK Nuclear Test: It’s A Dud (Updated)

Monday, October 9th, 2006

HA HA HA HA.
I — Jeffrey Lewis, cross­post­ing from Arms Control Wonklove the US Geological Survey.
They’ve pub­lished lat/​long (41.294 N, 129.134 E) and Mb esti­mates (4.2) for the North Korean test.
There is lots of data float­ing around: The CTBTO called it 4.0; The South Koreans report 3.58–3.7.
crap.gifYou’re think­ing, 3.6, 4.2, in that neigh­bor­hood. Seismic scales, like the Richter, are log­a­rith­mic, so that neigh­bor­hood can be pretty big.
But even at 4.2, the test was prob­a­blya dud.
Estimating the yield is tricky busi­ness, because it depends on the geol­ogy of the test site. The South Koreans called the yield half a kilo­ton (550 tons), which is more or less — a fac­tor of two — con­sis­tent with the rela­tion­ship for tests in that yield range at the Soviet Shagan test site:
Mb = 4.262 + .973LogW
Where Mb is the mag­ni­tude of the body wave, and W is the yield.
3.58–3.7 gives you a cou­ple hun­dred tons (not kilo­tons), which is pretty close in this busi­ness unless you’re really math pos­i­tive. The same equa­tion, given the US esti­mate of 4.2, yields (pun intended) around a kilo­ton.
A plu­to­nium device should pro­duce a yield in the range of the 20 kilo­tons, like the one we dropped on Nagasaki. No one has ever dud­ded their first test of a sim­ple fis­sion device. North Korean nuclear sci­en­tists are now offi­cially the worst ever.
Of course, I want to see what the US IC says. If/​when the test vents, we could have some radionu­clide data — maybe in the next 72 hours or so.
But, from the ini­tial data, I’d say some­one with no work­able nuclear weapons (Kim Jong Il, I am look­ing at you) should be crap­ping his pants right now.
First the mis­sile, then the bomb. Got any­thing else you wanna try out there, chief?
Jeffrey Lewis, cross-​​posted at Arms Control Wonk​.com
UPDATE 10/​10/​06 1:14 AM: Noah here. Looks like the LA and NY Times have both picked up (sorta) on what the good Wonk was sayin’.

Throughout his­tory, the first det­o­na­tions of aspir­ing nuclear pow­ers have tended to pack the destruc­tive power of 10,000 to 60,000 tons 10 to 60 kilo­tons of con­ven­tional high explo­sives.
But the strength of the North Korean test appears to have been a small frac­tion of that: around a kilo­ton or less, accord­ing to sci­en­tists mon­i­tor­ing the global arrays of seis­mome­ters that detect faint trem­bles in the earth from dis­tant blasts…
Philip E. Coyle III, a for­mer direc­tor of weapons test­ing at the Pentagon and for­mer direc­tor of nuclear test­ing for the Lawrence Livermore National Laboratory, a weapons design cen­ter in California, said the small size of the test sig­naled the pos­si­bil­ity of what might be described as a par­tial suc­cess or a par­tial fail­ure.
As first tests go, this is smaller and less suc­cess­ful than those of the other nuclear pow­ers, he said.
Perhaps the North Koreans wanted to keep it small, he added. But if it turns out to be a kilo­ton or less, Dr. Coyle said, that would sug­gest that they hoped for more than that and didnt get it.

UPDATE 10/​10/​06 8:45 AM: Rumor alert! Stratfor is pretty sure that the Nork nuke — “about one-​​fortieth of the Nagasaki blast” — was a dud, too. But, just to be on the safe side, the intel ser­vice offers up “three pos­si­ble expla­na­tions for the appar­ently small yield: the North Koreans delib­er­ately det­o­nated a very small device, they tested a larger device but it failed to exe­cute prop­erly, or the explo­sion was not caused by an atomic device.”

Possibly the North Koreans wanted to show that they had the tech­nol­ogy but did not want to appear too threat­en­ing, so they min­i­mized the size. Or they could be demon­strat­ing the abil­ity to use lower-​​yield nuclear mines or artillery shells that would pro­tect North Korea by block­ing strate­gic passes into the coun­try, and would pos­si­bly threaten Seoul but would not pose a sig­nif­i­cant threat else­where. Also, the water table is high in the area of the blast; maybe they were being care­ful not to break into the aquifer.
These are all good rea­sons, but the coun­ter­ar­gu­ment is that if you are going to go nuclear, go nuclear. North Korea does not have a press­ing need — or his­tory — of being sub­tle, so a small blast doesn’t fit in with its plan…
What if the North Koreans didn’t go nuclear, but det­o­nated a large chem­i­cal explo­sive in an under­ground cham­ber? It would take a lot of explo­sive to yield that result, but it is not impos­si­ble. A chem­i­cal explo­sion would have a dif­fer­ent seis­mic sig­na­ture than a nuclear one, and there­fore geol­o­gists should have already dis­counted this the­ory; but the analy­sis is going to take up to two days, accord­ing to the White House. It is cer­tainly not beyond the North Koreans to fake a nuclear explo­sion, and there have been some big explo­sions in North Korea that have been mis­taken, for a short period of time, for some­thing nuclear. But there is no evi­dence, beyond our spec­u­la­tion, for this theory. 

UPDATE 10/​10/​06 8:51 AM: Interesting counter-​​argument from Trent Telenko in the com­ments. Since North Korea has “had the com­plete design spec­i­fi­ca­tions for a Chinese missile-​​ready nuclear war­head of the plu­to­nium implo­sion type for years,” thanks to the A.Q. Khan net­work, this dud may be more dan­ger­ous than it seems.

Missile Flop: Norks in Tight Spot

Thursday, July 6th, 2006

The New York Times and oth­ers are fram­ing North Korea’s busted mis­sile test as a major prob­lem for the U.S. — espe­cially with China and Russia refus­ing to take a hard line against Pyongyang, for now. “President Bush and his national secu­rity advis­ers found them­selves on Wednesday fac­ing what one close aide described as an array of ‘famil­iar bad choices,’” the Times said.
143ADA.jpgThat seems a lit­tle upside-​​down to me. Isn’t Kim Jong-​​il the one with the bad choices here, now that his supposedly-​​intercontinental mis­sile flopped less than a minute into its flight?
“Over these past few years, [Kim] has adroitly played his oth­er­wise mis­er­able hand because of two cards that every­one believes he hold­snu­clear weapons and long-​​range mis­siles. Yesterday’s dud raises the pos­si­bil­ity that the mis­sile card’s a bluff, that there may be (as Gertrude Stein once said of Oakland) ‘no there there,’” says Slate’s Fred Kaplan.
“Seems to me their ICBM [inter­con­ti­nen­tal bal­lis­tic mis­sile] capa­bil­ity has gone no bet­ter than side­ways the past eight years, if not down,” retired Adm. Dennis Blair, a for­mer chief of the U.S. Pacific Command, tells the Washington Post.
“Less threat­en­ing, because less capa­ble,” agreed Rep. Mark S. Kirk (R-​​Ill.), who tracks North Korea.
At the same time, South Korea — which had been keep­ing the U.S. at arm’s length — is now draw­ing us in a lit­tle closer. Reunification talks with the Norks will con­tinue. But the South is now look­ing to put some of our short– and intermediate-​​range anti-​​missile sys­tems into place. Seoul’s “Defense Ministry… announced it plans to intro­duce 48 Patriot mis­siles between 2008 and 2009,” accord­ing to the Chosun Ilbo. “After 2009, it will intro­duce SM-​​2 Block-​​IV sea-​​to-​​air inter­cep­tor mis­siles to be car­ried on Aegis ships to counter the North Korean mis­sile threat.“
lat_nork_graphic.jpgJapan, mean­while, is bar­ring North Korea ships and flights — after agree­ing to install new mis­sile inter­cep­tors of its own, last month.
So: allies bet­ter defended, and adver­saries shown to be weak. That’s all good news, right?
UPDATE 11:14 AM: Unlike Phil Coyle, William Arkin thinks the American warn­ing sys­tem did a good job of pick­ing up on those Nork launches.

Within sec­onds of North Korean rocket engines ignit­ing on their launch pads, infrared cam­eras aboard Defense Support Program (DSP) satel­lites detected the heat and trans­mit­ted an alert back to U.S. com­mand cen­ters in Colorado Springs, where the tra­jec­tory was cal­cu­lated and the type of mis­sile deter­mined.
Those U.S. infrared satel­lites had been primed for over a month by activ­ity at the launch sites, intel­li­gence sources say. Movement was detected by spy satel­lites and U-​​2s, sig­nals were inter­cepted by NSA. North Korea even report­edly issued a stan­dard pub­lic “notice to mariners” announc­ing a mil­i­tary exer­cise and mis­sile test. 

UPDATE 11:39 AM: Plus, the Missile Defense Agency has to be psy­ched that it didn’t have to fire off its ICBM inter­cep­tors, since they haven’t been suc­cess­fully tested in nearly four years. “The appar­ent fail­ure of a North Korean long-​​range mis­sile gives the Pentagon some breath­ing room as it pre­pares two crit­i­cal tests for a U.S. mis­sile shield,” the Wall Street Journal notes.

To bol­ster mil­i­tary and polit­i­cal con­fi­dence in the shield, the Pentagon next month plans to launch an inter­cep­tor mis­sile in California to counter a mock enemy mis­sile fired from Alaska. The pri­mary goal of the trial isn’t to destroy the dummy war­head, said Rick Lehner, spokesman for the Pentagon’s Missile Defense Agency. Instead, it is to test the shield’s command-​​and-​​control sys­tem and ensure that a key radar sys­tem tracks the war­head and trans­mits infor­ma­tion to the inter­cep­tor.
Later this year, the agency plans a so-​​called hit-​​to-​​kill test that will aim to destroy a dummy war­head. Pentagon offi­cials say the two tests, which will cost between $85 mil­lion and $100 mil­lion each, make 2006 the key year for val­i­dat­ing the missile-​​shield con­cept. “We believe that we have demon­strated that the hit-​​to-​​kill tech­nol­ogy works. What we’re going to do is try to show that we can do it reli­ably and that we can sus­tain it,” Air Force Lt. Gen. Henry Obering, direc­tor of the Missile Defense Agency, said in an inter­view ear­lier this year.

UPDATE 1:49 PM: One other nice thing about the North Korean launch is that it gives the U.S. mil­i­tary a whole lot of data about a mis­sile it didn’t know much about before. Thanks, Kim!
