    Atomic Activity in North Korea Raises Concerns
    By DAVID E. SANGER and WILLIAM J. BROAD
    September 12, 2004
    http://tinyurl.com/5kb3d

    WASHINGTON, Sept. 11 - President Bush and his top advisers have received intelligence reports in recent days describing a confusing series of actions by North Korea that some experts believe could indicate the country is preparing to conduct its first test explosion of a nuclear weapon, according to senior officials with access to the intelligence.

    While the indications were viewed as serious enough to warrant a warning to the White House, American intelligence agencies appear divided about the significance of the new North Korean actions, much as they were about the evidence concerning Iraq's alleged weapons stockpiles.

    Some analysts in agencies that were the most cautious about the Iraq findings have cautioned that they do not believe the activity detected in North Korea in the past three weeks is necessarily the harbinger of a test. A senior scientist who assesses nuclear intelligence says the new evidence "is not conclusive," but is potentially worrisome.

    If successful, a test would end a debate that stretches back more than a decade over whether North Korea has a rudimentary arsenal, as it has boasted in recent years. Some analysts also fear that a test could change the balance of power in Asia, perhaps leading to a new nuclear arms race there.

    In interviews on Friday and Saturday, senior officials were reluctant to provide many details of the new activities they have detected, but some of the information appears to have come from satellite intelligence.

    One official with access to the intelligence called it "a series of indicators of increased activity that we believe would be associated with a test," saying that the "likelihood" of a North Korean test had risen significantly in just the past four weeks. It was that changed assessment that led to the decision to give an update to President Bush, the officials said.

    The activities included the movement of materials around several suspected test sites, including one near a location where intelligence agencies reported last year that conventional explosives were being tested that could compress a plutonium core and set off a nuclear blast. But officials have not seen the classic indicators of preparations at a test site, in which cables are laid to measure an explosion in a deep test pit.

    "I'm not sure you would see that in a country that has tunnels everywhere," said one senior official who has reviewed the data. Officials said if North Korea proceeded with a test, it would probably be with a plutonium bomb, perhaps one fabricated from the 8,000 spent nuclear fuel rods that the North has boasted in the past few months have been reprocessed into bomb fuel.

    A senior intelligence official noted Saturday that even if "they are doing something, it doesn't mean they will" conduct a test, noting that preparations that the North knew could be detected by the United States might be a scare tactic or negotiating tactic by the North Korean government.

    Several officials speculated that the test, if it occurred, could be intended to influence the presidential election, though a senior military official said while "an election surprise" could be the motive, "I'm not sure what that would buy them."

    While the intelligence community's experience in Iraq colors how it assesses threats in places like North Korea, the comparisons are inexact. Inspectors have seen and measured the raw material that the North could turn into bomb fuel; the only question is whether they have done so in the 20 months since arms inspectors were ousted. While Iraq denied it has weapons, the North boasts about them - perhaps too loudly, suggesting they may have less than they say.

    On the other hand, the divisions within the administration over how to deal with North Korea mirrors some of the old debate about Iraq. Hard-l

He very well knew that there would be no way for it to pass the House and the Senate, but sponsored it as a political statement.

    It appears that the Selective Service system is gearing up for a new national draft, probably to be next spring. This draft is for both men and women from 18-25 but people with computer or medical training will probably be required to register them (and any new skills they acquire in these areas) until they turn 35.
    Registration of training and skills, as far as I know, is something that occurs only once the draft has been implemented. What's technically required from the age of 18 to 35 is that the registrant inform the SSS of their current address, even though at the moment this is unenforced. Seriously, how many citizens remember to register their new address with the SSS when they move? The SSS had problems with tracking down registrants during the Vietnam-era draft.

    Except for the issue of women in the draft (which Rep. Rangel included in the proposed bill to make it even more controversial), how has this changed from previous years? Are they really preparing for a "new national draft", or are you just saying so because you read the SSS's Annual Performance Plan?

The North Koreans then used their "peaceful" nuclear program with assistance from Abdul Qadeer Khan from Pakistan to develop their own nukes thus secretly breaking their agreement. North Korea also has an active missile programs and has conducted "test firings" of multi-stage missiles - shooting them over Japan. Japan is not very happy about this.

    The U.S. with U.N. backing (the Soviet Union's UN ambassador had walked out - thus avoiding a veto) fought a war with the North Koreans in the 1950's. The war ended with an armistice in 1953 - not a peace treaty. North Korea has a 1.1 million man army out of a population of 22 million. They spend about 23% of their GDP on the military. The South Korean capital - Seoul is within easy artillery range of the North Korean border, and the North Koreans are believed to have a lot of hidden artillery in bunkers on the border. In the event of war, a lot of civilians in South Korea would die quickly. Finally, North Korea's leader Kim Jong-il is a wacko. While his people starve, he imports large quantities of large items for himself (he favors Hennessy cognac). He's had Japanese citizens kidnapped to teach the Japanese language to North Koreans spies . He's a movie nut (owns 20,000 films) and kidnapped a South Korean movie director to make films about himself.

However, with China's economic boom - China now trades far more with South Korea, Japan, and the U.S. Nevertheless, China is still wary of Japan - remembering the horrors inflicted on China by the Japaneses during WWII. Since the war, Japan has become an economic rather than military power, and it's pacifistic constitution (written by the US) ensures that it will not again become a threat to it's neighbors.

    A nuclear North Korea threatens the balance in the region. It is not in the interest of China for South Korea to develop it's own nukes. It is not in the interest of anyone for the Japanese to develop nukes to counter the threat of nuclear armed missiles from North Korea. China's real nightmare - is if the region starts a nuclear arms race and Taiwan goes nuclear.

    So, the choices are as follows:

    1) Cut a deal similar to the 1994 Carter deal that the North Koreans violated (fool me once ...)

    3) Drag China into the negotiations with North Korea and convince them to "curb your dog".

The reason is that you need a critical mass of fissile material for an explosion to occur at all. The critical mass of U235 corresponds to a yield of over 100 kilotons; fission bombs usually yield less because only a small fraction of the uranium in a bomb actually fissions when it goes off. (The Hiroshima bomb had a yield of about 20 kilotons.) You can get a smaller yield by building a less efficient bomb, but the main factors determining the efficiency are the neutron/uranium reaction cross-section and the branching ratios, which are physical constants.

      You're wrong. Do a bit of web browsing about the threat of nuclear terrorism sometime. Try this paper for a start. What you're missing is that there is another critical factor determining the efficiency -- for what time period the assembly is critical. A group with limited resources trying to build a nuclear bomb for the first time is likely to aim for a device with a minimum of technical sophistication. This means one of two designs, corresponding to the bombs dropped on Hiroshima and Nagasaki. One was the "gun design," so named because a slug of uranium is shot into another subcritical mass of uranium. The other is the "implosion design," where a hollow sphere of plutonium is surrounded by shaped charges of convential explosive, which when detonated compress the plutonium into a super-critical density. The problem with these designs is that if you do a shoddy job building the thing, the nuclear chain reaction will take off when the fissionable material is only partway to the final "assembled" state. Then most likely the nuclear explosion blasts the parts back apart before they ever reach the final assembled state, and this flying apart of the material makes things subcritical again before much of the nuclear energy is released. This can lead to arbitrarily small yields. This is particularly likely (or maybe almost inevitable) if a bomb is built with the less-refined "reactor grade" materials as opposed to the more-refined "weapons grade" materials. The less-refined material has a far greater proportion of undesirable isotopes which randomly decay releasing extra neutrons which will start the chain reaction before the optimal stage of assembly.

    It was reported that there was a massive explosion Thursday around the town of Yongjo-ri, Kim Hyong-jik County, Ryanggang Province. U.S. Department of State, sources familiar with North Korea and the Korean government all confirmed the explosion. A high-ranking government official said Sunday, It is true that a large mushroom cloud about 3.5 to 4 km in diameter was observed by a satellite at around 11:00 a.m. Thursday. It was not a nuclear test, but the explosion seemed to be three times bigger than the one that took place during the Ryongchon Station accident,± and added, Both U.S. and Korean intelligence authorities are investigating what caused the explosion.±

    Chong Wa Dae Spokesman Kim Jong-min said, We noticed the explosion right after it took place and reported it to the president in writing during a National Security Council meeting. But we cannot decide the nature of the accident yet.±

    The accident took place in a mountainous region 1,500 meter above sea level around Yongjo-ri, where it is known that there were many munitions factories nearby. In particular, the exact spot of explosion is only 10km away southwest from the Yongjo-ri base for Rodong 1 and 2 missiles and some 30km away from the Sino-Korean border.

    There is much talk about the cause of the explosion. The government official said, If a nuclear test causes an explosion, we can detect it by reading satellite data. Thus, the recent explosion in North Korea was not caused by a nuclear test.± The intelligence authorities assume that an ammunition depot with over 1,000 tons of dynamite or an ammunition car may have exploded, or there may have been a chain explosion of chemical material or a big fire. Some Chinese sources argue that a massive explosion took pace in a munitions factory. Hong Sun-jik, director at the Hyundai Economic Institute said, Other than the assumption that it may be a simple accident that took place due to old facilities, we cannot exclude the possibility that the explosion may have taken place due to the lack of control of the Kim Jong-il regime, or it may have been connected to a secret feud over the successor of Kim Jong-il following the rumor of death of Kims wife, Ko Young-hee.±

    Also, some strongly argue that it is not a simple accident because it took place on Sept.9, the Norths foundation day, which is considered a very important national holiday. Others argue that with Koreas nuclear experiments in the past at issue in the international community, it could be a false explosion by North Korea to intensify the Koreas nuclear issue. In other words, the North intentionally caused the explosion to deliver a message to the international community.

    Don't believe everything you learn in a class, particularly such a politically-oriented one.

    In the Manhattan Project docs, they make it very very clear that Japan was sending out "peace feelers" and trying to surrender in July.

    Did they mention the conditions? Early on in the war, the Allies had decided that they would accept nothing less than an unconditional surrender. Being able to put conditions on your surrender is one of the rights you lose when you go on an unprovoked rampage and kill millions of people, and require the entire might of the free world to put you down. The "peace feelers" the Japanese were sending out did not allow for an unconditional surrender, and were therefore (rightfully) unacceptable to the Allies.

    Russia was set to invade along with the United States a week after the bombs were dropped, and the estimated casualties in the Manhattan Project docs were 40,000 Russians and Americans at MOST. The millions of lives lost came from an article by Henry Stimson (Secretary of War at the time) in order to silence critics of the atomic bombings.

When examining this, keep in mind that "only" 80,000 people were killed in the Hiroshima bombings. Any alternative action that kills more than that comes out as a net loss. Also keep in mind that Okinawa makes about 0.6% of Japan's total land area, and (as of today) about 1% of Japan's total population.

    The battle of Okinawa lasted about 82 days. American casualties during the battle were just under 16,000 killed and 38,000 wounded. Japanese casualties include over 100,000 soldiers and 100,000 civilians killed. The battle for a relatively tiny island in the middle of the ocean cost over 200,000 Japanese lives, already more than the total number of deaths in both atomic bombings. To imagine that the whole of Japan could be taken, when its very women and children were being trained to fight to the death with sharpened bamboo stakes, with fewer than 180,000 deaths (the number from the atomic bombings) on both sides is dubious, to put it extremely mildly. Your figure of 40,000 deaths on the Allied side is vaguely plausible, although incredibly low, but in battles with the Americans, the Japanese were having trouble killing a single American soldier without losing five or ten of their own, and there is no reason to expect that this would improve given their seeming inability to learn from experience that they displayed throughout the war. Combine the land battle with continued conventional strategic bombing and it would take nothing short of an act of God to kill "only" 180,000 people during the invasion. Getting under the "only" 80,000 killed at Hiroshima might even be beyond His powers.

    We basically bombed Japan so that we could claim sole credit for their surrender, and so that we could get the first "hit" on Russia in the cold war by showing off our pretty weapons.
