tomahawk6 said:The most efficient is by ballistic missile. I don't know if the North Koreans have the technology to do that. The goal would be to create an EMP,which would shut down everything electronic.

WHAT IS A 'DIRTY BOMB'?
TIME Pentagon correspondent Mark Thompson explains:
"Dirty nukes are what you may choose to build if you're unable to create a real nuclear bomb, i.e. one whose explosion is based on a nuclear reaction. A dirty bomb is a conventional explosive salted with radioactive isotopes in order to spew out that nuclear material and contaminate a wide area. The military usefulness of such devices have always been in dispute. In fact, the TNT in such a bomb may still be more dangerous than the nuclear material. Its destructive power would really depend on the size of the conventional bomb, and the volume and nature of the nuclear material.
"The assumption has been that forces who would build a dirty nuke would do so because it's far, far easier than to build a nuclear bomb. It's unlikely to kill 10,000 people, but any bomb that killed people and set off Geiger counters would terrify a whole city. It's ultimately a pure terror weapon."

Old Sweat said:As of today the North Koreans are in control of events. They do not even have to have a warhead or even a dirty bomb; all they have to do is keep the possibility alive..
armourmike said:I disagree. IMO the Americans have control of this. If the North launched any missile at the Americans in Japan or ROK, or anything bigger than an artillery shell at ROK, the Americans will shoot it down and then go on the offensive.
Old Sweat said:My point is that the possible existence of one or more nukes makes any escalation by the US, China, Japan or SK far too risky, unless there was a massive NK attack on the south, and that is unlikely.
armourmike said:I think that its more the fact that if the US moves without substantial provocation they risk escalating tensions with the Chinese, then the possible possession of a nuke by DPRK. If the US was to become the aggressor tomorrow, many countries would be angered and the Chinese would be especially angered. If DPRK throws the first punch and then the US attacks, very few countries would see it as an unjustified attack or react negatively.
There's an interesting article about the Chinese and supporting the DPRK. Its been noted before the reduction of aid since February as well as a drastic reduction of arms shipments, but this is the first time Beijing has come close to outright condemnation of DPRK.

South Korean ministry: 'Indication' that North Korea preparing for fourth nuclear test
SEOUL, South Korea - South Korea's point man on North Korea said Monday there is an "indication" that Pyongyang is preparing for a fourth nuclear test, a day after another Seoul official said a Pyongyang missile test may be in the works.
Unification Minister Ryoo Kihl-jae told a parliamentary committee Monday that "there is such an indication" of nuclear test preparations at Pyongyang's site in the country's northeast, according to two ministry officials who spoke on condition of anonymity because they were not authorized to speak publicly on the matter.
Either a nuclear test or a missile test would escalate tensions that have been rising for weeks on the Korean Peninsula, and could invite a new round of U.N. Security Council sanctions over North Korea's nuclear and rocket activity. The U.S. and South Korea have been raising their defence posture, and foreign diplomats were considering a warning from Pyongyang that their safety in North Korea could not be guaranteed beginning Wednesday.
North Korea has unleashed a flurry of war threats and provocations over the U.N. sanctions and ongoing U.S.-South Korean military drills, which the allies say are routine but Pyongyang says is a preparation for a northward invasion.
Ryoo made his comment in answering a lawmaker's question about increased personnel and vehicle activities at the North's nuclear test site.
Ministry officials cite Ryoo as telling the lawmakers he wouldn't provide further details because they involve confidential intelligence affairs.
South Korean defence officials previously said the North completed preparations for a nuclear test at two underground tunnels. The North used one tunnel for its Feb. 12 nuclear test. The second remains unused.
