According to U.S. and possibly foreign intel, North Korea appears to be preparing for a nuclear test. That being said, the ingestion of a grain of salt is recommended.
The testing of a nuclear explosive by North Korea at this time is doubtful, but highly possible.
"It is the view of the intelligence community that a test is a real possibility," said a senior State Department official.
A senior military official told ABC News that a U.S. intelligence agency has recently observed "suspicious vehicle movement" at a suspected North Korean test site.
The activity includes the unloading of large reels of cable outside P'unggye-yok, an underground facility in northeast North Korea. Cables can be used in nuclear testing to connect an underground test site to outside observation equipment. The intelligence was brought to the attention of the White House last week. (via Drudge)
Kim Jong Il is undoubtedly in search of power and international attention, and what the intel reports are showing is likely to be exactly what it is, preparation, without an explosion.
Pending an underground nuclear blast, the international community shouldn't give the attention North Korea asks for, rather show a will to potentially embrace them upon much needed change in government and policy, as well as attitude.
If there is such a test, assume every terrorist group, Iran and North Korea are very nuclear.
