There are lot of global chess moves going on right now. Best for NK not to forget about checkmate.

It's a cash shakedown alright but they are proceeding toward the 'line in the sand' no doubt.

(Approximate translation from the original Japanese): Statement is now made tonight, US time, about a South Korean team of specialists (geology) being placed on total alert. The team was activated in the city of Taejon recently, at a special institute for geology/earth studies connect to Army. The team was activated around the missile launches of July, but this shows the strongest movement/reaction by the South Korean army in response to reports the North may actually test a nuke.The report is that there are 30 monitoring stations around the south, and recently new ones have been established by the DMZ. The word of any kind of massive explosion of any kind triggers CTBT reporting procedures to Vienna, Austria.
