North Korea: A series of satellite images has given the clue that North Korea is preparing for another nuclear test. New activity was detected at the Punggye-ri test site where several large vehicles were parked near the tunnel entrance. They also detected new activity at the south portal, where an existing tunnel has been widened and graded. There is a widespread speculation that North Korea will mark the 70th anniversary of the Workers’ Party on Oct. 10 with either a missile launch or a nuclear test. If North Korea opts to detonate a nuclear device, it would mark the fourth test in its history. The impoverished country believes nuclear armament is a key deterrence against external foes, most notably the US.
