North Korea Able to Test Nukes in Two Weeks, Study Says

North Korea is technically capable of conducting a nuclear test in as little as two weeks, according to a study published by the Bulletin of the Atomic Scientists.

Commercial satellite imagery shows an underground tunnel has been prepared for containing a nuclear explosion near the sites used for the regime’s two earlier tests in 2006 and 2009, according to the study written by Siegfried Hecker, a scholar on North Korea’s nuclear program at Stanford University in California, and Frank Pabian, a geospatial information analyst at the Los Alamos National Laboratory.
