Article Highlights (From Bulletin of the Atomic Scientists)

In the January/February issue of the Bulletin of the Atomic Scientists, Siegfried S. Hecker and Robert Carlin assessed North Korea's nuclear developments in 2011. That assessment preceded the death of Kim Jong-il on December 17. This article supplements the Hecker/Carlin piece with detailed overhead imagery, additional analysis of Pyongyang's march toward a more threatening nuclear weapons capability, and brief commentary on how the accession of Kim Jong-un to leadership may influence North Korea's nuclear trajectory.
