In brief: North Korea and the nuclear issue one year on from the succession

After a failed ballistic missile launch by North Korea in April 2012, an apparently more successful one took place in December, characterized at the time by the regime as a satellite launch. The UN Security Council passed a resolution further toughening sanctions. North Korea has responded to the new sanctions with its customary threatening rhetoric and has announced that it is preparing to conduct a third nuclear weapon test, following on from those undertaken in 2006 and 2009. This note surveys the state of play on the nuclear issue in the light of internal developments in North Korea, where Kim Jon-Un appears to have consolidated his power.
