North Korea [Democratic People's Republic of Korea—DPRK] conducted its third nuclear weapons test on 12 February 2013 with a yield that most estimate was around 6 to 10 kilotons. The test came on the heels of a December 2012 missile launch that placed a satellite into orbit though reports soon indicated that the satellite was not functioning properly. Given North Korea's actions and apparent determination, any chance to achieve complete and verifiable denuclearization may be long gone.
