North Korea, as a member of the "Axis of Evil", has been labelled as a state of concern by the U.S. Government due to their alleged possession of weapons of mass destruction (WMD). It is well known that North Korea holds advanced missile and nuclear technology, and is suspected to have, according to U.S and South Korean sources, stockpiles of foremost chemical weapons. This report evaluates why and how North Korea´s chemical and biological programmes developed, most likely for different purposes, and how their strategic importance seems to have decreased with the increasing difficulty in obtaining materials used for production and development related to control mechanisms. It also discusses chemical and biological weapons (CBW) lessened significance in regards to North Korea´s military defence compared to the nuclear capability. In addition, the report maintains the possibility that if Pyongyang would reassess the importance of CBW, it is most likely that North Korea still have stockpiles of chemical weapons for use, and the technology and knowledge to shift dual-use facilities for clandestine production, in both the chemical and biological fields.
