North Korean leader Kim Jong Un recently led the apparent launch of two short-range ballistic missiles matching the profile of either the KN-23 and KN-24 series from a mobile launcher. Pyongyang claimed the successful launch will “drastically improve the strike capability of the front units” and that it will “strengthen the effectiveness of tactical operation and variability of fire missions for the DPRK.” 

The description of the test implies the employment of a nuclear warhead in this system. If such a system is operational, it will mean a mobile nuclear missile launch capability will be delegated to tactical units inside the DPRK. This increases the chances of nuclear war by accident or miscalculation as well as by deliberate planning.
