It is highly unlikely that the Democratic People’s Republic of Korea (DPRK) would intentionally launch nuclear weapons in the absence of an existential threat to the continued survival of the state and its political leadership. However, in the event of such a scenario—for example, the prospect of an imminent US invasion or regime change operation—it is possible that the DPRK would use some of its estimated forty to fifty nuclear weapons in an attempt to forestall US action. In that case, the DPRK could use its short- and medium-range ballistic missiles early in a conflict to strike political and military targets in the Republic of Korea (ROK) and Japan, it and could potentially use its intermediate-range and intercontinental ballistic missiles to strike US military targets on Guam and Hawaii. The DPRK could also hold some nuclear weapons in reserve to strike the continental United States with intercontinental ballistic missiles, in the event that its initial nuclear strikes did not prevent an existentially threatening conventional invasion of the DPRK. First nuclear strikes by the United States (and its allies), or by China or Russia, may also be unlikely in the absence of an overwhelming provocation, but the nuclear weapons and launch systems available to these states are also considered.
