There is an alternative view that the world and the USA suddenly come to terms with the fact that N Korea is an established nuclear power and has become another member of that horrific 'select club' of countries that hold a nuclear deterrent and 'back off' - let diplomacy prevail 'or else'!! Aye, it's the dark legacy of the discovery of the atomic bomb during the famous Manhattan Project. Oppenheimer's chilling remarks later on re ever being involved with this deadly device/WMD and it's successive more deadly nuclear 'brothers', are so contrite and prophetic!!
