It will probably end up the same way as other states have managed to develop nuclear weapons; sabre rattling for a while, (or in the case of Israel, SILENCE) then acceptance of the fact that there are one more nuclear power in the world.
A NK “respected” as a country with status as a nuclear power and accepted into the club, MAY be easier to deal with than one that feel threatened with annihilation and political isolation.
That policy has been tried for decades and not worked. Time to think anew??
