As if any US government likely to be elected in the next decade will accept that. Even Obama wouldn't have.
That said, we seem to accepted the addition of Pakistan and India to the nuclear club even though that's potentially just as destabilizing as NK having nukes. And no one, even the Arabs, seems to be making a fuss about Israel's likely possession of nukes (or at least the technology to build them), which is one of the world's worst kept secrets.
Personally, Trump and Putin with nukes makes me more nervous than Kim with nukes. Kim is unlikely to ever possess enough to do much long term damage. He's a threat to his neighbours but not the world. Both Trump and Putin could easily end civilization with a flick of a button. Trump is easily as unstable as Kim while Putin is very much in the mold of classic Russian autocrats like Peter the Great and Stalin.
