I doubt Kim’s Young’un would pop off any missiles at US or US interests. The one thing that drives him is his own survival, he’ll even take out family members along with any official that he suspect pose a danger to his status as the ongoing “great leader-ness”.
He knows that whatever damage he could inflict on the US, it would be dwarfed by what the US would do to NK. It would mean the end of NK, the end of the Kim dynasty and likely the end of his own life. No more movies, expensive booze and food, women or basketball for him. He’s not the suicidal-kamikaze type.
