I agree that North Korea keeping up with it´s current behavior is dangerous, it´s just far from clear whether a regime collapse would make things better or worse. The safest solution might be something like a soft collapse where the Kims and their friends are offered a safe retirement in China en exchange for stepping down and letting South Korea and/or Soutj Korea take over (which is unlikely unless China is threatening military action otherwise—and since China does’t want Japan to go Nuclear, it has an incentive of finding some way to calm down the Kims).
