I did find it amusing that American sees itself as the global nuke police when they are the source of much of the world conflict, and with Trump at the helm I see him as being the most likely candidate to metaphorically rub one out in a fit of fire and fury the like of which the world has never seen.
It still is bluff on both sides, US V NK. Un knows full well he MIGHT have a couple of nukes but not small enough to mount on an ICBM but maybe in a year or two they might miniaturize them but even if he has a few ICBM's with nukes, they are not going to be at the extreme power level of US nukes which go up to multiple megaton range.
That and we do have thousands of weapons, sub launched, aircraft carrier launched, jet figher/bomber launched and ICBM's.
He would be totally overwhelmed in a real nuke battle and there would be no more NK, and probably nobody could even ive there for a few centuries after such a stupid nuke attack.
Knowing that, Un is playing a rough game of chicken. His hope is to show he has nukes and thus build up his street cred only in the hopes of better sanctions deals.
He may be mad but he is not stupid.
If I were president, I would order every missile launched by NK to be shot out of the sky, weaponized or no. That would send a message to NK, we don't fear your piddly little rockets, we can shoot them down at will but I don't think Trumpf has the subtility to think in those terms. The down side is Un may consider it an act of war and immediately strike Seoul with everything he has depending on just how mad he really is.
Another player is Japan, THEY might start shooting down Un's missiles on their own. I would think hard and long about that possibility if I were in Japan leadership since all the ICBM's are hitting close to Japan already, the last one went up over 3000 Km high which means it was designed to do a short flight horizontally, if the same missile was aimed lower, say max 300 Km high the angle would be a lot lower and the end point a LOT further away.
Still, I think Un is just blustering and bluffing to get the US to lift sanctions.
And like the OP says, what to do about US missiles. Not much anyone can do about that, the same with Russian missiles, Chinese missiles, British, French, Italian, German missiles either. Granted we have thousands, we are down by 90% of what we used to have. Since we cannot test them for real, they are also deteriorating and have a decent chance of not igniting fission or fusion when it lands or shortly before, however they intend to do that. We might have 50% duds but that still leaves us with a powerful hand nuke wise.
I would love to see a strike team go into Russia, China, US, britain, France, Germany and so forth, kidnap ALL the damned warheads and bombs and launch then into the sun but that's not going to happen, just pipe dreams.
Even if that happened, new work would begin immediately on making replacement nukes.
