Unfortunately I think the response to being attacked is to retaliate, justified either preemptively or post-event.
I think in the grand scheme of apocalypse, the US comes out pretty well against NK. Mostly because they have fewer nukes than we have surface area. OTOH, the US has enough nukes to turn that entire country into glass and poison that entire countryside for forever.
But who knows. Maybe NK's allies, mainly China, decides they've had enough of that BS and they fire off too, in which case the world explodes and life recedes back into the seas until the radiation cools down ... or we just become Venus' twin.
At any rate, the media won't slow things down and bring to the table level-headed conversation. We seem to be operating at a pre-scientific level of thought, where emotions and 'feelings' are how we have decided to observe the world. Maybe if we could all just go back to the dark ages for a few millennium (with the help of Little Boy and his friends), things would come out better next time around
