I have serious doubts they can manage anything more than a fizzle yield, but also only give them a one-in-three chance of a successful ballistic launch. It may be the case that they don't even have the preparatory work done, in which case hours isn't enough to launch, they'd need days/weeks. In any event, we're talking about one or two missiles only, and the Navy's ability to shoot those down in the midcourse/terminal phase is sufficient for such a small salvo.
If North Korea wanted to nuke us, they'd be better off handing the warhead off to some terrorist group to truck it across the Mexican border. Supposing their stuff is even small enough to smuggle.

But it doesn't have a China willing to rush in with 1 million PLA infantry. Which is really North Korea's only saving grace. Even if we got Kim out before they could mobilize, they'd be strutting and posturing for weeks, and there are any number of places they could fuck things up in retaliation. Korea, Taiwan, Philippines, Japan, they might even stir shit up with India. They could, one supposes, send a few divisions to Russia on loan, and enter into the Ukraine fray. And no clever strategy is going to counter that stuff. Some of this stuff they're already considering and only hesitant... a North Korea operation might goad them into working up the courage to try it.
