In a few years. When they’ve miniaturized and miniaturized and hardened nukes for launch and re-entry. The time to prevent that is now. And many presidents prior.

That's an optimistic and probably incorrect view of things. There is much to suggest they have these capabilities now. It's a risk not worth taking. You need a *REALLY GOOD REASON* to think deterrence won't work with them before you decide to risk hundreds of thousands of lives.

What suggests they have those capabilities? (To marry a miniaturized nuclear warhead into a viable RV on an ICBM capable of accurately hitting the US). Outside of mountain nukes and the recent HS-15 test.... how do we get from that to there?

Let's flip the question: what would make you think they *don't* have the ability? Every other nuclear state at a comparable level of testing has had the ability. It is also +50-year-old technology. So what's the rationale for thinking they can't do it, besides unbridled optimism?

DPRK isn’t China, Russia, et al. Not even close. So let’s not flip the question. Why the unbridled pessimism? Let’s talk reality. They haven’t proven it, yet. If there was ever a state which needed to prove it, based on infrastructure and resource limitations alone, it’s DPRK.
