The nukes have many roles perhaps but I think the fully developed weapons are for retaliatory strike.
They are the North Korean leadership saying that if the US (or China or anyone really) tries to surgically decapitate them (like the US just did in Venezuela) then the nukes are used to take the attackers with them
Yes that's the orthodox doctrine of nuclear deterrent. To be truly effective you need a triad of land-based ICBMs, nuclear-armed submarines, and aircraft-based delivery systems so that your second-strike capability remains intact through any decapitation attempts.
If you don't have the triad then you need to brandish your capability more ostentatiously, like France does with its deliberate refusal to commit to a no-first-strike policy. This is (one of the many reasons) why North Korea does so much sabre-rattling: they don't have a (publicly known) nuclear triad for deterrence.
Just a note that the importance of the triad is a very American perspective on deterrence and most other countries don't seem to approach this the same way the US does.
The Russians really have a quad (they also have mobile, truck mounted ICBM's that form a significant part of their deterrent, offering some of the guaranteed second-strike advantages that the US gets from SSBN's- and which their SSBN program does not provide nearly as well as the USN does). The Chinese only recently added a manned aircraft leg of their triad with the JL-1. The Indians technically have a triad- just no silo based systems, all of their land based missiles are from TELs, and they only have two SSBN's and do not do alternate crews so more than 1/3 of the time they don't have any deterrent at sea. The Israeli's are not believed to have any sea-based ballistic missiles, their sea-based deterrent would be Popeye cruise missiles and so vulnerable to interception. The Pakistanis are still building their first sea-based deterrent. The French and the UK have no land-based missiles, they are only sea-based and airplanes. The South Africans invested in the Jericho missile more for its space launched capabilities than its warhead delivery abilities, and never really looked at anything sea-based, so far as is publicly known.
I don't agree regarding a quad vs a triad.
At risk of sounding like gpt, the triad is not silo/boomer/bomber, it's land-based/airborne/seaborne.
Whether or not the survivability of your land-based ICBMs are due to mobility or hardened bunkers doesn't change much at the strategic level.

The core parts for MAD land-based missile silos (to soak up the enemy's missiles) and submarines (to ensure a second strike). Planes are largely a diplomatic deterrent inasmuch as they're easy to send out and easy to recall.
But Pyongyang isn't playing MAD. It's playing credible threat. And for a credible threat, you just need missiles. (On land or on subs.) The point is that you raise the stakes of e.g. a Maduro operation to risking Los Angeles.
Strategic bombers are just as important because MAD itself is fundamentally a political and diplomatic tool. The reason you have strategic bombers is, as you correctly said, so that you can signal your posture and intent by stationing them, dispersing them, launching them, and (most critically) recalling them.
But again, because MAD first and foremost is a deterrent, you want to provide diplomatic offramps for both you and your adversary. This is crucial. Putting the B-52s on airborne alert sends a very strong message, but so does recalling them from airborne alert.
By their very natures, SSBNs and ICBMs are not capable of playing this role.
P5 by triad capability:
Looks like IN ought to get Airstrip One's seat?
Guess the US's mistake was not decapitating NK earlier then. Too late for NK, not too late for other regimes.
Guess you missed why NK wasn’t decapitated earlier.
Why are you guessing that?
