Civilians like us can't know this, but it has been hypothesized that one of the levers being used on China with regard to North Korea's development of nuclear weapons is explaining to them that if North Korea goes nuclear, they can expect Japan, Taiwan, South Korea, and who knows who else to go nuclear, either via local development of the weaponry or via assisted…
> We'd probably know if they'd ever tested a weapon. We wouldn't necessarily know if they'd actually built one. If I were them, I totally would have. What's the point of having nuclear weapons and not telling everyone? The entire point of nuclear weapons is to deter attacks.
The point is so that:
(1) You can maintain the highest ground in proliferation discussions focussed on rivals, and
(2) Reveal your own weapons quickly if the geopolitical situation shifts (either as deterrence or, should the situation shift too quickly for that, direct use to blunt an existential threat.)

No, it's (as with any weapon) to provide the capacity to destroy the enemy if needed.
Like any weapon, this capacity can be publicized to deter attacks, but that is not the sole purpose of the weapon, and it can't be, because deterrence cannot work if it is perceived as the sole purpose of a weapon.
