is there any point in having nuclear weapons anymore?

Ultimately you need a significant nuclear arsenal to pose a real military threat, and likely only America, Russia, and possibly China have that. Otherwise the threat is more psychological (you can do a fair bit of damage with one nuke, of course, but it wouldn't be enough for North Korea to just nuke, say, Seoul to stop South Korea, but in an ideal world, Seoul wouldn't get nuked at all, which really raises the costs of waging war on North Korea, playing to their advantage in negotiations.

This assumes, of course, that cooler heads prevail in the upper echelons of government. The kind of brinksmanship that led to World War I, for instance, could easily just see the nukes being used.

Even with the recent threats from North Korea to nuke America, it just won't happen unless the regime is just insane and doesn't care anymore. Despite the potential threat North korea has on it's neighbours by having nukes, i don't see them doing something that would lead to there demise. The regime of Kim Jung Un is what North Korea is, thats it. North Korea is nothing without it's crazy government.
