As for South Korea, it can bulldoze over North Korea with conventional weapons. It doesn't need nukes to defend against North Korea. On the other hand, China has so much firepower that having a few nukes won't tip the balance much, so nukes are not much useful against China either. Sure, but they’d have turned Seoul into a series of shallow craters however, and you should assume that China would use the DPRK as a proxy in another shooting war. Meanwhile having the credible ability to destroy a few major Chinese metropolitan centers probably has more of a deterrent effect than you are admitting.

We don't need nukes to deter China (or any other country) from an all-out invasion. We already deter them by being a small, heavily populated and industrially developed, largely monocultural, and largely mountainous country, which has half a million soldiers and is only accessible via sea or through one of the world's most heavily fortified border. Invading South Korea will cost any country more than Invading Iraq cost America. It's simply not worth it. That's not saying South Korea is invincible, or there aren't any ways China can apply military pressure. A much more realistic scenario is like this: some Chinese patrol ships suddenly find a need to "protect" Chinese fishing boats from being "harassed" by South Korean coast guards patrolling its EEZ. In such a case, nukes won't help, because what are you going to do with them, bomb Beijing? Can you imagine what would happen to KOSPI index if a South Korean politician so much as made a joke about using nukes? I still fail to see the utility of nukes. Any national leader has to be batshit insane to consider invading South Korea, and if they are already that insane, I don't see how having a few nukes will suddenly cause them to back down. (Don't be fooled by North Korea: they're carefully cultivating the image of a batshit insane trigger-happy country because it benefits them.)
