Adding to your point, Seoul is visible from North Korea, and vice-versa, and likely has enough conventional artillery aimed at it that even without nukes an invasion would be Very Bad for the Korean people.

None of that would stop the current US administration from launching a sneak attack as we've seen several times in other countries. They simply do not care about consequences.

What is the analogous example or your argument? Was iraq sitting next to a china-grade neighbor? Who's venezuela china?

I assume you mean Iran rather than Iraq, but your point still stands.

North Korea is in such poor shape that they probably can't maintain much of the equipment much less keep the personnel trained and ready to use it effectively. Not a reason to go to war, but the threat to Soul and SK in general is likely massively overstated.

I think the strategic rational for unification completely swapped about 20 years ago. Up until the early 2000s it was likely in South Korea's, and the US's, interest to find a way to topple NK and unify the peninsula. The two populations had blood ties and common culture. Technologically the gap was growing but still reasonable. It would have been close to an east/west Germany type of situation where unification took effort but ultimately was clearly beneficial. China (and Russia) would have been losers in that unification would have brought a western friendly government even closer to their border. Additionally, NK still had a chance of re-energizing and becoming a real threat to SK.

Now however NK is in such bad shape that unification would be traumatic. South Korea would take on a problem of epic proportions, caring for and bringing a population of that size back into the broader world would be exceptionally costly and definitely not guaranteed to end well, possibly destabilizing SK in the process. Their cultures have grown apart making it hard for them to understand each other. The blood ties are not really there anymore. China and Russia would likely be the winners in that everyone sees NK as crazy and anyone helping them is hurting the world so they could get rid of that baggage. China especially would gain by having rail access to massive shipping assets to deliver goods even cheaper to the world. Finally, the US would loose a major rationale for stationing forces that close to China. They could, rightfully, say that NK isn't a threat and the massive US assets in South Korea and Japan should be drawn down.

> North Korea is in such poor shape that they probably can't maintain much of the equipment

Sadly we know from events in Ukraine that NK artillery works and that they have plenty of it. Yes, it's poor quality, but far from harmless.

Also to be clear: artillery is not exactly rocket science. They idea that NK doesn't have huge stockpiles is ludicrous.

It takes more than stockpiles of shells to be able to use it and maintain offensive positions capable of causing harm. From the reports I have seen NK military in Ukraine has been mostly cannon fodder and they are very untrained. That being said, joining the war effort in Ukraine is likely increasing their readiness.

Right... shells age. They blow up in the barrel, things like that. Maybe they even intentionally blow up in the barrel. Not that I would suggest sabotage. There's no way South Korean intelligence could possibly infiltrate North Korea ;)

But even so, if there was a serious threat of war, which is unlikely because China would stop North Korea, the US would place assets in the region and as we got close to a confrontation the US and South Korea (and as things are looking, probably Japan) would begin an aerial and missile bombardment to destroy in place North Korean offensive capabilities. Some would get through of course, perhaps thousands or tens of thousands of South Korean casualties, but in the context of a conventional war North Korea's capabilities would be quickly overwhelmed, at least in my opinion.

But honestly, the current status quo works pretty well for everyone except the people of North Korea, but there's not much we can do. It's a tragedy and the blame for that falls squarely on the Soviet Union and Chinese Communist Party.

... And the US, who razed every building in North Korea and killed more than 10% of the entire population of North Korea (that's entire population, including civilians).

Nope. US was there under a UN banner, and the UN force was winning until China threw manpower into the war. Never mind Soviet support. The blame goes to the communists and them alone. Without them Korea would have been likely unified under what is now the democratic South Korea we know today, but the communists in China couldn’t have a democracy so close to them, so they fought to win and establish the brutal regime that we have today in North Korea.

> Some would get through of course, perhaps thousands or tens of thousands of South Korean casualties

This seems rather optimistic considering an incredibly dense South Korean city of 10M people is 20–30 miles from North Korea.

Yea I'm being optimistic - but the buildings themselves provide shelter, plus Koreans can take to the subway.

Isn't artillery precisely rocket science?

No, it is precisely ballistics.

Propellant stored in the projectile vs propellant stored behind the projectile.

Thank you.

The only way unification can ever happen will be with Chinese blessing, with or without democracy. That would mean a full exit of US forces from the peninsula, and substantial pandering to the CCP and influence in Seoul. Which isn't that far off a thought honestly - for the most part, Korea was a tributary of China. With rapidly changing demographics and economic heft in both countries, it's even more likely SK will gravitate towards China, to the point that the Chinese will find more persuasion in unification and predictability.

All probably close to correct. I wasn't arguing that unification would, or should, happen (especially by force). I was arguing that the strategic value to China, SK, the west, etc have flipped as well as the actual capabilities of NK are likely vastly overstated.

The joke here is that in 20-50 years I'll bet worst Korea will be begging best Korea to reunify given the absolutely apocalyptic state of TFR south of the 38th parallel.

Another fun trivia: Seoul and Pyongyang are closer than Washington DC (Union) and Richmond VA (Confederacy) by a considerable margin.

The DPRK is a nuclear armed buffer state and shall remain so for the forseeable future.
