I once wrote a long article about a Korean War II.
But this one chart tells essentually the same tale.
I suspect it will be a harder nut to crack than Iraq in 2003, or even 1991. It is an ultranationalist (not a Communist) regime with a formidable secret police, so you’re not going to be buying any generals off. North Koreans have higher IQs than Iraqis (so more competent), do not practice inbreeding (so more cohesive), and a have a lot more hills, mountains, and tunnels (which partially negate South Korean/American technological predominance).
Still, the gap is too vast for the ultimate result to be in doubt. (Unless China gets involved. Then things get complicated.)
And this is why it’s isn’t going to happen.
I do think that Kim Jong Un enjoys the good life, as do the elites he’s fostered in Pyongyang the past decade – according to Andrey Lankov, one of the foremost experts on North Korea, living standards are now far higher than during the grim 1980s or the dismal 1990s – and would prefer to keep things that way. If there is a limited strike on Nork nuclear facilities in the coming days, I doubt we will see anything more substantial than outraged rhetoric.
China will probably be just fine with that. There is very little love lost between Kim Jong Un and the current Chinese leadership. Xi Jinping recently noted that whereas his father had visited China four times, the son had yet to do so, which is a rather open criticism by demure Chinese standards. This was understandable, since Kim Jong Un has spent the last few years suppressing pro-Chinese factions in his country, including members of his own family (executed uncle, assassinated half brother). I suspect the Chinese are fine with Kim Jong Un receiving a demonstrative slapdown, and wouldn’t mind seeing his nuclear program set back a few years. After all, Beijing is considerably closer to Pyongyang than is Tokyo, to say nothing of Honolulu, and there is no telling what North Korea would do in a truly serious future crisis.
Why not get Donald “I Make the Best Deals” Trump to give Kim Jong Un a good beating, especially when he’s also offering to throw in some excellent trade deals for free. It’s a bargain!
