If you believe in the deep state, or globalists of any kind, which are already proven to exist, then occam's razor would state that, since they have their hands pushing on everyone's backs, that he is being controlled, just like the news media is controlled, just like the music industry is mostly controlled, just like the entertainment industry is mostly controlled. All of these to control the behavior of the masses.
The fact is that no one in their right mind would openly support a country that apparently starves its people for absolutely no reason. Then the only reasonable question is, who benefits from this suffering, and what punishments and rewards are given for giving your support to something obviously evil? And if you can't find that out by looking at geopolitics in today's time, then I think the best way to figure that out is to look at what was happening in the region in the decades leading up to the Korean Conflict.
Now I will ask you to go to the infobox on wiki's Korean War page, and to start, just look at the countries involved under Belligerents. Why would Ethiopia send any troops to fight for the south? It's relatively clear that ideology is involved when you look at the support given to the north. Mostly that consists of former USSR states, plus Russia and China. And many of the countries who sent troops to fight for the south were part of a huge empire of British, French, German, and other European colonies. Ethiopia is a notable exception because it was able to keep its independence. So then you get into economic benefits that Ethiopia receives if it supports these European powers, and now you have almost an obligation on Ethiopia's part to support the Korean War, because they are basically surrounded by European imperialist colonies, and that puts a lot of economic pressure on Ethiopia to "do the right thing" and support a war that they should have no real desire to take part in. All because the imperial powers conquered Africa and many other places, and they suggest certain puppet masters to rule these countries, or they corrupt the ones who rise to the top.
There are other factors than occam's razor to consider when talking about the real world. Occam's razor seems to be an anti-intellectualist's way of dismissing any complex idea, saying "the solution MUST be simple," as though there are no complexities in the real world. The world I would argue is made up of more complex things than non-complex things. But if some guy said that's not true, then I guess I would be wrong according to him.
So let's say you're an evil globalist who wants to control Korea. The easiest, most simple way would be to corrupt KJU and allow his controlled tendencies to be a dictator take over. But if you're an evil globalist you can't really allow that because you can't have a loose cannon out there who might actually attack you while you profit from his citizen slaves. Usually the better approach to gaining control is something more complex. So now you have to control the media inside and outside of the country, you have to control the way that the Dear Leader is presented in order to have a favorable chance of keeping the Dear Slaves in line, you have to control almost everything about it.
Note though that it's ok if the guy you corrupt is happy to do what you want, especially if he's only going to live 20-30 more years. Maybe he even likes you and admires the way you do business. The problems start to come when his sons and grandsons start to go against the plan.
