"He's smaller because of famine" "communism no food"
I checked out the Wikipedia article for the famine because it's the easiest source to find and it is full of brainworms of course. But if you read between the lines it was first and foremost caused by material circumstances. North Korea simply cannot grow enough food to sustain itself. If you then suffer horrendous floods and the fall of your most important trading partner you get a famine. That is without including the sanctions and the catastrophic war that happened a few decades earlier.
Also it's pure propaganda, let's find our meat mountains to stand beside the North Korean for a photo op.
This is a good example of how sophisticated and effective the propaganda of western capital is. You don't even need to pay operatives to create and proliferate it. You just stage it, let the media cycle take it and run with it, and let the consent manufacture itself.
