Killing tyrants, real and imaginary is fair game. If it was the Italian Prime Minister or another ally or country in good standing, I would agree. N Korea is fair game.
While I understand where you are coming from tGoFP, I do think North Korea is such a pariah nation, that it opens itself up to this type of subject matter.
All the guy has to do is moderate, treat his populace like human beings, and nobody would be creating this sort of media focused on him.
Perhaps it’s a decent way to let the a..h... know what the rest of the world thinks of him.
I don’t think the U. S. is alone in what it thinks of him either. This will sell in other nations as well as in the U. S.
