FBI sort of thinks they did it, but then again, lots of people think they didn't. I don't think it helps that North Korea's message seems a bit mixed on the matter; they didn't do it, but if the US retaliates, then it is on like Donkey Kong! (Against "the whole US mainland"--so, like, Hawaii should feel pretty secure from one of NK's sturdy Aquatic Annoyance Devices.) Seems kind of defensive to me.
So I also don't know what to make of the situation where North Korea's internet went down. I mean, really, is there any good reason to think the US directly participated in an attack on that nation's information infrastructure? (Maybe they should just ring their provider or something.) Is that how the US rolls?
I still think it's weird to imagine that this is all over a comedy movie that might even be a bit of a bow-wow. But it looks like the young dictator is still consolidating power, so killing the odd army minister or uncle or religious proselytizers, or even people who watched soap operas, is just how he validates who is really in charge. So it really doesn't do for him to be lampooned in a movie that will probably somehow still be pirated and watched in North Korea anyway. (I think I like the idea, a little, myself.) In the world of a dictator (whose father was a noted cinephile and probably a very, shall we say, dominating influence on him?) trying very hard to grasp and hold the reins of power, something like a movie that doesn't cast him in the best of lights seems far more significant to him than it might to people in a culture where our elected leaders are regularly shredded in the press and television programs.
It's cheap, of course, to malign North Korea's ruler in a comedic vehicle. His regime is associated with the tactics of starvation, imprisonment, labor camps, rape, and torture. The people of North Korea are suffering under a yoke that is anything but comedy gold. It's actually appalling. And there's only so much any of us can do about it, either.
Except to point out that Kim's Macklemore haircut really isn't as face-slimming as he thinks it is.
