1. Does NK even have the capability to pull something like this off? They seemingly fail at every other intimidation stunt they pull off & now they have a massive success out of nowhere? Hm...
2. Why would they deny it if they did it? It's very out of character for them to not pounce on the chance of something being very embarrassing to the US.
3. With all the talk of it being so complicated to pinpoint exactly where the attacks came from, what info is the US gov using to pin this on NK (besides the very easy narrative around the context of the movie). They have to have a bit more intel than they're letting on...or something is fishy here.
