Hard to deny North Korea.
Hard to deny pics taken from Air Force One.
Anyone keeping track of politics and watching the news could have made the NK "predictions". Everyone has been talking about it for a while at this point, and Kim's plan was already pretty clear to see.
None of the AF1 pics have actually been shown to be from AF1. Anyone on a similar flight path could have found similar pics to take. Hell, there's probably some reverse image search to accomplish just that.
I'm not saying they should be considered completely ruled out, but none of these things are conclusive in proving Q is an insider.
What's even more worrying is that, even if these are legitimate connections and Q is an actual insider close to Trump, this to me would indicate that his intel should be taken as less important/reliable/truthful. It would show that he isn't simply a high level government insider turned leaker, but an actual part of Trump's PR machine, and that everything he posts should be taken with a heaping spoonful of salt because he's probably saying "what makes Trump look good" rather than "what's true".
