It wouldn't surprise me if his team were behind the intelligence leaks (lol) to divert attention away from his clearly conflicting business 'restructure'.
In terms of him being an imbecile, I'm still undecided. I think he's got the face of a liar. Whatever he says, his delivery makes him look to me like he's blagging it. I've interviewed and managed people that use his body language (I inherited the ones I managed, I didn't hire them!) and it looks chillingly familiar. I don't think him getting into power is any proof of his genius though - or at least his lack of imbecility.
You'd hardly think David and Victoria Beckham were top of the class, but by being surrounded by the right people, and cultivating a persona, they've become incredibly wealthy and powerful. Perhaps in the modern world, that's all the smarts you need.
