Johnson is exactly like me in one respect in that he strikes me as having a habit of reading a few pages of an instruction manual, text book, explanation of the circumstances behind an event and thinking he knows all there is to know on the subject. It's a bad habit for someone like me to have, but, in truth, the only person I tend to damage when it happens is myself - it's a bit different when you're a Foreign Secretary with all too obvious designs on the top job.
