A week on from my declaration that I’m giving up politics, my mind has settled a little more, and I realise more fully what I meant by that. I remain interested — fascinated, even — by fundamentals: what you might call political philosophy. What I have no time for or patience with is current affairs: the specific set of events and personalities that are in the news right now. That stuff is both ephemeral and monumentally frustrating, so best ignored. But the core issues continue to exercise me.
So when should we use a nuclear deterrent?
