I have the mildest of manners. But as soon as someone tilts their seat back even an inch murder becomes a priority. If a baby makes baby noises, I think of Joan Rivers (‘is there a terrorist on board? I’m willing to help’). And if there really is a terrorist on board, forget it. I would rather die than go on trying to eat a sausage out of a paper cup with a spork.

But “concentration camp” is the only possible definition of Fort Sill, a place that was used during the Second World War to cage those Americans who looked (subversively) Japanese. It had been closed as of 2014. But there is no achievement of the last administration so minor that it cannot be undone, and the camp will now open again, this time to intern children, seekers of asylum from the hysteria of gang violence in El Salvador, Honduras, and Guatemala.
