2 Journalists are first, but everyone else is next. Trump has announced multibillion-dollar lawsuits against “the enemy camp”: newspapers and publishers. His proposed FBI director is on record as wanting to prosecute certain journalists. Journalists, publishers, writers, academics are always in the first wave. Doctors, teachers, accountants will be next. Authoritarianism is as predictable as a Swiss train. It’s already later than you think.

5 You have more power than you think. We’re supposed to feel powerless. That’s the strategy. But we’re not. If you’re a US institution or organisation, form an emergency committee. Bring in experts. Learn from people who have lived under authoritarianism. Ask advice.

7 Know who you are. This list is a homage to Yale historian, Timothy Snyder. His On Tyranny, published in 2017, is the essential guide to the age of authoritarianism. His first command, “Do not obey in advance”, is what has been ringing, like tinnitus, in my ears ever since the Washington Post refused to endorse Kamala Harris. In some weird celestial stroke of luck, he calls me as I’m writing this and I ask for his updated advice: “Know what you stand for and what you think is good.”

10 Listen to women of colour. Everything bad that happened on the internet happened to them first. The history of technology is that it is only when it affects white men that it’s considered a problem. Look at how technology is already being used to profile and target immigrants. Know that you’re next.

15 Remember. Writer Rebecca Solnit, an essential US liberal voice, emails: “If they try to normalize, let us try to denormalize. Let us hold on to facts, truths, values, norms, arrangements that are going to be under siege. Let us not forget what happened and why.”
