I know we live in a time when so many upsetting things happen in just one week that it’s easy to forget individual incidents. But I would like to remind you of one sentence – which we should not forget so quickly. Just over a week ago, Donald Trump, the President of the United States, posted: “An entire civilization will die today and never return.” He was referring to Iran. We have to talk about these words again: because there is a danger that we are all currently part of a shift in norms.
