The trouble is, people still don’t talk about it the way they talk about Hungary, not inside the US and not outside it. That’s partly the It Can’t Happen Here mindset, partly a reluctance to accept a reality that would require, of foreign governments especially, a rethink of almost everything. If the US is on its way to autocracy, in a condition scholars might call “unconsolidated authoritarianism”, then that changes Britain’s entire strategic position, its place in the world, which for 80 years has been predicated on the notion of a west led by a stable, democratic US. The same goes for the EU. Far easier to carry on, either pretending that the transformation of the US is not, in fact, as severe as it is, or that normal service will resume shortly. But the world’s leaders, like US citizens, cannot ignore the evidence indefinitely. To adapt the title of that long-ago novel, it can happen here – and it is.
