I believe democracy can survive. But it's certainly true that the euphoria of the 1990s - an era when democracy was spreading and more and more people found it attractive - has ended. Trump is not a cause but rather a symptom of this change.

The old battle between Christian Democrats and Social Democrats is now meaningless, not least because the social structures that underlay those parties, the church and the unions, have faded away. Nationalists and populists understood this change earlier; now the rest of the political world needs to understand that the political lines have been redrawn and it's time to change.

Putin discovered that when he invaded Ukraine, he expected the Ukrainians to rise up and join him and say, "Yes, we want to be part of Russia," and that didn't happen. And they've been paying, actually, I think quite a high price for it, both in the ongoing war in Ukraine - which is I think increasingly unpopular in Russia - and also in the Western sanctions, and in general, the separation from the West that was caused by that.

Americans have long felt that NATO isn't doing its job and that the Europeans aren't contributing enough. Trump has accelerated the decline in Atlantic solidarity by offering open contempt for NATO allies as well. The future of NATO now very much depends on Europeans. Can you begin to identify security threats, prepare yourselves and arm yourselves without the US?

I have been told by people close to Trump that "Brexit Britain" is the only foreign policy issue that interests him, because he thinks the UK referendum paved the way for him. He hopes to help Britain leave the EU, and possibly to damage the EU, by offering a trade deal.

We may be reaching the end of the liberal world order.
