The world has always been a dangerous place. Now it is dangerous in a different way, because the world order that we've known since the end of the Cold War has been radically transformed. All of the institutions that preserved peace and promoted global trade will be weaker - NATO, the EU, NAFTA - and US relationships with other countries will change, too.

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.

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 don't think Americans realize the degree to which they are the main subject of Russian television news. Every night there's news from the United States and scandals about the United States, and every night the United States is shown to be an enemy of Russia over and over and over again. And this is, of course, useful to the Russian president, because it's, we have this big and important enemy - you need me here to fight back.

What's interesting about Navalny is that he has run a - not so much a pro-democracy campaign in Russia, but an anti-corruption campaign. He seems to have access to quite a lot of information about very senior Russians, including Putin.

I didn't like doing predictions. It's certainly true that right now - and this could change tomorrow - but, right now there is no clear way for Putin to lose power. There seems little chance that a street revolution could unseat him; that's just not how things are going to work in Russia. And it seems as if the very tiny number of people who control the economy and who control politics in Russia are loyal to him.

What is the appeal of Trump, really? It's nostalgic: "Make America great again." Like European nationalists, he has a vision of a "real" America, one which predates globalization, immigration, feminism, the civil rights movement and technological change, an imaginary 1950s to which we can now return. That is actually not very different from the kind of language that Marine Le Pen uses, or parts of the Brexit movement.
