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.

Think of the French presidential candidate Emmanuel Macron, Ciudadanos in Spain, Nowoczesna in Poland. These are early efforts to reimagine a liberalism which is neither right-wing nor left-wing in the traditional sense.

We can't continue assuming that politics is something which is decided elsewhere by distant leaders in a distant capital. Protest is insufficient too. If people who are willing to put time into demonstrations also prove willing to work on behalf of candidates in local elections - or to become candidates themselves - they will achieve far more. If all of this upheaval provokes more involvement, then we have a slim chance of ending up with more vibrant democracies eventually. The alternative, as you've hinted, is that democracy fails altogether.

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?

Navalny is a blogger-turned-activist, but he finds stuff and he puts together these very, very clever, very high production value videos which underline the corruption at the top of the system, and there are millions of people who watch them. Some people think he must have some kind of protection inside the system because he hasn't yet been completely put out of commission; he's allowed to go on. He himself has said he wants to run for president.

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.

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.
