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.

I don't want to predict calamity. But I am afraid of a new Russian occupation of parts of Eastern Europe. Also of a new Russian campaign to exert influence in Germany or other parts Europe, aimed at making continental politics less democratic. I am afraid of a US trade war and even a shooting war with China.

Putin is not a mass murderer. But, having said that, he is a product of the KGB, and the KGB was, of course, the secret police force of the Soviet Union.

Donald Trump has never tried to reach out to all the American people, he never uses the language of unity, he doesn't try to charm or persuade. He just says, thanks to the people who voted for me and the rest of you are losers.

The surge in right-wing populism and the phenomenon of Trump are related. You can think of them together as the same problem.

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.

Trump has learned how to function in a world in which people now live in very separate realities, where they get their news from Facebook recommendations and believe in a particular set of facts. Others, who live in a different reality, know quite a different set of facts.
