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.

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.

Putin saw the Ukrainian revolution as a challenge to him personally, and I think that's why he, in fact, over-reacted. I think his occupation of Crimea and then annexation for him was actually a mistake from Russia's point of view. And then his invasion of Eastern Ukraine was also a mistake. He imagined that he would invade Eastern Ukraine and then eventually split the country in half, and he discovered that in fact, Russian-speaking Ukrainians are not Russians, and they didn't support him.

The Soviet Union was, by the 1970s and 1980s, relatively stable and predictable. Putin's Russia is much more volatile. Nuclear policy is really in the hands of one person, or a small group of people, instead of a huge party-state apparatus. The possibility of a mistake is greater now.

The evolution of a bourgeoisie is a healthy phenomenon when it grows and prospers thanks to bourgeois values: hard work, honesty, personal responsibility.

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.

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.
