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.

To describe Russian politics as "managed democracy" - and that's sometimes hard for outsiders to understand, because a lot of the forms of democracy exist in Russia, so there are elections; there is a press; there is a campaign, and so on. But the outcome of the campaign is never in doubt. So the campaign is manipulated. There is a real opposition in Russia. There are one or two real opposition figures who do want to change the political system, but they will probably not be allowed to run, and one way or another they will be prevented from being on the ballot.

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.

Though the poorest Americans voted for Hillary Clinton, many relatively wealthy people voted for Trump and generally it's a mistake to think that economics explains Trump. The US is doing relatively well, the economy has significantly recovered since 2008, unemployment rates are low. I would say rather that his appeal to the working class was cultural: "I'll bring back the kinds of jobs your fathers had," and, by implication, the whiter, simpler post-war world when America had no real economic competition.

Khodorkovsky is richest man. And he lost everything when Putin arrested him and took his company away, and essentially took his company away, sold it, and gave it to other people, and enriched them. So, he's a complicated figure as an opposition leader, and people admire him - he was in prison, and he was very brave, and he's written some good things since then, and so on. But at the end of the day, people see him as being part of the corrupt system that has done so much to undermine the Russian system since the 1990s, and I don't know that he can ever be a really popular leader.

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.

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.
