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.

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.

Most of the people buying the Soviet paraphernalia were Americans and West Europeans. All would be sickened by the thought of wearing a swastika. None objected, however, to wearing the hammer and sickle on a T-shirt or a hat. It was a minor observation, but sometimes, it is through just such minor observations that a cultural mood is best observed. For here, the lesson could not have been clearer: while the symbol of one mass murder fills us with horror, the symbol of another mass murder makes us laugh.

European security may now depend on Germany, France, Britain and one or two others, and it's better to start planning now for the possibility of European-only cyber-defense, counter-terrorism, and conventional defense too.

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 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.

Steve Bannon, the White House chief strategist, appears to imagine an alliance between Trump, Le Pen, Geert Wilders and Nigel Farage. Call it the populist international, a fraternal association of the nationalist right, binding people who want borders, across borders.
