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.

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.

A lot of the Russian economy is built around people who are one way or another milking the state and taking money from the state and recycling it into their private bank accounts. And there are a lot of people who are taking advantage of that, so it's not just one person. It's a kind of web of people doing that, and that's how the system stays in power and how people stay in control.

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.

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.

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.

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.
