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.

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.

I didn't like doing predictions. It's certainly true that right now - and this could change tomorrow - but, right now there is no clear way for Putin to lose power. There seems little chance that a street revolution could unseat him; that's just not how things are going to work in Russia. And it seems as if the very tiny number of people who control the economy and who control politics in Russia are loyal to 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.

I don't think Vladimir Putin and Donald Trump really have friends. But Trump has openly admired Putin for many years, with no reservations. He even seems to idolize him. Neither his cabinet appointees nor the civil servants in the Pentagon and the State Department feel the same way, however, so we don't know what this admiration will bring.

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.
