Donald Trump may undermine some of the traditional checks on the presidency: the press in particular, but also the various government and Congressional ethics bodies, as well as the career civil service.

Putin has made life difficult for a lot of Russia's richest men; they don't like the sanctions; they don't like the war with the West. Many of them have houses and families and businesses in the West, and so I can see them being unhappy. But at the moment, the political system is so constructed that it would be very difficult for them to leave. That's not saying it couldn't change.

The nationalist right have common views. They hate the EU, they hate NATO, they dislike trade, they admire Russia. Many of them are funded by Putin.

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.

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.

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.

nothing happens in August - except when something really happens in August. World War I began in August, Saddam Hussein's invasion of Kuwait began in August, al Qaida was preparing to bring down the World Trade Center in August. August, in other words, is the time when all of us should prepare our backup plans, chart our reversals of course, [and] think through possible paradigm changes.
