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.

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.

We may be reaching the end of the liberal world order.

Globalization has genuinely drained power away from national politicians and people feel it. People in our fast digital age are also frustrated with the comparably slow democratic processes. Many young people - and some old people - want to know, Why does everything take so long? Why can't someone just decide and then move forward?

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.
