The evolution of a bourgeoisie is a healthy phenomenon when it grows and prospers thanks to bourgeois values: hard work, honesty, personal responsibility.

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.

If Putin decides to run, which we are assuming that he will, there really isn't anything that can stop him. He can manipulate the system so that he has not real opponents; he can manipulate the media so that nobody else gets any coverage. And then, if worse comes to worse, he can - as he has done in the past - just change the electoral results. So, it's not like it's going to be a very exciting election.

The world has always been a dangerous place. Now it is dangerous in a different way, because the world order that we've known since the end of the Cold War has been radically transformed. All of the institutions that preserved peace and promoted global trade will be weaker - NATO, the EU, NAFTA - and US relationships with other countries will change, too.

Navalny is a blogger-turned-activist, but he finds stuff and he puts together these very, very clever, very high production value videos which underline the corruption at the top of the system, and there are millions of people who watch them. Some people think he must have some kind of protection inside the system because he hasn't yet been completely put out of commission; he's allowed to go on. He himself has said he wants to run for president.

Putin imagined it would be different. So, like many Russian leaders before him, he imagined that Ukraine was basically Russia, but they speak with a funny accent. Actually, it's not Russia; it has a different identity. It has a very different language. Russians don't automatically understand Ukrainian. And, in particular, the way Ukraine has developed over the last two decades is different from the way Russia has developed.

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?
