The Russian economy is about the size of the Italian economy; it's very small, and Russia's military force is larger than it was, because Putin's been investing in it, but it still doesn't compare to that of the United States, and his reach and aim still don't compare.

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

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.

We can't continue assuming that politics is something which is decided elsewhere by distant leaders in a distant capital. Protest is insufficient too. If people who are willing to put time into demonstrations also prove willing to work on behalf of candidates in local elections - or to become candidates themselves - they will achieve far more. If all of this upheaval provokes more involvement, then we have a slim chance of ending up with more vibrant democracies eventually. The alternative, as you've hinted, is that democracy fails altogether.

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.

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?

Americans have long felt that NATO isn't doing its job and that the Europeans aren't contributing enough. Trump has accelerated the decline in Atlantic solidarity by offering open contempt for NATO allies as well. The future of NATO now very much depends on Europeans. Can you begin to identify security threats, prepare yourselves and arm yourselves without the US?
