Trump has learned how to function in a world in which people now live in very separate realities, where they get their news from Facebook recommendations and believe in a particular set of facts. Others, who live in a different reality, know quite a different set of facts.

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.

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.

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.

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.

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

I don't think Americans realize the degree to which they are the main subject of Russian television news. Every night there's news from the United States and scandals about the United States, and every night the United States is shown to be an enemy of Russia over and over and over again. And this is, of course, useful to the Russian president, because it's, we have this big and important enemy - you need me here to fight back.
