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.

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.

Unlike most European countries, the police in the US are decentralized; even the FBI has regional offices. Amending the constitution is a long and tedious process.

The Soviet Union was, by the 1970s and 1980s, relatively stable and predictable. Putin's Russia is much more volatile. Nuclear policy is really in the hands of one person, or a small group of people, instead of a huge party-state apparatus. The possibility of a mistake is greater now.

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

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?
