I keep telling my American friends, "If you think of Donald Trump as only something that is happening inside the United States, you're missing it." Because there are Trump-like events happening across the Western world, in Warsaw Pact countries, in France, Germany, Austria, the Netherlands. As we speak, the second-largest party in the Dutch legislature - who's more level-headed than the Dutch? - is Geert Wilders's party, which is a very Trump-like party, and they've got 33 out of 150 seats.

No one is murdered in Hungary and there are no illegal arrests, but people have begun again, when they talk to you in a public place looking around to see who's listening. You see that in Slovakia, you're beginning to see that in Poland.

By abrogating all moral standards in their war against Israel, Arab and Muslim leaders initiated a process of moral collapse that has ended by soaking their own societies in blood. The terror they intended to inflict only upon others has rebounded with a hundred times greater horror upon their own lands.

One might almost say, to adapt von Clausewitz, that modern warfare is PR by other means. And war-winning strategies mean that modern armies most stop treating their communications operations as secondary assignments or (as still too often happens) dumping grounds for officers who have failed at everything else - but as missions absolutely essential to success.

The big winners under the American fiscal system are the rich, who pay some of the lowest taxes anywhere in the world; the old, who are the main beneficiaries of the American social service state; farmers, rural people. These are Republican constituencies.

Elites are inevitable in politics. That is how politics is going to work. The question is, are your elites responsible, public-spirited? Do they think about the interests of others, not just themselves? And the story of Western politics since the beginning of the century is that as elites become more separated, more selfish, as they leave behind their populations and don't think about them, they become discredited. And the people look for alternatives. But the alternative is worse. Those rules of the game protect us all. And they are more precious than almost any political outcome.

One of the great drivers of the alienation that has made Donald Trump possible is that the growth in the American economy has been weak. In the decade from 2005 to 2015, there was not one year when the US hit three per cent growth. And to the extent there's been growth, virtually all of it has been collected by the top 10 per cent of the population. Obviously, if we knew how to make growth faster, we would. We don't. And it's very difficult to make growth more broadly shared. Because it's not just the US that has this problem.
