The world, meanwhile, is remorselessly becoming an integrated global economy. It is beyond any man's mortal power to stop the trade that can now be done across border by the internet, the sourcing of goods from places were they are made most efficiently and the attraction of investment to poor countries with the potential to be rich.
Agreeing on a code of international law to govern globalisation will always be difficult. The nation state is not in decline. Rather it is Europe's hopeful post-war project to supersede nationalism that has taken a backward step in 2016. Britain might not be the only member to leave the European Union in the next few years.
The US election, too, was a re-assertion of nationalism, not just in economics and trade but in culture and ethnicity. Many have taken fright at the scale of migration in the modern, more integrated world.
But threats from migration have been overstated and the benefits not acknowledged by demagogues who have succeeded in politics this year. Migration is needed by most developed countries with ageing populations and birth rates below replacement level.
More important, migration enriches the receiving countries economically and culturally. Life is more better for the variety of skills, tastes and interests migrants bring.
Democracies have succumbed to fear this year because of terrorism from the Muslim world. Even the US, facing a fraction of the numbers pressing on the EU's borders, has been unnerved.
But fear is not humanity's natural state. We are an optimistic species and progress will prevail.
