What do you think society would be in 2020?

No balance of power lasts forever. Just a century ago, London was the centre of the world. Britain bestrode the world like a colossus and only those with strong nerves (or weak judgment) dared challenge the Pax Britannica.

That, of course, is all history, but the Pax Americana that has taken shape since 1989 is just as vulnerable to historical change. In the 1910s, the rising power and wealth of Germany and America splintered the Pax Britannica; in the 2010s, east Asia will do the same to the Pax Americana.

The 21st century will see technological change on an astonishing scale. It may even transform what it means to be human. But in the short term – the next 20 years – the world will still be dominated by the doings of nation-states and the central issue will be the rise of the east.

By 2030, the world will be more complicated, divided between a broad American sphere of influence in Europe, the Middle East and south Asia, and a Chinese sphere in east Asia and Africa. Even within its own sphere, the US will face new challenges from former peripheries. The large, educated populations of Poland, Turkey, Brazil and their neighbours will come into their own and Russia will continue its revival.
