The world has entered a period where uncertainty rules and where surprises abound.

Focusing on 2016, the two major surprises usually singled out are the Brexit or the vote leading to the exit of the U.K. from the European Union, then the election of U.S. President Trump against favourite Democratic candidate Hillary Clinton. Even though a short-term focus could let us believe that the turmoil only or mainly hits “the West”, political and geopolitical surprises and uncertainties have multiplied worldwide, starting at least with the shock of the financial crisis in 2007 and 2008 and responses to it (see end note for some major instances*).

What is thus happening? How are we to tackle the uncertainty? Are these surprises related or discrete independent events that it would be wrong to link or try to understand together?

We shall start here with the 2016 surprises and related ongoing uncertainty, i.e. the Brexit and the U.S. Trump Presidency, and focus more particularly on the contradictions and questions that arise when we compare the two phenomena. We shall seek a framework for and elements of understanding, which can then be used in the development of scenarios for the future.
