Europe is sleepwalking into oblivion, and the people of Europe need to wake up before it is too late. If they don't, the European Union will go the way of the Soviet Union in 1991. Neither our leaders nor ordinary citizens seem to understand that we are experiencing a revolutionary moment, that the range of possibilities is very broad, and that the eventual outcome is thus highly uncertain.

Most of us assume that the future will more or less resemble the present, but this is not necessarily so. In a long and eventful life, I have witnessed many periods of what I call radical disequilibrium. We are living in such a period today.

The next inflection point will be the elections for the European Parliament in May 2019. Unfortunately, anti-European forces will enjoy a competitive advantage in the balloting. There are several reasons for this, including the outdated party system that prevails in most European countries, the practical impossibility of treaty change, and the lack of legal tools for disciplining member states that violate the principles on which the European Union was founded. The EU can impose the acquis communautaire (the body of European Union law) on applicant countries, but lacks sufficient capacity to enforce member states' compliance.

The antiquated party system hampers those who want to preserve the values on which the EU was founded, but helps those who want to replace those values with something radically different. This is true in individual countries and even more so in trans-European alliances.

The party system of individual states reflects the divisions that mattered in the nineteenth and twentieth centuries, such as the conflict between capital and labor. But the cleavage that matters most today is between pro- and anti-European forces.

The EU's dominant country is Germany, and the dominant political alliance in Germany – between the Christian Democratic Union (CDU) and the Bavaria-based Christian Social Union (CSU) – has become unsustainable. The alliance worked as long as there was no significant party in Bavaria to the right of the CSU. That changed with the rise of the extremist Alternative für Deutschland(AfD). In last September's länder elections, the CSU's result was its worst in over six decades, and the AfD entered the Bavarian Parliament for the first time.
