The election of Donald Trump is a symptom of a general crisis in international liberal order. Its costs have been seriously underestimated: relocations breaking the social contract, the poor assimilation of migratory flows by societies, divisions between the elites and the masses (the so-called “losers” of globalisation), electoral and political crises. Societies should adapt the liberal order to their deep-rooted characteristics rather than accept it as a global and necessary reality.
