Despite its excesses and contradictions, globalization has lifted billions of people out of poverty, enabled scientific progress, and reduced conflict. Nevertheless, globalization is going through a deep crisis. Marco Magnani identifies four forces that are fueling the « great disconnect» : economic and technological trends are reshaping global value chains; do-mestic political dynamics are fostering closures in an attempt to protect national interests; external shocks (pandemics, wars, financial crises) are exposing the vulnerability of the global system; geopolitical objectives are encouraging to restrict relations to countries perceived as friends. In such a scenario, politics prevails over economics, regionalization increases, and the instability of international alliances soars, partly due to the proliferation of « free agent» countries seeking strategic autonomy. Fragmentation has high economic costs and it increases the risk of conflict. But it may also trigger a new globalization trend. The Arctic, the Under-water, Space and the Digital Revolution can be fronts of competition and dispute, or they can represent the new frontiers of cooperation.
