Abstract
Some recent views question the concept of sovereignty (especially the sovereignty of states), arguing that sovereignty is to be abandoned as a historical concept, because it existed in the world of the Westphalian system (created after 1648), where states were the major players, centers of power and objects of interest. Instead, we suggest that sovereignty should be perceived again as a “supreme power” (summa potestas), meaning a return to the pre-Bodinian concept of sovereignty and perceive it as a “power to exert control”. With regard to cyberspace, this does not mean direct control of all entities in the cyberspace, but only those that provide services which are perceived as “essential” or “critical” for the security and interests of the state. That is actually the approach taken with regard to ensuring the safety of 5G networks—through control imposed on the network operators, as required by the respective EU legislation and the EU Toolbox on 5G Networks specifically.
