In this chapter, a study is carried out in which the existing difficulties in establishing clear and forceful leadership in both cyberspace and the international system are evidenced, appealing to the theory of realism of the discipline of international relations and the study of threats and new forms of conflict.Certainly, the conjunction of economic, political and geostrategic interests has marked the dynamics in various dimensions at the national, regional and international levels, so it will be observed how this prevents some from eventually accumulating power resources in defined periods, but without genuinely establishing a leadership process.Finally, it addresses how cyberspace is analyzed as the preferred scenario of new forms of conflict, and how cyberspace power is not limited to the exclusive use of a nation's Military Forces but can be exercised by a large number of actors with the technical and human capacity for their own convenience in the cyber domain, which could force States to rethink the design of their national security and defense strategies.
