Globalization is associated with a new regime of sovereignty as a result of the emergence of some new forms of non-territorial economic and political organization in the global field. Such a reality transforms the state into an interface between the global system constantly shaped by the forces of globalization (especially economic) and the substatal system mainly characterized by the decentralization of power. First, nation-states have functionally become parts of a vaster pattern of global changes and, second, the idea of global politics underlines the complexity of the interpenetrations that transcend states and societies, adding to them a large network of agencies and organizations. Within such an anarchical context the predictability of these interactions may be analyzed through the perspective which reflects the intensification of the global and regional engaging patterns. In such a context, from a constructivist perspective, the study tries to underscore the way the state is shaped by the global transformations and, at the same time, the way the state is transforming itself under the pressure of such challenges. So, I will underline the shift from globalization to fragmentation as a reflection of political costs mediated by the state: sometimes, globalization changed the accent from the domestic sectors; on other times, the domestic interests had priority and so the result was international fragmentation.
