Society is undergoing fundamental transformations because of the rise of new forms of governmentality in the Western world. The transnational is blurring the distinction between the internal and external, and destabilising related concepts: sovereignty, territoriality, security (Badie 1995). Sovereignty is meaningless and must be adjusted to the processes of European construction and economic globalisation. The notion of borders is fading away, as is the old notion of lines or fronts. In its place are boundaries and regions, (NAFTA, 'Schengenland') and the concept of security must be adapted accordingly to take account of these changes. The transnationalisation of security opposes national (and societal) security. It creates, as in a Möbius ribbon, a situation where one never knows whether one is inside è or outside (Bigo 1999; Walker 1993).
