In the 1970s, the concept of security was still strongly connected to territoriality and to a locally-based perception of emergency. The national-international nexus, shaped by the bipolarity of the Cold War, inevitably affected the perception of security in terms of what was recognized as existing inside and outside of the national sovereignty sphere. Over this decade, the definition of political opponents, state borders, territory and national sovereignty in Europe underwent a new attribution of meaning. Political armed violence made its first appearance, for example, as Europe had known only street riots and sporadic social conflicts until then. The international dimension taken on by armed political violence by the end of the 1960s challenged governments and security apparatuses to rethink their theoretical and logistical approaches to terrorist emergency on foreign soil.
