The end of the Cold War has profoundly transformed Europe’s security situation. Although traditional security issues remain important, the most immediate threats to security since 1989 have originated not from relations between states, but from instability and conflict within states that has threatened to spill over into the interstate arena. States’ efforts to shape and control this new security environment have resulted in a unique hybrid arrangement containing elements of traditional alliances, great power concerts, state and community building, and collective security.
