The concept has not become a mainstream term in the field of international security despite its long history. After the end of the Cold War, the concept of a security community was adapted by constructivist scholars. A major impetus was the book "Security Communities" (1998), edited by Emanuel Adler and Michael Barnett. They redefined the security community by shared identities, values, and meanings; many-sided direct interactions; and reciprocal long-term interest. Several regions of the world have been studied in the security community framework since then, most notably the European Union, the Canada–United States and Mexico–United States dyads, Mercosur, and Association of South East Asian Nations (ASEAN). Michael Haas compared the Asian and Pacific Council, Asian-Pacific Parliamentarians Union, ASEAN, Indochinese Foreign Ministers Conference, South Asian Association for Regional Cooperation, Southeast Asia Treaty Organization, and the South Pacific Forum (later renamed the Pacific Islands Forum).
