The changing concept of security in international relations

الملخص EN

Security has meant very different things to people depending on their time and place in human history.

the traditional notion of security, as a reference to national survival, physical protection of state territory, and military power has expended its scope in the second half of the 20th century, particularly since the end of the Cold War.

This was associated with development within the academic mainstream of security re-conceptualization and re-theorization what let to the emergence of the current approaches in security studies such as the Copenhagen school and the approach of the asymmetric threat.
