The Copenhagen school constitutes the most coordinated approach to study security in the constructivist tradition as explained by Williams (2008). It states that security is created in a process known as securitization and is not a fixed unit. In a study, scholars found the definition of security as issues that are staged as threats to referent objects by securitizing an actor an actor thereby generating emergency measures beyond binding rules. The scholars suggested that security studies be taken beyond a limited agenda that focuses on the military relations between states while avoiding inflating the concept. They concluded that at various levels of analysis special threats justify the use extraordinary measures.
Regional security complexes develop and they can be explained as groups of units whose security dynamics and processes are connected that security issues cannot be reasonably resolved and analyzed from each other as explained by Buzan (2003). These complexes can be defined in exclusive geographical regions with the focus being on the security dynamics and interaction between all the continents of the world. The conclusion is that the regional security level is gaining importance for global security dynamics however the theory has been poorly formulated. The major contribution of the Copenhagen School is the securitization concept while considering all other key ideas for the approach at the organization level. Regional security complexes are important for the framework as sites for securitization practices or as dynamic determining the success or failure of the practices in certain geographical locations.
Securitisation is the response to the identification of new security threats can be defined as the basis of the Copenhagen School of conflict studies. The approach concerns expansion of the idea while retaining the specific character of security problems. Issues that are outside traditional boundaries of security become security issues when they are recognized as an existential threat to a referent object.
