The securitization theory, on the other hand, argues that threats are discursively constructed and “securitization like politicization, has to be understood as essentially an intersubjective process” 
According to the securitization theory, when the process of securitization is successfully accomplished, this allows the political elite to take “emergency measures and (justifies) actions outside the normal bounds of political procedure”.
“The use of this speech act had the effect of raising a specific challenge to a principled level, thereby implying that all necessary means would be used to block that challenge” (Wæver, 2011:95). Securitization legitimizes the use of force and allows the state to mobilize or to take special powers to handle existential threats.
