In this chapter I argue that securitization theory can be a useful entry-point in a variety of studies dealing with broader fields of human action. The question is what the study of securitization can bring to various debates on political theory or the study of persuasion, legitimization, and social mobilization for example. Here, I relate securitization theory with research on social mobilization and its suppression, and thereby argue that securitization theory has something to offer for this broader field of study.
