This chapter focuses on the concept of diffusing insecurities to create an opening towards studying similar securitising practices that unbind security and that work limits of democratic practice through associative dispersing of insecurities in non-intensifying modes. It presents changes in North Atlantic Treaty Organization (NATO's) strategic concept to look at how scattering of insecurities took place in the period after the end of the Cold War. The chapter introduces that the combination of a move from defining existential threats to risk and uncertainty and a related blurring of divisions of security labour are central to diffusing insecurities. It considers the diffusing insecurities challenges limits of security by turning limits into more ambivalent and porous boundaries and by creating insecurity continuities. The chapter shows how the mere circulation of insecurities securitises without enacting the intensifying rationale of the national security tradition; practices, statements, subjects and things are security associated rather than aggregated into an existential threat.
