In recent years the political situation in the Baltic sea region has deteriorated. This can mainly be referred to a change in Russia’s threat posture, which has caused Sweden to refocus military strategic doctrine from international peace operations towards national defence. The new doctrine involves elements of deterrence through what is called a “threshold effect” which is aimed at discouraging a potential aggressor from taking military action towards Sweden. The doctrine is implemented despite obvious lack of military power and that recent research questions the usefulness of deterrence strategies. This essay examines to what extent the discourse in political security policy is implemented in development of new doctrine. This is done by examining two cases of doctrine development in conjunction with different discourses in Swedish security policy. The implementation of security policy is viewed as a framing process, where the security policy frame is projected at the Swedish armed forces through a defence bill. The result of the examination show that the discourse in political security policy have a high degree of resonance in the military doctrine but that there are some areas connected to the defence forces narrative and culture where the frame lacks resonance. The adaptation of a deterring threshold affect can be connected to these circumstances.
