Currently, I am working on a thesis about Sweden-NATO partnership. My main question is what factors influence the perception of various political forces in the country towards NATO membership? Taking into consideration the fact that the country does not want to change its previous institutional decision, to my mind, Sweden should become a member if it can change its policy, because nowadays is under a threat. Furthermore, I am thinking of using path dependence theory as a reflector of the institutional traditions of this country. For this I need new materials, the speeches of government officials or the proof of changes in Sweden's foreign policy, as well as NATO perception.
