Almost three decades after the end of the Cold War and the bipolar order, many uncertainties still remain regarding the nature of the current international system and the extension of the resulting changes as driving forces capable of shaping the International Relations agenda. In this environment that has changed fundamentally over recent years we have confronted highly complex issues, amongst them: one of the most critical refugee crises in our recent history and the need of a concerted humanitarian response to ensure human security; the scramble over scarce resources; energy demands, climate change and natural disasters; the digital realm and the increasing risk of cyber-warfare; the rising of new actors claiming the status of power and the associated possibility of a new Thucydides's trap; the future of US-China relationship and so on.
Accordingly, in a context prone to multiple connections of varied order, where the destinies of not only the traditional Nation-States but also of non-state actors are intertwined in different ways, we are led to think about all of these aspects as variables capable of potentially posing threats to the international security environment, from the systemic level to the regional and domestic ones.
Thus, taking into consideration the premise that this set of impending sources of threats should be increasingly considered in the scope of defense and security policies, some epistemological questions arise and deserve attention: firstly, to what extent these issues impact military planning in a challenging security environment? Concomitantly, is there room to rethink the role of armed forces in such a context?
Aimed at bringing a contribution to the discussion, this brand-new special issue of the Brazilian Journal of Studies and Advanced Researches on the Third Sector (REPATS) invited distinguished scholars on security, defense and strategic studies, from all over the world, to reflect about “the role of Armed Forces in a changing security environment” from theoretical, conceptual and historical perspectives through comparative analyses, case studies and others qualitative and quantitative approaches.
