The aim of the research is to explain and assess the change in the direction of KFOR operations in relation to the evolution of threats to Kosovo’s security. The research problem is contained in the form of the following question: how has the KFOR operation profile changed in relation to the evolution of the security situation in Kosovo? In the course of the research carried out, it was found that the North Atlantic Treaty Organization in the considered time perspective performed tasks related to peace enforcement, stabilising the security situation and creating the conditions for Kosovo to provide security on its own in the future. NATO is the leading international actor, responsible for organising and executing a wide range of activities to shape Kosovo’s security over last two decades. It is assessed that the dynamics of evolving threats to Kosovo’s security have become a vector for broad changes in the organisational structure of the KFOR mission, leading to a shift in the focus of force operations towards non-kinetic campaign. The emergence of non-military threats in the Kosovo’s security space after the ethnic conflict forced a change in the profile of KFOR operations, both in organisational and functional terms. The need to undertake operations of a stabilising nature caused a change in the NATO’s approach to the conduct of military operations in Kosovo, which became a vector for subsequent Allied operations of a peacekeeping and stabilising nature. The research methods used in the study are: critical analysis and evaluation of the literature, participant observation, systems analysis, deduction and synthesis.
