The responsibility of the state in transnational armed conflicts using armed unmanned aerial vehicles

In this thesis, a state's responsibility for operations outside its own country using Armed Unmanned Aerial Vehicles during transnational armed conflicts is examined. In this context, firstly, the emergence of Armed Unmanned Aerial Vehicles, the factors that caused them to be included in the literature, and the place of these vehicles within the study's scope was expressed. The study's primary focus is the use of Armed Unmanned Aerial Vehicles within the scope of the new type of armed conflict that is conceptualized as "transnational armed conflict" and found in international law, and the legal problems arising from this use by states. These problems are examined in the study around the concept of "responsibility" as a branch of international law. Therefore, the study, which is predominantly normative, what the subject means in terms of "responsibility" in international law, the bases of the responsibility, the circumstances revealing the responsibility, the circumstances precluding the responsibility, and the reparation are explained. On the other hand, in the phenomenal aspect, the Armed Unmanned Aerial Vehicle operations carried out by the USA in Afghanistan, Pakistan, and Yemen between 2001 and 2019 were discussed as case studies. The results of the case studies in these countries in terms of "responsibility" have been analyzed. Thus, it was attempted to determine how the normative regulations correspond to concrete events. The findings were presented as conclusions of the thesis in the last part of the study.
