The thesis examines the phenomenon of state collapse and its normative and policy implications for the international system and international security. It contemplates the impact of state collapse on the concepts of government, statehood and sovereignty as well as on the role of non-state actors in internal conflicts and analyses the implications of implosion of government on the architecture and functioning of the international system. A major conclusion is that the phenomenon of state collapse reveals the need for greater development of the rules, procedures and institutions of the international political and legal system towards the creation of a more sophisticated international system, which can balance effectively the demands for a more centralised and supranational structure with the requirements for a more flexible and transnational functioning of the international system
