ABSTRACT
This chapter explores the relationship between diplomacy and security through three perspectives: the international system level, national approaches and diplomatic aspects of security affecting the individual. The interpretation of the formal power of the UN Security Council has continued to evolve since 1945. Whilst its position as envisaged in article 24 of the UN Charter, through which the members conferred on the Council primary responsibility for the maintenance of international peace and security, has been eroded and challenged, its operations nevertheless remain an important feature of international order. The mandates underpinning UN operations in the maintenance of international peace and security are central to the evolving role and effectiveness of the Security Council. UN peacekeeping and other forces, in most cases, have traditionally operated on principles of impartiality; lightly armed and with defensive rules of engagement; and with the consent of the host state.
