This publication emphasizes the need for a United Nations Emergency Peace Service (UNEPS) and analyzes its key roles and requirements. UNEPS aims to create a permanent and standing, robust, highly trained and well-equipped UN military formation under the command of the Security Council. The author underlines that the UNEPS would ensure a prompt, effective response to armed conflicts and genocide, protect civilians, help-rebuilding and ensure collective peace and security. Furthermore, it would renew confidence in the UN as an organization, especially in its capacity and commitment to fulfill assigned tasks. The author concludes with recommendations for the next concrete steps towards such a UNEPS.
