Interview Frieden und Sicherheit | Peace and Security Think Piece No. 1: Is there a need for new peace and security rules in the twenty-first century 01.09.2015 Herbert Wulf, Mely Caballero-Anthony and Marius Müller-Hennig Is there a need for new peace and security rules in the twenty-first century? Wulf, Herbert ; Caballero-Anthony, Mely ; Müller-Hennig, Marius Zur Publikation This Think Piece provides the basis for the subsequent work of the Reflection Group. The authors explain why it is necessary to discuss the state monopoly on the use of force, which they assume to be a central pillar of the security order. They identify major trends, changes and challenges in the area of peace and security policies, and conclude by developing main questions for the group. Summary Security policy is driven by current events and practical strategies to deal with urgent challenges need to be devised fast. These policies are mostly short-term and ad hoc ones. Yet, they often have serious longterm consequences for security orders. The perfect model of a state exercising a legitimate monopoly on the use of force over a given territory has probably never been fully implemented. Nevertheless, a large number of fragile and less-developed states worldwide aspire to functioning monopolies on the use of force. Major changes in the arena of peace and security policy and new challenges like the broadening of security concepts or the privatization and commercialization of force have further complicated security provision, too. The reflection group shall focus on concept and practice of the monopoly on the use of force as a central pillar of security order. It shall look beyond day-to-day policy and provide orientation for the longer term developments of security provision for the 21st century.
