Abstract
This essay is based on Mark Duffield's article (2007): Development, Security and Unending War. This article provides us with an analysis of three different books. What is interesting is to understand in what way these articles share the same focus even if, at first, they seem really opposed. They present specific elements that help us to distinguish the changes in the problematic security from the centered security on the inter-state threat of war to the insecurity coming from a permanent potential instability. Mary Kaldor focuses more precisely on the fact that the questions of international security and development have become internationalized following the globalization process. Her main concept is the idea of human security: the problems of security should not be studied only at the state level but also at the level of individuals.
