This course explores the nature and problems of achieving human security in the 21st century. Reflecting changes in the world and in the field of national security studies, the course includes both the horizontal and vertical expansion of security.  The field has expanded horizontally to include both military and non-military threats to not only physical well-being, but also economic, cultural, and social welfare. With regard to the vertical expansion of security, the course covers not only the traditional concerns of national security (e.g., creation and use of military force for physical security of the territorial-state), but also the definition and achievement of individual and global security in the face of non-military problems.  The course seeks to increase understanding of the nature of security, review a series of problems, analyze the individual, state, and global policy options.  While security policy cannot be made without value choices, no particular set of values is advocated.
