The concerns of national and international security have evolved considerably since the days of the Cold War. While states are still concerned with traditional threats such as military aggression from other states, emerging issues present different, yet no less compelling, challenges to security. These new challenges include terrorism and the proliferation of weapons of mass destruction, failed states, environmental catastrophes and major public health crises such as HIV/AIDS. This course explores how security policy issues are addressed at the national and international level. How prepared are agencies and organizations to meet newer security challenges? Are classic doctrines of deterrence still applicable? To what extent can technology be relied upon, as a tool to address current security needs?
