The Proliferation Security Initiative

This Air University research paper is an examination of the Proliferation Security Initiative. Through extensive research and review of academic journals, governmental sources, and press reporting, combined with interviews of relevant personnel in the Departments of Defense and State, the Proliferation Security Initiative is chronicled from its inception in early 2002 through the latest multinational exercises. Special attention is given to the guidelines governing participation in PSI and the key issues -- legal authorities and intelligence sharing -- relevant to PSI operations.
