As a primary source for reliable information on nuclear weapons, the Project is a frequent advisor to governments, parliamentarians, the news media, institutes, and non-governmental organizations. </p> <p>The Nuclear Information Project is directed by <a href="https://fas.org/expert/hans-kristensen/" target="_blank" rel="noreferrer noopener">Hans M.
