In an April 2009 speech in Prague, President Obama said that nuclear terrorism is the “most immediate and extreme threat to global security,” and announced “a new international effort to secure all vulnerable nuclear material around the world within four years.” To mobilize world leaders to meet this goal, the President hosted a Nuclear Security Summit in Washington, DC, on April 12-13, 2010. Heads of State from 47 countries gathered to lay out their priorities and focus the world’s attention on the issue.
