The Obama Administration has launched two new series of Presidential directives on national security policy. Presidential Policy Directives (PPDs) will define and direct the implementation of new presidential policies. Presidential Study Directives (PSDs) will initiate policy review and development procedures.
Presidential Study Directive-1 (pdf), issued February 23, 2009, is entitled “Organizing for Homeland Security and Counterterrorism.”
The new PPD and PSD documents will succeed and replace directives known as National Security Presidential Directives (NSPDs) in the previous Administration.
