National Security Decision Directive 77 (NSDD-77; titled Management of Public Diplomacy Relative to National Security), was a U.S. National Security Directive signed on January 14, 1983 by President Ronald Reagan. The directive established a Special Planning Group (SPG) under the National Security Council (NSC) whose purpose was to strengthen, organize, plan, and coordinate public diplomacy of the United States relative to national security. This NSDD positioned the White House and the National Security Staff at the helm of public diplomacy coordination across government agencies. NSDD-77 lay the groundwork for the Reagan administration's aggressive public diplomacy strategy and included guidance for inter-agency working groups to execute wide ranging tactics for information dissemination
