From the Document: "On June 24, 2015, President Barack Obama issued Executive Order (EO) 13698, 'Hostage Recovery Activities', and Presidential Policy Directive (PPD) 30, 'U.S. Nationals Taken Hostage Abroad and Personnel Recovery Efforts'. The President also announced the release of an interagency 'Report on U.S. Hostage Policy', which reviewed U.S. responses to overseas hostage-takings and identified two dozen key findings and recommendations. Some security observers see these documents as reflecting a shift in the nation's hostage policy."
