Execution is the application of plans and resources to achieve policy goals. Execution spans a wide range of activity in support of national security. Examples include: communicating U.S. policy to a foreign government; freezing assets of an organization supporting terrorism; delivering AIDS education to an African village; negotiating a free trade agreement with a foreign government; interdicting WMD shipments in the Persian Gulf; or searching for terrorists in the Afghanistan countryside.
All departments and agencies execute policy both in Washington and in the field. The President or cabinet officials can also play an execution role, particularly during crisis situations by communicating U.S. policy to and negotiating with foreign leaders.
