The National Security Strategy (NSS) is a document prepared periodically by the executive branch of the government of the United States for Congress which outlines the major national security concerns of the United States and how the administration plans to deal with them. The legal foundation for the document is spelled out in the Goldwater-Nichols Act. The document is purposely general in content (contrast with the National Military Strategy, NMS) and its implementation relies on elaborating guidance provided in supporting documents (including the NMS).
The stated intent of the Goldwater-Nichols legislation is broadly accepted as valid for effective political discourse on issues affecting the nation's security--the Congress and the Executive need a common understanding of the strategic environment and the administration's intent as a starting point for future dialogue. That said, however, it is understood that in the adversarial environment that prevails, this report can only provide a beginning point for the dialogue necessary to reach such a "common" understanding.
The requirement of producing this report along with the budget request leads to an iterative, interagency process involving high level meetings that helps to resolve internal differences in foreign policy agendas. However, “this report was not to be a neutral planning document, as many academics and even some in uniform think it to be. Rather it was … intended to serve five primary purposes.”
Where the incoming executive team has not formulated a national security strategy, such as an after an election in which foreign policy and defense were not important campaign issues, the process of writing the report can be of immense importance:
Few things educate new political appointees faster as to their own strategic sensings, or to the qualities and competencies of the "permanent" government they lead within executive bureaucracies, than to have to commit in writing to the President their plans for the future and how they can be integrated, coordinated and otherwise shared with other agencies and departments. The ability to forge consensus among these competing views on direction, priorities and pace, and getting "on board" important players three political levels down from the president is recognized as an invaluable, if not totally daunting, opportunity for a new administration.
In order to defeat al Qaeda and the Taliban in Afghanistan, according to the National Security Strategy of 2010, the United States needs to engage in a large amount of interagency cooperation and communication with the Muslim population in Afghanistan and throughout the world. The objective of the National Security Strategy is to create a stable situation for the world, including those countries struggling with insurgencies. “The most effective long-term measure for conflict and resolution is the promotion of democracy and economic development." In order to promote democracy and economic development communication with the civilian population of the host-nation is essential. The Stability Operations Field Manual states that success depends on a U.S. ability to build local institutions and in the establishment of a legitimate permanent government, which builds trust between the citizens and the counterinsurgency personnel." The National Security Strategy establishes the interagency coordination in order to conduct useful public diplomacy to secure the population in the countries of Afghanistan and Iraq.
