Korean War in 1950 (NSC)

Interagency Process

Regardless of the scale of the problem, a successful foreign policy–making process starts by defining interests and goals. Policymakers and their advisors then formulate policy options to meet those goals and consider each option’s strengths and weaknesses. This process is challenging. In the best of times information can be unreliable or incomplete or an adversary’s intentions can be unclear. Often a decision’s consequences can be unknowable. Leaders frequently have to choose from a list on which every option is imperfect. Adding to this uncertainty is the complexity of the U.S. government’s foreign policy machinery. Numerous agencies—each with its own interests and biases—seek to influence how policy is decided and carried out. It takes considerable effort to run a process capable of producing sound policy decisions.

The National Security Council (NSC) plays a critical role in this effort. Its mission is to help the president effectively use a variety of instruments—military, diplomatic, or otherwise—to forge policies that advance U.S. national security goals.

The NSC was created by the National Security Act of 1947. This act defined the NSC as an interagency body intended to “advise the president with respect to the integration of domestic, foreign, and military policies relating to the national security.” The period after World War II was an age of expanded American interests and responsibilities. The NSC was expected to provide a place where the heads of federal departments and agencies could cooperate to develop recommendations for policies that would advance U.S. aims. The NSC and its staff were also meant to manage the policymaking process. This ensured that the president would receive a full range of advice and opinion from the departments and agencies involved in national security.

The NSC has evolved significantly over the years. The NSC has adapted to the preferences of successive presidents and the challenges they faced. Variables such as the attendees, the frequency of meetings, the manner in which information is passed to the president, the importance of consensus, and the relative dominance of the NSC over other government institutions have changed over the decades.

The NSC has evolved to comprise various interagency committees and a large staff to prepare analysis and coordinate policymaking and implementation. The NSC is at the center of the interagency process. This process is one through which relevant government agencies address foreign policy issues and help the president make and execute policy choices.

I. National Security Advisor

The national security advisor (formally assistant to the president for national security affairs) is at the heart of the NSC structure. The national security advisor’s role is twofold: to offer advice to the president and to coordinate and manage policymaking. Because they have direct access to the president and do not represent a cabinet department, national security advisors are in a unique position. From this neutral perch they drive foreign policy decisions, manage the actors involved, and mitigate conflict throughout the decision-making process.

II. National Security Council Staff

The NSC staff consists of individuals from a collection of agencies that support the president, the vice president, and the administration. NSC staff members are generally organized into directorates that focus on regions or issues. The size and organization of the staff vary with each administration.

The NSC staff provides expertise for the variety of national security policy matters under consideration. It manages numerous responsibilities, including preparing speeches, memos, and discussion papers and handling inquiries from Congress on foreign policy issues. Staff members analyze both immediate and long-standing issues and help prioritize  the agenda.

III. Committee Structure

Committees are at the core of policy deliberation and policymaking in the NSC. They fall into four categories:

  • The highest level is the National Security Council itself. Formal NSC meetings are chaired by the president and include individuals named by the National Security Act of 1947 as well as other senior aides the president invites.
  • The Principals Committee (PC) comprises cabinet-level officials who head major government departments concerned with national security, such as the secretaries of state and defense. The national security advisor traditionally chairs the Principals Committee.
  • The Deputies Committee (DC) includes the deputy leaders of the government departments represented on the principals committee and is chaired by the deputy national security advisor.
  • Interagency Policy Committees (IPCs) cover a range of regional areas and issues. Each committee includes officials who specialize in the relevant area or issue at one of the departments or agencies in the interagency system. IPCs are generally chaired by senior directors on the NSC staff. Much of the day-to-day work needed to formulate and implement foreign policy across the U.S. government happens at the IPC level.

This committee structure tackles both immediate crises such as an outbreak of conflict and enduring issues such as climate change. IPCs conduct analysis on an issue, gather views on it and its importance from various departments, formulate and evaluate policy options, and determine what resources and steps would be required to carry out those options. The Deputies Committee manages the interagency process up and down. It decides what IPCs to establish. and gives them specific assignments. It also considers information submitted by the IPCs before relaying it to the Principals Committee or the full NSC.

The Principals Committee is the highest-level setting, aside from the NSC itself, for debating national security issues. It consists of the heads of the NSC’s component agencies. The Principals Committee is essentially all the members of the NSC except the president and vice president. Formal NSC meetings, which the president chairs, occur whenever the president sees fit. They consider issues that require the president’s personal attention and a direct presidential decision.

The goal of this committee structure is to foster consensus on policy options or highlight where and why consensus cannot be reached. If officials at one level agree on an issue, it does not need to go to senior officials for a decision. This practice reserves the president’s time and that of members of the Principals Committee for the most complicated and sensitive debates.

When a crisis erupts issues sometimes do not follow the usual path up from the IPCs. In these cases, NSC staff members and officials in government departments and agencies generally draft papers drawing on their expertise, available intelligence, and any existing contingency plans. Policy options are then debated and decided at the appropriate level. The policymaking process can also deviate from this model based on the preferences of each president.

For the purposes of this NSC simulation, you will role-play the NSC meeting with the assumption that the committees described have already done their jobs. Any critical information has already been passed to the highest-level decision-makers.

Presidential Decisions

When the president makes a policy decision, it can take the form of a verbal instruction recorded and shared with relevant departments and agencies. The president can also issue formal decisions in documents that lay out the administration’s policy and explain its rationale and goals. These documents have gone by different names under different presidents. President Joe Biden issues national security memoranda and national security study memoranda. President Donald Trump issued national security presidential memoranda.

The president can also issue an executive order (EO). EOs are a more formal and public declaration of policy. In contrast, national security directives are generally directed internally to federal departments and are often classified. In the past, presidents have issued EOs for such purposes as facilitating sanctions against foreign individuals and establishing new offices in government departments to carry out foreign policy aims. For federal agencies, both national security directives and executive orders carry the full force of law.
