Which body coordinates foreign policy and defense policy under the chairmanship of the President?

The National Security Council is the body that coordinates foreign policy and defense policy under the chairmanship of the President. This council serves as the principal forum used by the President for consideration of national security and foreign policy matters. It includes the President, the Vice President, Secretaries of State and Defense, and other key officials, who advise and assist the President in decision-making related to national security and foreign affairs.

The role of the National Security Council (NSC) is essential as it ensures that the various sectors of the U.S. government—such as defense, intelligence, and public diplomacy—are aligned in their approaches to issues that affect the nation's security and foreign relationships. This coordinated effort is vital for effective policy-making and implementation in an increasingly complex global environment.

The other entities mentioned, like the Department of State, primarily focus on diplomatic activities and foreign relations, while the Congressional Defense Committee is involved in legislative oversight and budgetary matters related to defense, rather than direct policy coordination under the President's leadership. The Joint Chiefs of Staff, on the other hand, provide military advice and support to the President and may execute military policy, but they do not coordinate overall foreign policy or defense policy as the NSC does.
