The National Security Council, created by the National Security Act of 1947, is the instrument through which the President obtains the collective advice of the appropriate officials of the executive branch concerning the integration of domestic, foreign, and military policies relating to the national security. An outline of the genesis of this new governmental agency will indicate in part its present rôle.

Even before World War II, a few far-sighted men were seeking for a means of correlating our foreign policy with our military and economic capabilities. During the war, as military operations began to have an increasing political and economic effect, the pressure for such a correlation increased. It became apparent that the conduct of the war involved more than a purely military campaign to defeat the enemy's armed forces. Questions arose of war aims, of occupational policies, of relations with governments-in-exile and former enemy states, of the postwar international situation with its implications for our security, and of complicated international machinery.
