"The emergence of the national security problem, that is, the inescapable and inseparable amalgam of foreign policy and military policy, as the leading problem (and you have only to look in the newspaper this morning, or any morning, to realize that it is the problem) was signalized by the passage of the National Security Act of 1947...A final word should, however, be added with reference to the role of NSC in organizing our national security. Important as it is in the formulation of Americas grand strategy, neither it nor the legislation that created it has diminished the constitutional authority of the President of the United States. He retains the major role and also the major responsibility on his shoulders for our national security...Nor has the authority of the Congress been decreased. Congress maintains the highly important task of cooperating in the establishment of national security policy, in providing for organizations and agencies (it has to create them by statute) and in keeping the American public informed both as to our needs and as to the progress we are making in attaining adequate national defense."
