A 1939 stockpiling act required the Secretary of War, the Secretary of the Navy, and the Secretary of the Interior, to determine whether certain materials purchased under the Act were strategic and critical. Once this determination was made, they then were permitted to determine the quality and quantities of materials to be purchased under the Act.[694] The Secretary of War and the Secretary of the Navy, when they considered such action appropriate because the domestic production or supply of certain materials was insufficient to meet the industrial, military, and naval needs of the country, were to direct the Secretary of the Treasury, through the medium of the Procurement Division of his Department to make purchases in accordance with specifications prepared by the Procurement Division of the Treasury Department and approved by the Secretary of War and the Secretary of the Navy. Two months later Congress authorized the Commodity Credit Corporation to accept such strategic and critical materials in exchange for such surplus agricultural commodities; and for the purpose of such exchange it was left to the three Secretaries to determine which materials are strategic and critical and the quantity and quality of such materials needed.[695] The Central Intelligence Agency Act of 1949 set up procedures for granting asylum to foreign nationals who have performed valuable security services for the United States. Whenever the Director of the CIA, the Attorney General, and the Commissioner of Immigration determines that the entry of a particular alien for permanent residence is in the interest of national security or essential to the furtherance of the national intelligence mission, such alien and his immediate family shall be given entry into the United States for permanent residence without regard to their inadmissibility under the immigration or any other laws and regulations, or to the failure to comply with such laws and regulations pertaining to admissibility.[696] The Immigration and Nationality Act of 1952 assigns to the Secretary of State, the Secretary of Commerce, and the Attorney General jointly the function of determining the annual quota of immigrants for any quota area.[697] On June 30, 1952, the President issued a proclamation reciting that the quotas had been determined, and listing them.[698] The National Security Act of 1947 recited as one of its purposes the establishment of integrated policies and procedures for the departments, agencies, and functions of the Government relating to the national security.[699] CO-OPERATION Joint decision-making shades into co-operative relationships which, if loose and flexible, may be continuing and steady. Such relations may exist with private as well as official groups.
