If the President determines that the furnishing of assistance to any nation— (a) is no longer consistent with the national interest or security of the United States or the policies and purpose of this Act; or (b) would contravene a decision of the Security Council of the United Nations; or (c) would be inconsistent with the principle that members of the United Nations should refrain from giving assistance to any nation against which the Security Council or the General Assembly has recommended measures in case of a threat to, or breach of, the peace, or act of aggression, he shall terminate all or part of any assistance furnished pursuant to this Act. The function conferred herein shall be in addition to all other functions heretofore conferred with respect to the termination of military, economic, or technical assistance.
