Felix Morley

The advocate of an aggressive foreign policy is therefore likely to be an advocate of centralization. For he cannot consistently urge that the Administration be untrammeled in its conduct of foreign relations yet subject to strict Constitutional checks and balances in its control over domestic activities. Conversely, the advocate of a limited foreign policy cannot consistently urge that the Executive should be given power to override local government in social issues, such a FEPC or Federal control of education. One may support either the expansion or the limitation of Presidential power. To advocate both simultaneously is perilously close to double talk.
