To the time of the writing of Taft's book, A Foreign Policy for Americans, his views on the problem of American security could be characterized as follows: (1) The paramount purpose of American policy is to preserve individual liberty in the United States. (2) Foreign aid programs, defense preparations, and above all war itself jeopardize liberty because of the regimentation and taxation they require. (3) Security measures should therefore be selected in terms of two potentially contradictory considerations: they must be adequate to prevent or win war, but they must not be so extensive as to undermine from within the liberty which they are designed to preserve. Until the writing of the book Taft sought to resolve this dilemma by minimizing foreign threats and consequently by minimizing the need for domestic activities which he thought would endanger liberty. Where he recognized the need for such activities, he was inclined to restrict expenditures, to select military means, and to delimit the geographic zone of defense so as to keep domestic danger to liberty at a minimum. His emphasis was more on domestic dangers than on foreign dangers. (4) Although favoring containment of the Soviet Union and Communism, and supporting the principle that a Soviet attack on western Europe would mean war with the United States, Taft preferred not to have formal European allies and not to rearm them collectively; above all, he opposed any advance commitments to engage in land warfare. Belief that the security of western Europe was vital to the security of the United States had, at least, not become an ingrained part of his thought. (5) He professed to adhere to the principle of collective security, but in practice he twice abandoned it—in relation to the Axis and in relation to Korea. After Korea, Taft looked upon the UN with disfavor. (6) Taft regularly insisted upon preserving Congressional prerogatives in the field of foreign affairs. He put serious reservations on bipartisanship, and he distrusted the Department of State.
Several significant, though subtle, changes in Taft's position are evident in his book. Nowhere are previous positions explicitly repudiated, yet there are modifications, omissions, and shifts of emphasis. The preservation of individual liberty in the United States is still the primary objective, but Taft has shifted somewhat away from preoccupation with domestic dangers to American liberty toward greater concern for foreign dangers. He no longer minimizes the Soviet Union as a military threat.
