Congress, in recommending passage of the bill, declared that "truth can be a powerful weapon." Congress further declared six principles were required for the legislation to be successful in action: tell the truth; explain the motives of the United States; bolster morale and extend hope; give a true and convincing picture of American life, methods, and ideals; combat misrepresentation and distortion; and aggressively interpret and support American foreign policy. As a Cold War measure, it was intended to compete with propaganda from the Soviet Union and Communist organizations primarily in Europe. The principal purpose of the legislation was to engage in a global struggle for minds and wills, a phrase used by Presidents Harry S. Truman and Dwight D. Eisenhower.
