Quizplus · Accepted Answer

The key to President Eisenhower's New Look in foreign policy was to have a smaller conventional army bolstered by strength in airpower and nuclear weapons. This was in contrast to Truman's policy of containment, which relied more heavily on conventional ground forces. Eisenhower believed that airpower and nuclear weapons could serve as a deterrent against aggression and reduce the need for large-scale conventional warfare.
