Answer: Dwight D. Eisenhower brought a "New Look" to U.S. national security policy in 1953. The main elements of the New Look were: (1) maintaining the vitality of the U.S. economy while still building sufficient strength to prosecute the Cold War; (2) relying on nuclear weapons to deter Communist aggression or, if necessary, to fight a war; (3) using the Central Intelligence Agency (CIA) to carry out secret or covert actions against governments or leaders "directly or indirectly responsive to Soviet control"; and (4) strengthening allies and winning the friendship of nonaligned governments. Eisenhower's defense policies, which aimed at providing "more bang for the buck," cut spending on conventional forces while increasing the budget for the Air Force and for nuclear weapons. Even though national security spending remained high—it never fell below 50 percent of the budget during Eisenhower's presidency—Eisenhower did balance three of the eight federal budgets while he was in the White House.
