Internal reorganization was only one of several major changes during Wilson's tenure, the most important being the "New Look" defense concept. Eisenhower had criticized Truman's policies during the 1952 campaign, arguing that they were reactive rather than positive and that they forced the United States to compete with the Soviet Union on the latter's terms. Eisenhower entered office with strong convictions about the need to reorient the nation's security policy by maintaining a staunch defense while decreasing government expenditures and balancing the budget.
