Final answer:
President Eisenhower continued Truman's policies by retaining and expanding parts of the New Deal like Social Security, managing high defense spending, and balancing the budget, while also cautioning against the military-industrial complex.
Step-by-step explanation:
President Dwight D. Eisenhower continued several of Truman's domestic policies when he assumed office in 1953. Despite his conservative fiscal approach, Eisenhower chose to keep and even expand parts of the New Deal, a set of programs initiated by Franklin D. Roosevelt and continued by Truman to provide relief, recovery, and reform during and after the Great Depression. Notably, Eisenhower expanded Social Security, exemplifying his moderate political stance and his aim to balance the budget while building a strong system of national defense. He managed high levels of defense spending, reflecting his commitment to a strong national defense and prevention of communist expansion, similar to Truman's policy of containment. However, Eisenhower also warned against the growth of the military-industrial complex in his farewell speech, highlighting potential risks associated with high defense spending.
