Secretary of State, Marshall also urged Truman to immediately call for The Netherlands to stop their invasion of Indonesia, a former Dutch colony which had declared independence in 1945. The Netherlands ignored the Truman administration's initial entreaties. As a result, the Marshall Plan program for the Netherlands' economic recovery was put on hold and the Truman administration threatened to cut all economic aid. The Netherlands finally agreed to withdraw and transferred sovereignty following the Dutch–Indonesian Round Table Conference in 1949. Marshall resigned as Secretary of State because of ill health on January 7, 1949. He was severely exhausted throughout his tenure in the position. Dean Acheson in late 1947 said he was underperforming like "a four-engine bomber going only on one engine." Truman named him to the largely honorific positions of chairman of the American Battle Monuments Commission and president of the American National Red Cross. He received the 1953 Nobel Peace Prize for his post-war work, despite the criticism that he was a warrior not a pacifist. Secretary of Defense When the early months of the Korean War showed how poorly prepared the Defense Department was, President Truman fired Secretary Louis A. Johnson and named Marshall as Secretary of Defense in September 1950. The appointment required a congressional waiver because the National Security Act of 1947 prohibited a uniformed military officer from serving in the post. This prohibition included Marshall since individuals promoted to General of the Army are not technically retired, but remain officially on active duty. Marshall was the first person to be granted such a waiver; in 2017, Jim Mattis became the second and in January 2021, General Lloyd Austin became the third. Marshall's main role as Secretary of Defense was to restore confidence and morale to the Defense Department while rebuilding the United States Armed Forces following their post-World War II demobilization. Korean War Marshall worked to provide more manpower to meet the demands of both the Korean War and the Cold War in Europe. To implement his priorities Marshall brought in a new leadership team, including Robert A. Lovett as his deputy and Anna M. Rosenberg, former head of the War Manpower Commission, as assistant secretary of defense for manpower. He also worked to rebuild the relationship between the Defense and State Departments, as well as the relationship between the Secretary of Defense and the Joint Chiefs of Staff.
