Active in the Democratic Party, Truman was elected a judge of the Jackson County Court (an administrative position) in 1922. He became a Senator in 1934. During World War II he headed the Senate war investigating committee, checking into waste and corruption and saving perhaps as much as 15 billion dollars.
As President, Truman made some of the most crucial decisions in history. Soon after V-E Day, the war against Japan had reached its final stage. An urgent plea to Japan to surrender was rejected. Truman, after consultations with his advisers, ordered atomic bombs dropped on cities devoted to war work. Two were Hiroshima and Nagasaki. Japanese surrender quickly followed.
In June 1945 Truman witnessed the signing of the charter of the United Nations, hopefully established to preserve peace.
