第四任期不到三个月，总统富兰克林·罗斯福去世。 哈里·杜鲁门死后两个半小时，宣誓就任美国总统。 杜鲁门在第二次世界大战期间被推上总统职位。 尽管欧洲战争显然对盟国有利，并且已经接近尾声，但太平洋战争却毫不留情地继续进行。 杜鲁门没有时间过渡。 领导美国走向和平是他的责任。 在完成罗斯福的任期时，杜鲁门负责做出重大决定，通过在广岛和长崎投下原子弹来结束与日本的战争
Less than three months after the fourth term, President Franklin Roosevelt passed away. Two and a half hours after the death of Harry Truman, he was sworn in as the President of the United States. Truman was pushed to the presidency during the Second World War. Although the European war is clearly beneficial to the allies and is nearing completion, the Pacific War has continued unrelentingly. Truman has no time to transition. It is his responsibility to lead the United States towards peace. Upon completion of Roosevelt’s tenure, Truman was responsible for making a major decision to end the war with Japan by casting atomic bombs in Hiroshima and Nagasaki.
