1945年6月16日,杜鲁门会见了陆军部长和联席会议主席,他们共同商讨了打败日本的策略,核心策略是继续进行大规模的常规轰炸,或者登陆日本诸岛。投掷原子弹和外交斡旋都尚未纳入考虑范围。但是,史汀生和副部长仍坚持日本只有无条件投降,美国才会考虑保留其天皇;如果日本否定此建议,那么,美国将会考虑使用原子弹。 On June 16, 1945, Truman met with Army Ministers and the chairmen of the Joint Conference. They discussed the strategy of defeating Japan. The core strategy was to continue the massive conventional bombing or landing on the Japanese islands. Throwing atomic bombs and diplomatic mediation have not yet taken into account. However, Stimson and his deputy also insisted that Japan would consider retaining the emperor only if it unconditionally surrendered. If Japan denies this suggestion, the United States will consider using the atomic bomb.
