Explanation:

President Harry Truman had terrible dilemmas when facing the invasion and future occupation of Japan.

According to some estimates made by U.S. planners and commanders, the invasion of the main Japanese islands would produce a very high number of American casualties , hundreds of thousands of soldiers, maybe even up to a million American lives would be lost. A horrendous perspective by itself, there was a question of whether the American public would tolerate such terrible figures; war in Europe had ended and people wanted their boys back in home as soon as possible.

Besides, fierce, stubborn resistance of the Japanese military and people was expected.

So, according to American historians, Truman opted to drop the atomic bomb to inflict such terrible damage and life loss on Japan so that the empire would surrender and hundreds of thousands of American lives would be saved. After Hiroshima and Nagasaki, Japan formally surrendered on September 2, 1945.
