Answer:
You did not include the choices however one of them was to demonstrate the power of the atomic bomb to the Japanese by dropping it on an unpopulated area and I would have done that.
Choice: Demonstrate power of bomb by dropping it on Unpopulated Area
Positive : Over a 100,000 Japanese civilians would have been spared death and property would not have been destroyed on a massive scale. Also the area would not be radioactive leading to adverse effects on generations of people born near the drop zone.
Negative: The Japanese were very defiant and stubborn in their fighting and so might have ignored the demonstration which would have meant that we wasted 50% of our nuclear bombs as the United States because only 2 existed in the world at the time and the U.S. had both.
