Step-by-step explanation:
One plausible reason why the United States decided to drop a second atomic bomb on Nagasaki was to demoralize the Japanese people ahead of a full invasion. The first atomic bomb dropped on Hiroshima had not immediately led to the surrender of Japan, so the second bomb was deployed to further show the devastating power of these weapons and accelerate the end of the war. The intention was to demonstrate the destructive capabilities of the atomic bombs and convince the Japanese government to surrender to avoid further casualties and destruction.
