Answer:
b. It demonstrated Japan's military resilience, influencing the decision.
Step-by-step explanation:
The Battle of Okinawa, fought from April to June 1945, was a brutal and costly confrontation between the Allied forces, primarily the United States, and the Japanese Empire. The intense resistance encountered by the Allies during this battle, along with the high casualties on both sides, gave President Truman a glimpse of the fierce Japanese defense.
This demonstration of Japan's military resilience played a role in Truman's decision to use the atomic bomb. The battle highlighted the potential difficulties and heavy losses that could be involved in a full-scale invasion of the Japanese mainland. The belief that Japan would fiercely resist any invasion and that the cost in terms of lives lost would be extremely high contributed to Truman's decision to use the atomic bomb as a means to bring a quicker end to the war. The bombings of Hiroshima and Nagasaki followed shortly after the Battle of Okinawa in August 1945.
