Question

Which situation influenced Harry S. Truman's decision to use atomic weapons against Japan?

Strong resistance by the Japanese showed that an invasion of Japan would result in a large number
of U.S. casualties.
Many U.S. navy ships were destroyed during battles in the Pacific, and the Allies were not ready to
send reinforcements.
The U.S. military needed to move supplies from the Pacific to help with fighting in Europe.
The U.S. military's island-hopping campaign against Japan was unsuccessful, and U.S. public
opinion was turning against the war.

Answer 1

Answer:Tha U.S public opinion was turning against war

Step-by-step explanation:

Second factor in Truman’s decision was the legacy of Roosevelt, who had defined the nation’s goal in ending the war as the enemy’s “unconditional surrender,” a term coined to reassure the Soviet Union that the Western allies would fight to the end against Germany. It was also an expression of the American temperament; the United States was accustomed to winning wars and dictating the peace. On May 8, 1945, Germany surrendered unconditionally to great rejoicing in the Allied countries. The hostility of the American public toward Japan was even more intense and demanded an unambiguous total victory in the Pacific. Truman was acutely aware that the country—in its fourth year of total war—also wanted victory as quickly as possible.
