After the Japanese fleet was destroyed at Leyte Gulf in October 1944, the U.S. was able to carry out uncontested bombing of Japan’s cities, including the hellish firebombings of Tokyo and Osaka. This is what Henry H. Arnold, Commanding General of the U.S. Army Air Forces, meant when he observed, “The Japanese position was hopeless even before the first atomic bomb fell because the Japanese had lost control of their own air.” Also, without a navy, the resource-poor Japanese had lost the ability to import the food, oil, and industrial supplies needed to carry on a World War....
As a result of the naked futility of their position, the Japanese had approached the Russians, seeking their help in brokering a peace to end the War. The U.S. had long before broken the Japanese codes and knew that these negotiations were under way, knew that the Japanese had for months been trying to find a way to surrender.
Fleet Admiral Chester W. Nimitz, Commander in Chief of the U.S. Pacific Fleet, reflected this reality when he wrote, “The Japanese had, in fact, already sued for peace.the atomic bomb played no decisive part, from a purely military point of view, in the defeat of Japan.” Admiral William D. Leahy, Chief of Staff to President Truman, said the same thing: “The use of [the atomic bombs] at Hiroshima and Nagasaki was of no material assistance in our war against Japan. The Japanese were already defeated and ready to surrender.”
Civilian authorities, especially Truman himself, would later try to revise history by claiming that the bombs were dropped to save the lives of one million American soldiers. But there is simply no factual basis for this in any record of the time. On the contrary, the U.S. Strategic Bombing Survey reported, “Certainly prior to 31 December 1945, and in all probability prior to 1 November 1945, Japan would have surrendered even if the atomic bombs had not been dropped.” The November 1 date is important because that was the date of the earliest possible planned U.S. invasion of the Japanese main islands.
To this day there are lasting after-effects of the A-bomb. Have we learned anything from this tragic use of force?
