The Justification of Dropping the Atomic Bomb on Japan: A Historical Analysis

For many decades, the decision by the United States to drop atomic bombs on Hiroshima and Nagasaki has been a subject of intense debate. The conventional narrative suggests that the bombs were a necessary evil to end the war in the Pacific and save countless lives. However, historical evidence and analysis reveal a more complex picture that challenges this view.

Historical Context and Precedent

The United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively. This event marked the first and only use of nuclear weapons in war history. The justification for these bombings has been widely discussed, with arguments both in favor and against their use. Among those opposed to the decision, the most prominent points include:

Truman's Survey and Military Advice

President Harry S. Truman commissioned a survey in 1946 to investigate the effectiveness of dropping the atomic bombs. The report concluded:

Based on a detailed investigation of all the facts and supported by the testimony of the surviving Japanese leaders involved, it is the Survey’s opinion that 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, even if Russia had not entered the war, even if no invasion had been planned or contemplated.

Moreover, General Dwight D. Eisenhower, the then-Chief of Staff of the U.S. Army, also had reservations about the necessity of using the atomic bomb. He stated:

“First the Japanese were ready to surrender and it wasn’t necessary to hit them with that awful thing. Second I hated to see our country be the first to use such a weapon.”

Similarly, Admiral William Leahy, Truman's Chief Military Advisor, expressed his viewpoint:

“is my opinion that the use of this barbarous weapon at Hiroshima and Nagasaki was of no material assistance in our war against Japan….” “The Japanese were already defeated and ready to surrender because of the effective sea blockade and the successful bombing with conventional weapons.”

Japanese Surrender and Soviet Involvement

The National Museum of the U.S. Navy provides additional context, stating:

“The vast destruction wreaked by the bombings of Hiroshima and Nagasaki and the loss of 135,000 people made little impact on the Japanese military. However the Soviet invasion of Manchuria and Korea…changed their minds.”

According to this narrative, the Soviet invasion of Manchuria and Korea was a significant factor in Japan's decision to surrender, rather than the atomic bombs.

Conclusion: Multiple Choices and Their Consequences

In 1945, the United States faced three primary options:

While the third option undoubtedly had severe consequences, it is argued that it could have saved countless more lives compared to the alternative methods. President Truman, faced with moral and practical dilemmas, chose what he believed was the lesser of many evils.

Final Reflections

In conclusion, the decision to drop the atomic bombs on Hiroshima and Nagasaki remains a contentious issue. While the historical evidence suggests that the atomic bombs were not strictly necessary to achieve Japan's unconditional surrender, it is important to acknowledge the humanitarian cost of alternative options. The decision ultimately saved millions of lives and brought an end to the conflict, making it a critical but controversial moment in world history.
