“We knew the world would not be the same. A few people laughed, a few people cried, most people were silent. I remembered the line from the Hindu scripture the Bhagavad Gita. Vishnu is trying to persuade the prince that he should do his duty and to impress him takes on his multiarmed form and says, ‘Now, I am become Death, the destroyer of worlds.’ I suppose we all thought that one way or another.”1

Throughout the history of human warfare, conflict has pushed humans to innovate–to build ever larger and deadlier weapons, each more lethal than the last. However, it was not until World War II and the invention of the atomic bomb that humanity has been able to kill on such a massive and efficient scale. Case in point, in the final days of World War II, the United States carried out one of the most chilling instances of mass murder in the history of humanity: the bombing of the Japanese cities of Hiroshima and Nagasaki. These attacks ultimately killed an estimated 294,000 people, the majority of whom were noncombatants.2 In comparison, the Japanese attack on Pearl Harbor killed just 2,408 American citizens, although this is largely due to the focused Japanese attack on military targets, namely the Pacific fleet and U.S. airfields.3 To give a more modern frame of comparison, the terrorist attacks against the World Trade Center and Pentagon, considered to be by far the worst terrorist attacks against the United States, claimed the lives of 2,974 American citizens.4

In the spring of 1945, World War II was entering its final stages. The Allies had already achieved victory in Europe with Germany’s surrender on May 7th, but the conflict on the Pacific front was still going strong. In the years leading up to the two World Wars, Japan’s victories against two larger countries–China in the Sino-Japanese War (1894–1895) and Russia in the Russo-Japanese War (1904–1905)–combined with other factors, forged a strong sense of Japanese nationalism, militarism, and cultural superiority. This fervent nationalism, integrated with the Japanese warrior ethic known as bushido, made the prospect of a Japanese surrender unlikely, even as the Allies began to position for an invasion of the Japanese mainland.5

Concurrently, since as early as 1942, President Franklin Delano Roosevelt had been secretly sponsoring and funding The Manhattan Project, the code name used for the $2 billion U.S. effort to develop a nuclear weapon before the Germans. A team of top physicists led by Dr. Julius Robert Oppenheimer were assigned to this project, a task so secret that not even individuals as important as then Vice President Harry S. Truman was aware of it. Shortly after Roosevelt’s untimely death and Truman’s subsequent inauguration to the presidency in April 1945, he was informed that the Manhattan Project was approaching success–that a nuclear weapon would be feasible in just four short months.6

Faced with the prospect of a costly and deadly invasion of Japan, Truman and his advisors were faced with a difficult choice: utilize this new atomic weapon or try to defeat Japan through conventional means. In late July, the United States issued the Postdam Declaration, a statement which gave Japan the choice between unconditional surrender or total annihilation. When this declaration went ignored, President Truman authorized the use of the atomic bomb.7

On the morning of August 6, 1945, Colonel Paul Tibbets piloted the Enola Gay over the city of Hiroshima, where his crew dropped an atomic bomb code-named “Little Boy.” Upwards of 70,000 people died instantly in the blast. Additionally, 48,000 buildings were destroyed and another 22,000 were damaged, leaving only 6,000 buildings untouched. Three days later, on August 9th, a second bomb was dropped onto Nagasaki,  killing another 36,000 people. In total, an estimated 295,000 were killed in the blasts or from complications from the resulting nuclear fallout.8

Emperor Hirohito ordered the surrender of Japan on August 10, 1945. On August 15th, radios across Japan broadcasted Hirohito’s words as he read the declaration of surrender to the Japanese people, thus ending World War II. The bombs’ effectiveness in forcing the Japanese to surrender is still subject of popular debate among historians to this day, given that the Russian invasion of Japan-controlled Manchuria occurred at the same time of Nagasaki, both of which likely impacted Japan’s will to continue fighting.9 Even so, while the political and military effects of these blasts may be debated, none can contest their tragedy and devastation.

    I agree with this article when it says their is much debate about this first atomic bomb, politically. The U.S kept the Manhattan Project a secret in a race to beat the German Nazis with the same technology. With Russia being a threat and to avoid both a long war with Japan, and possibly a new war with the Russians, they dropped these bombs, not really knowing exactly what would come. All Project Manhattan’s members just knew, if the bombs did detonate that they would make history.

  • Antonio Holverstott

    The use of the atomic bomb has changed the way people have viewed warfare including fueling panic in the hearts and minds of men, women, and children during the Cold War between the USSR and their allies and the United States and its allies. I will say that the use of the atomic bomb on Nagasaki was ethical for two reasons. The first reason is that the US offered unconditional surrender to the Japanese prior to the bombing. The second reason is that prior to the bombing, US airmen dropped leaflets into these cities warning them of their bombing activities. However, I do not want to understate the effects the bombing had on the residents of the city in both mental and physical health.

  • Samuel Vega

    There was a race among the Germans, the Soviets, and the United States to build the atomic bomb. The Manhattan Project was so secretive that President Truman was not even aware of the effort until he became President. Knowing the power of the bomb, Truman he gave a declaration to Japan to say surrender or risk annihilation. The declaration was ignored by the Emperor. The effects of the bomb were devasting. Use of chemical or nuclear weapons may not be answer to solving a conflict. Knowing the impact of the bombing is one of the reasons we do not go into a nuclear conflict.

    I remember watching the documentaries on this topic. What I remember the most is the documentary showing the “shadows” portrayed on the walls of buildings. These were said to be the shadows of the people who were hit by the nuclear bomb and their bodies were what created the shadows left. I believe in warfare and I believe in threats, not to mention its honestly been in history for centuries, yet what the Americans did in a combat to pearl harbor was to detrimental. Even the scientist who made the bomb said themselves they made a mistake and regret what was done.

    This article does a good job in terms of displaying a timeline of events from the beginning of the end with the victory in Europe to the end of the war with victory in Japan. There is also great detail in this timeline that better portrays how events unfolded in regards to the development of nuclear weapons and how it forced leaders in Japan to consider surrendering. It was also good to incorporate the number of lives lost after the bombings compared to many terrorist attacks on the United States including 9/11. I feel it would have been a nice touch to hint at the start of the Cold War at the end of the piece to show the impact that the development of nuclear weaponry had on war and foreign affairs.

  • Aaron Peters

    I’m glad that the author used a more recent point of comparison in the form of the 9/11 tragedy to compare the destruction of the Atomic Bombs on the Japanese cities of Hiroshima and Nagasaki. It helps readers who most likely weren’t in living memory. It also goes an excellent job of detailing what lead to the United States deciding to use the Atomic Bomb so late in the war.

  • Kenneth Gilley

    This article was very informative. While the atomic bombs dropped on Hiroshima and Nagasaki did kill tens of thousands of civilians, as a whole, it is likely that the bombs actually saved Japanese lives. Obviously, the bombs saved countless American lives, but given the Japanese attitude towards surrender that made things so difficult for for United States troops in the rest of the Pacific, an invasion of mainland Japan would have been disastrous for all involved.

  • Michael Leary

    Very interesting article, I have often thought on whether the bombs should have been dropped on Japan. I think that although it caused damage to thousands of civilians, it likely saved the lives of millions of Japanese and American soldiers and civilians. This could be seen in how the Japanese fought until the last man in the Pacific islands and the war would have continued for years on the mainland of Japan.

  • Fatima Navarro

    This article was so well written and informative that I see why it was a definite winner. The story was able to convey every piece of information well while also adding the comparison between Pearl Harbor and the attack on 911 and how combined, it would still not be even close to the total deaths that the bombs caused. The bombings are still a debate, if they were dropped rightfully or was it not necessary to do so? Was it necessary to drop two? Whatever the stand on the issue is, one thing is still truth to this day: Hiroshima and Nagasaki will always be the proof that nuclear weapons do more harm than good.

  • Shine Trabucco

    This article communicates and articulates the story very well. The concise structure of the article makes it very easy for a reader to follow along and not get lost while reading. The topic is difficult to write about especially from the American point of view. I remember a debate in a high school class about if dropping the bomb was right or wrong, the two people were never able to find common grounds and answer the difficult questions of humanity.
