In August of 1945, the world had been at war for more than 5 years. The bloody war in Europe had ended a few months before, and Japan was the last country left fighting America and her allies, England, Australia, China, and the USSR. Yet, Japan would not give up. They were in an untenable position in an unwinnable war. Germany had been defeated, Hitler had committed suicide, and Italy had long since joined the Allies. Japan was alone, the last bastion of the Axis, surrounded by enemies, and yet they still refused to surrender. (1) Japan had entered war with China in 1937, before the official start of World War II, seeking to capture resources from Manchuria and some Pacific islands to make Japan into an entirely self-sufficient empire.
One of the principal reasons that the atomic bombings were justified is because more lives would have been lost in an invasion of Japan than were lost during the bombings. During the bombings of Hiroshima and Nagasaki, not a single American life was lost. Hiroshima had no American or Allied citizens in it. While there was a prisoner of war (POW) camp outside of Nagasaki, no Americans were held there, and only 8 Allied POWs died at the camp as a result of the bombing (7 Dutch prisoners, and one citizen of the British Commonwealth). (1) The science of projecting military casualties is an inexact science, and, while projections are not always accurate (the battle of Iwo Jima had projected light casualties, but ultimately, U.S. casualties outnumbered Japanese.), the American military had several previous invasions that gave them a wealth of data to use to predict what would happen when invading Japan itself.
The US military used the invasion of Saipan as a general reference for projecting casualties of the invasion of Japan. This resulted in a “Saipan Ratio” of 1 dead American soldier and several wounded to kill 7 Japanese soldiers. (2) The Japanese had 900,000 regular military troops on Kyushu, (1, Pg. 203) the island where an invasion of Japan would have begun if it had occurred. Using the “Saipan Ratio,” approximately 128,571 American soldiers would have been killed outright, and over 1 million would have been badly injured, for a total casualty count of over 1,100,000. Compare this to the amount of American casualties in the bombings: 0.
As a result of the bombings more than 200,000 Japanese citizens were instantly killed. (3) Many more have died since from effects of the bomb, such as radiation-induced cancer and other maladies. Yet, the Japanese had deployed 900,000 soldiers on Kyushu (1, Pg. 203) to defend against an American invasion, and Japanese soldiers viewed it as dishonorable to surrender. In the battle of Iwo Jima, 21,000 Japanese soldiers were deployed. Of these, 20,703 were killed, with the rest being captured. That means that approximately 98.5% of the deployed soldiers chose death rather than capture. Using that percentage, the 900,000 Japanese soldiers on Kyushu alone could have suffered 886,500 deaths during an American invasion, more than 4 times the deaths caused by the bombs. This figure only counts the military forces on Kyushu, and does not factor in the tens of millions of civilians across the Japanese Home Islands, or the military forces deployed on the other Home Islands. (1, Pg. 203)
A second justification of the atomic bombings is that they occurred during a time of total war. A total war is a war where a nation completely dedicates itself to the war. Tax revenues are used to finance the war, and all citizens are compelled to serve in the armed forces or otherwise contribute to the effort. Therefore, every enemy citizen killed is one less citizen who can contribute to the enemy offense. This makes enemy cities and “civilians” legitimate targets. If every single person is contributing to the war, they are all enemies, and they are all legitimate targets that can be attacked with utmost expedience. Therefore, the bombings were justified because Japan was fighting a total war against America. Work done in Japan went towards the war, and all citizens would have been called upon to fight in case of an American invasion. For example, a teenaged Japanese schoolgirl was conscripted into the forces detailed to protect the Japanese Home Islands. She was issued an awl (a small, pointed tool usually used for making holes in leather) and told “Even killing one American soldier will do… You must aim for their abdomen.” (1, pg. 189) Therefore, the bombings were justified because even Japanese schoolchildren were conscripted into the Army and told to kill Americans. If everyone is being conscripted, then everyone is a legitimate target.
Now, of course, there are dissenting opinions on every topic. Some say that the bombings were inherently immoral. These detractors include Albert Einstein and Leo Szilard, the two men whose joint letter prompted Franklin D. Roosevelt to investigate the possibility of creating an atomic bomb. Szilard said in an interview:
“Let me say only this much to the moral issue involved: Suppose Germany had developed two bombs before we had any bombs. And suppose Germany had dropped one bomb, say, on Rochester and the other on Buffalo, and then having run out of bombs she would have lost the war. Can anyone doubt that we would then have defined the dropping of atomic bombs on cities as a war crime, and that we would have sentenced the Germans who were guilty of this crime to death at Nuremberg and hanged them?” (7)
Basically, Szilard is saying that, were anyone else to have developed and used the bomb, they would be viewed as war criminals and executed. Szilard is incorrect, because, while killing over 200,000 people is, of course, regrettable, World War II was a total war. 200,000 people dying in Hiroshima and Nagasaki is a horrific occurrence, of course, but, in a total war, those 200,000 “civilians” in the cities are as legitimate a target as 200,000 enemy soldiers arrayed on a battlefield against an equal force of other fighting troops, because in a total war, those 200,000 “civilians” are 200,000 people that are directly supporting the enemy war machine.
Another detraction of the attacks is that they were militarily unnecessary. Some say that Japan was so utterly defeated by the time the bombs were dropped that blockading all of their ports could have just as easily defeated them and therefore, we did not need the bombs. While, with other countries, this would have worked, it would not with Japan. Japan was entirely dedicated to the war, and they refused to surrender. America needed to show Japan that any further fighting was thoroughly futile. (1)
There are also detractors that say a simple demonstration of the bomb on an outlying, uninhabited island would have had the same effect as destroying 2 Japanese cities. Again, while this would have worked with other countries, it would not work with Japan. Even destroying Hiroshima did not entirely convince the Japanese of the futility of their struggle. They wrote off the destruction of Hiroshima as a fluke. (1) It was not until America destroyed Nagasaki that the Japanese realized that the threat from America was real and could easily destroy the country. Therefore, the bombings were justified because they drove the threat home, as it were, and made the Japanese realize that total destruction was on the horizon if they did not surrender.
Hiroshima and Nagasaki are significant subjects because they have had lasting impacts. To this day, the bombings are a very sore subject in Japan. Japan’s top military official, their Defense Minister, was forced to step down in July of 2007 after expressing a belief that the bombings “ended the war and, … couldn’t have been helped.” (5, 6) After he made that statement, he was forced out of office because the Japanese people still, to this day, think the bombings were wrong. The bombings have significance for America, as well. At that point, only America had atomic bombs, and the choice to use them reverberates even until today. Using them unleashed the specter of nuclear war upon the whole world to the point that there are, today, more than 25,000 nuclear weapons around the world. This is significant because of how easy it would be for these weapons to be misused, to the detriment of the entire world.
Less than a week after America destroyed Nagasaki, Emperor Hirohito made a radio announcement to the Japanese people declaring that Japan accepted the Potsdam Declaration, in essence declaring Japan’s surrender to the Allies. (1) If America had not dropped the bombs, that surrender would not have come. It would have taken many months, if not years, for an invasion to subdue Japan, or for a blockade to starve the country into submission. It took only two bombs to finally end World War II. Germany had been defeated a few months earlier, and Japan was the last country to be fighting the war against the allies. The bombings were entirely justified because they eliminated a dangerous enemy and, in a total war, anyone who is affiliated with the enemy is an entirely legitimate target.
