On 6 August 1945, the world changed in a flash above Hiroshima. That day marked a grim milestone in military history, yet the act itself sidesteps the designation of a war crime. In this post, we’ll unpack the complex interplay of legal standards and ethical debates of the era that have shielded this event from such infamy. Was it the context of total war, the absence of legal precedents, or the sheer scale of power demonstrated that has kept the atomic bombing out of the war crime category?

The Definition of War Crimes
Determining if Hiroshima’s bombing constitutes a war crime requires a clear grasp of what war crimes entail. They are severe breaches of international humanitarian law during armed conflict, notably the deliberate targeting of civilians, deploying weapons that cannot distinguish between combatants and non-combatants, or inflicting disproportionate harm to civilians.
Justifications for the Bombing
Ending the War Quickly and the Potential Invasion of Japan
The use of the atomic bomb on Hiroshima is a subject of ongoing debate: was it the least harmful option to conclude a war with significant casualties? Advocates maintain that using the bomb was crucial to overcome Japan’s commitment to the Bushido code, which favored death over the dishonor of surrender. By avoiding a full-scale land invasion, which would have likely resulted in immense Allied and Japanese casualties, the bomb’s use is seen by some historians as a means to save millions of lives. The immediate and severe destruction in Hiroshima, and later Nagasaki, quickly led to Japan’s surrender, effectively bringing World War II to a close.
Demonstrating Power and the Rise of the Nuclear Arms Race
The atomic bomb’s unveiling in Hiroshima was not only a display of power but also a strategic deterrent. The United States, by revealing such a formidable weapon, aimed to discourage future conflicts, sending a clear message of its overwhelming military capabilities. This demonstration of force was a significant factor in deterring potential adversaries from engaging in battle, contributing to a delicate balance of power. The presence of such weapons has been a complex factor in international relations, arguably preventing some wars due to the mutual threat of assured destruction.
At the time of the Hiroshima bombing, the international legal system lacked specific laws concerning atomic weaponry. The existing Hague Conventions offered general rules for war conduct reflecting the nature of conflict as understood in the late 19th and early 20th centuries. The conventions could not foresee the technological advancements that would lead to weapons of mass destruction like the atomic bomb.
Post-War Tribunals and the Absence of Hiroshima Prosecutions
The Nuremberg and Tokyo Trials, which took place from 1945 to 1949, were set up by the victorious Allied powers.The Nuremberg Trials were set up by the United States, the United Kingdom, the Soviet Union, and France. The Tokyo Trials saw participation from a wider group of Allied nations: the United States, the United Kingdom, the Soviet Union, France, Australia, Canada, China, India, the Netherlands, New Zealand, and the Philippines. The Nuremberg Trials specifically addressed the crimes of European Axis members, while the Tokyo Trials dealt with Japanese war crimes.
The tribunals resulted in the conviction of several key military and political leaders. However, they did not address the legality of the atomic bombings, which were seen by many as a necessary evil to end the war and save lives on both sides. The conclusion of these tribunals helped to establish a precedent for international law but did not extend to holding individuals accountable for the use of nuclear weapons during the war.

The Moral Debate
The Humanitarian Perspective and Immediate Impact on Civilians
The moral debate around the Hiroshima bombing is deeply rooted in its catastrophic impact on civilians, where over 100,000 individuals perished. The immediate effects, coupled with long-term health consequences such as acute radiation syndrome, increased cancer risks, chronic injuries, psychological trauma, and potential genetic damage, underscore the profound ethical implications. Critics emphasize that the bombing, which obliterated a city with a vast civilian populace, contravened the principles of warfare that require clear differentiation between combatants and non-combatants.
Military Necessity, Targeting Military Installations, and the Principle of Proportionality
Advocates of the bombing cite military necessity, asserting that Hiroshima was a legitimate military target due to its substantial military infrastructure. They argue that targeting these installations aimed to cripple Japan’s war effort and expedite its surrender. The principle of proportionality is also highlighted, balancing the expected military benefit against civilian harm, to justify the atomic bomb’s use.
Determining the exact number of casualties from the atomic bombings of Hiroshima and Nagasaki is challenging due to the extensive destruction and the chaotic conditions at the end of World War II. Despite this, since 1945, efforts have been made to estimate the dead and injured.
The Manhattan Engineer District’s estimates for casualties are as follows:.
The atomic bombings of Hiroshima and Nagasaki in August 1945 stand as somber milestones in human history, marking the first and only use of nuclear weapons in war. In Hiroshima, the bomb known as “Little Boy” had an explosive yield of approximately 15,000 tons of TNT, resulting in the death of about 25.88% of the pre-raid population and injuring another 27.06%. Nagasaki faced the devastation from “Fat Man,” a bomb with a yield of 21,000 tons of TNT, which led to the death of 20.00% of its pre-raid population and injured 12.82%.
These figures are not just numbers; they represent countless individual stories of suffering and loss.
Political Landscape and the Role of Allied Powers
The United States Dominance and the Soviet Union’s Stance
The Soviet Union’s official stance on the bombing of Hiroshima was not immediately clear in the days following the event. The Soviet government under Joseph Stalin was reserved in its public statements, likely due to the complex political situation at the time. The bombing occurred just as the Soviet Union was declaring war on Japan and beginning its invasion of Japanese-held territory in Manchuria.
Privately, however, the Soviet leadership recognized the bombings as a significant shift in military power and an indication of the United States’ newfound strategic dominance. The event underscored the urgency for the Soviet Union to develop its own nuclear capabilities to counterbalance the United States.
The Soviet Union conducted its first successful nuclear test in 1949, just four years after Hiroshima, effectively ending the United States’ monopoly on nuclear weapons. The first atomic bomb developed by the Soviet Union was named “RDS-1” and was often referred to in the West as “Joe-1,” in a nod to Joseph Stalin. The bomb was detonated at the Semipalatinsk test site in Kazakhstan.
Japan’s Post-War Reconstruction and the U.S.-Japan Security Treaty
After World War II, Japan was in ruins, and the United States stepped in to assist in its reconstruction, leading to significant political and economic changes. This rebuilding period was marked by the implementation of democratic reforms, economic aid, and the establishment of a new constitution for Japan, which included the renunciation of war as a sovereign right of the nation.
The U.S.-Japan Security Treaty, initially signed in 1951 and then revised in 1960, was a vital element of the post-war relationship between Japan and the United States. The original 1951 treaty, formally known as the “Treaty of Mutual Cooperation and Security between the United States and Japan,” allowed the United States to maintain armed forces in Japan to defend against external aggression, while Japan was prohibited from possessing a military with offensive capabilities. This arrangement was intended to provide security to Japan, which had been stripped of its right to wage war while ensuring a strategic American military presence in Asia during the Cold War.
The 1960 treaty revision, often called the “U.S.-Japan Security Treaty,” strengthened and updated the two nations’ commitments. The revised treaty provided for mutual defence; if either the United States or Japan were attacked, the other was obliged to act to meet the common danger. It also allowed the United States to maintain military bases in Japan, which served as key strategic points for the U.S. during the Cold War and beyond.
The treaty was controversial in Japan and led to significant protests at its signing, reflecting a national debate over Japan’s post-war identity and its relationship with the United States. Nevertheless, the treaty has endured and remains a cornerstone of the U.S.-Japan alliance, which has become one of the most robust bilateral relationships in the world, encompassing not just security but also economic and cultural ties.
Evolution of War Crime Definitions:
The Geneva Conventions and the International Criminal Court
International legal frameworks, specifically the Geneva Conventions and establishing the International Criminal Court (ICC), have influenced the evolution of war crime definitions.
The Geneva Conventions, initially adopted in 1864 and subsequently revised and expanded, establish the fundamental principles of international humanitarian law (IHL) and provide guidelines for the conduct of armed conflicts. These conventions outline protections for civilians, wounded and sick combatants, prisoners of war, and other individuals affected by armed conflicts. They also define specific war crimes, such as deliberately targeting civilians or engaging in acts of torture and outline the obligations of states to ensure compliance with IHL.
The International Criminal Court (ICC), created in 1998 through the Rome Statute, is a permanent international tribunal responsible for prosecuting individuals with the most significant responsibility for serious international crimes, including war crimes. The ICC has jurisdiction over war crimes committed during international and non-international armed conflicts. Through its jurisprudence, the ICC has contributed to developing war crime definitions and clarifying the elements and scope of various war crimes.
These legal frameworks have played a vital role in shaping the definition and understanding of war crimes. They provide a basis for assessing the legality of specific actions during armed conflicts and holding individuals accountable for violations of international humanitarian law. The ongoing evolution of war crime definitions reflects the collective efforts of the international community to promote accountability, safeguard civilians, and prevent atrocities in times of war.
Hiroshima’s bombing remains a contentious point in history, raising complex moral questions about warfare. It prompts us to consider the nature of conflict and the importance of making ethical decisions under pressure. The ongoing discussions about military ethics remind us of the urgent need for strong international laws to balance military actions with the protection of civilians.
Reflecting on Hiroshima teaches us the value of dialogue, historical understanding, and learning from the past. It’s a message to the next generations to lead with peace, prevent conflicts, and respect human rights, aiming for a fairer, more peaceful world. Hiroshima’s impact is a historical lesson and a signpost for our commitment to a future free from such destruction. Will we honor this commitment, or will history repeat itself?
1. Why wasn’t the bombing of Nagasaki considered a War Crime?
The bombing of Nagasaki isn’t labeled a war crime. The United States decided to use atomic bombs on Hiroshima and Nagasaki during the final stages of World War II to expedite Japan’s surrender and end the warThe bombings of Hiroshima and Nagasaki are debated for targeting military and industrial targets under the guise of military necessity. Critics, however, challenge the proportionality and necessity in relation to the civilian toll.
2. How did the Hiroshima bombing influence International Laws?
The Hiroshima bombing shaped international laws on armed conflict, highlighting the need to regulate weapons of mass destruction and protect civilians. This awareness spurred treaties like the Non-Proliferation of Nuclear Weapons and updates to the Geneva Conventions, aiming to prevent similar devastation and enhance civilian safety during war.
3. Were there any attempts to prosecute the Hiroshima bombing?
No legal proceedings specifically targeted the Hiroshima bombing as a war crime. At the time of the bombings, the international legal framework for war crimes was less developed than it is now. The Nuremberg and Tokyo Trials post-World War II focused on prosecuting leaders for broader categories of war crimes and crimes against humanity, not on the use of specific weapons. Nonetheless, the Hiroshima bombing has significantly influenced ongoing discussions about the legality and morality of nuclear warfare.
4. How has the perception of the Hiroshima bombing changed over time?
he perception of the Hiroshima bombing has shifted over time. Initially, many viewed it as a necessary act to conclude World War II and minimize further loss of life. With time and the emergence of more information about the extensive civilian casualties and suffering, ethical debates intensified. The focus on the human cost has significantly altered the narrative, prompting a reevaluation of the bombings’ justification and the broader implications for warfare and international law.
