Hiroshima and Nagasaki: Historical Justification for the Atomic Bombs

Introduction: Scale and Significance of the Atomic Attacks

The events that took place in Hiroshima and Nagasaki in August 1945 represented one of the largest tragedies humanity had experienced throughout its history. The impact is considered immense not so much in terms of the raw destructive power of the bombs, but rather from the perspective of the human damage caused among the Japanese population. There have been numerous discussions over the real necessity of a nuclear strike against the wartime enemy, Japan, and there are arguments both for and against this claim. However, taking into account the war conditions and the deteriorating relations between the US and the USSR, it can be said that — without regard to the civilian casualties — the attacks had a certain historical justification.

The Human and Military Cost of Continued Pacific Warfare

First and foremost, the direction in which the war was heading constituted a solid argument for justifying the attacks. During the war, it was very difficult to accurately determine the number of victims, but it was understood at the time that a continued war in the Pacific would only add to the surging numbers. Moreover, there were growing internal pressures — especially from the American public — to stop the war. In this sense, "the cost of the war was beginning to wear on people's nerves. February [1945] brought a quarter of a million American casualties, including more than 50,000 dead. For the first time in its history the United States was in a war that would cost it more than 1,000,000 casualties. Letters and telegrams poured into government offices. One distraught woman wrote: 'Please, for God's sake, stop sending our finest youth to be murdered in places like Iwo Jima.'"¹

There was, therefore, a growing opposition to the war building up in America. Despite the wave of indignation and frustration triggered by the attacks on Pearl Harbor, public support for continuing the war was weakening as the Allied death toll rose. There was a constant need for a solution that would bring an immediate end to the conflict and to the casualties.

Plans for ending the war — in Europe as well as Asia — still demanded large numbers of soldiers and enormous logistical infrastructure. Specific military operations did not unfold according to initial planning: "the invasion of Iwo Jima was preceded by an immense air and sea bombardment; capture of this tiny island was to take three or four days. Instead, it lasted a month, from mid-February to mid-March 1945; there were 2,500 casualties the first day. Total casualties in taking these eight square miles were 6,821 marines killed and almost 20,000 wounded."³ The large number of victims — both civilian and military — weighed heavily in assessments of the viability of a nuclear strike against Japan. In 1945, an approximate death toll of 220,000 from Hiroshima and Nagasaki was considered to be less than the casualties a prolonged conventional war would have produced.⁴

Economic Pressures and the Drive to End the War

There was also the issue of swiftly ending a war that had caused more damage than expected, with serious economic implications. The war in Europe had been exhausting for Great Britain and France in particular.⁵ There was an urgent need to reconstruct European economies devastated by the war and by sustained aerial bombardment. The capitulation of Germany on 8 May 1945 was seen as the beginning of peace, but the war in Asia remained an active military conflict requiring continued Allied effort. As one historian notes, "Japan had to be brought to surrender."⁶

At the same time, voices within the US government expressed skepticism about conventional alternatives. George Marshall, for instance, "was skeptical that attacking Japanese cities with conventional weapons would end the war, despite what generals with cigars in their mouths had to say about bombing the Japanese into submission."⁷ All of these pressures — on war industries, on national economies whose productive capacity had been severely damaged, and on the internal political environment — made the case for a rapid, decisive end to the conflict in Asia more compelling. The Manhattan Project had, by mid-1945, produced a weapon that seemed capable of delivering exactly that.

Conclusion: Historical Context and Pragmatic Justification

Overall, it can be concluded that, despite the tragic loss of human lives, the nuclear attacks on Hiroshima and Nagasaki could find justification in the historical context and the economic and geopolitical framework of the time. Although morally the bombings lack justification, they may well have saved millions of others from death.
