( Tomdispatch.com ) – In recent months, nuclear weapons have reemerged in global headlines. Nuclear-armed rivals India and Pakistan approached the brink of a full-scale war, a confrontation that could have become an extinction-level event, with the potential to claim up to two billion lives worldwide.
The instability of a global order structured on nuclear apartheid has also come into sharp relief in the context of the recent attacks on Iran by Israel and the United States. That system has entrenched a dangerous double standard, creating perverse incentives for the proliferation of world-destroying weaponry, already possessed by nine countries. Many of those nations use their arsenals to exercise imperial impunity, while non-nuclear states increasingly feel compelled to pursue nuclear weapons in the name of national security and survival.
Meanwhile, the largest nuclear powers show not the slightest signs of responsibility or restraint. The United States, Russia, and China are investing heavily in the “modernization” and expansion of their arsenals, fueling a renewed arms race. And that escalation comes amid growing global instability contributing to a Manichean world of antagonistic armed blocs, reminiscent of the Cold War at its worst.
The nuclear threat endangers not only global peace and security but the very continuity of the human species, not to speak of the simple survival of life on Earth. How, you might wonder, could we ever have arrived at such a precarious situation?
The current crisis coincides with the 80th anniversary of the Trinity Test, the first detonation of an atomic weapon that would soon obliterate the Japanese cities of Hiroshima and Nagasaki and so inaugurate the atomic age. So many years later, it’s worth critically reassessing the decisions that conferred on humanity such a power of self-annihilation. After all, we continue to live with the fallout of the choices made (and not made), including those of the scientists who created the bomb. That history also serves as a reminder that alternative paths were available then and that another world remains possible today.
A Tale of Two Laboratories
In the summer of 1945, scientists and technicians at Los Alamos National Laboratory in New Mexico worked feverishly to complete the construction of the atomic bomb. Meanwhile, their colleagues at the University of Chicago’s Metallurgical Laboratory mounted a final, ultimately unsuccessful effort to prevent its use.
The alarm spreading in Chicago stemmed from a sobering realization. The Manhattan Project that they had joined on the basis of a belief that they were in an existential arms race with Nazi Germany had, by then, revealed itself to be a distinctly one-sided contest. Until then, the specter of a possible German atomic bomb had conferred a sense of urgency and a veneer of moral legitimacy on what many scientists otherwise recognized as a profoundly unethical undertaking.
Prior to the fall of Berlin, Allied intelligence had already begun to cast serious doubt on Germany’s progress toward developing an atomic weapon. By April 1945, with the Nazi regime in a state of collapse and Japan’s defeat imminent, the threat that served as the original justification for the bomb’s development had all but vanished.
No longer represented as a plausible deterrent, the bomb now stood poised to become what Los Alamos Director J. Robert Oppenheimer would describe shortly after the war as “weapons of terror, of surprise, of aggression… [used] against an essentially defeated enemy.”
By that point, it was evident that the bomb would be used not to deter Germany but to destroy Japan, and not as the final act of World War II but as the opening salvo of what would become the Cold War. The true target of the first atomic bomb wasn’t, in fact, Tokyo, but Moscow, with the people of Hiroshima and Nagasaki sacrificed on the altar of American global imperial ambition.
For the scientists at Chicago, that new context demanded new thinking. In June 1945, a committee of physicists led by James Franck submitted a report to Secretary of War Henry Stimson warning of the profound political and ethical consequences of employing such a bomb without exhausting all other alternatives. “We believe,” the Franck Report stated, “that the use of nuclear bombs for an early, unannounced attack against Japan [would be] inadvisable.” The report instead proposed a demonstration before international observers, arguing that such a display could serve as a gesture of goodwill and might avert the need to use the bombs altogether.
One of that report’s signatories, Leo Szilard, who had been among the bomb’s earliest advocates, further sought to prevent what he had come to recognize as the catastrophic potential outcome of their creation. With Germany defeated, he felt a personal responsibility for reversing the course he had helped set in motion. Echoing concerns articulated in the Franck Report, he drafted a petition to be circulated among the scientists. While acknowledging that the bomb might offer short-term military and political advantages against Japan, he warned that its deployment would ultimately prove morally indefensible and strategically self-defeating, a position which would also be held by six of the seven U.S. five-star generals and admirals of that moment.
Szilard emphasized that the atomic bomb wasn’t just a more powerful weapon but a fundamental transformation in the nature of warfare, an instrument of annihilation. He already feared Americans might come to regret that their own government had sown the seeds of global destruction by legitimizing the sudden obliteration of Japanese cities, a precedent that would render a heavily industrialized, densely populated country like the United States especially vulnerable.
Moreover, he concluded that using such weapons of unimaginable destructive power without sufficient military justification would severely undermine American credibility in future arms control efforts. He observed that the development of the bomb under conditions of extreme wartime secrecy had created an abjectly anti-democratic situation, one in which the public was denied any opportunity to deliberate on such an irrevocable and consequential decision.
As Eugene Rabinowitch, a co-author of the Franck Report (who would later co-found The Bulletin of Atomic Scientists), would note soon after, the scientists in Chicago were growing increasingly uneasy in the face of escalating secrecy: “Many scientists began to wonder: against whom was this extreme secrecy directed? What was the sense of keeping our success secret from the Japanese? Would it have helped them to know that we had an atomic bomb ready?”
Rabinowitch concluded that the only “danger” posed by such a disclosure was that the Chicago scientists might be proven right, and Japan might surrender. “Since there was no justifiable reason to hold the bomb secret from the Japanese,” he argued, “many scientists felt that the purpose of deepened secrecy was to keep the knowledge of the bomb… from the American people.”
In other words, officials in Washington were concerned that a successful demonstration might deprive them of the coveted opportunity to use the bomb and assert their newly acquired monopoly (however temporary) on unprecedented power.
The Road to Trinity and the Cult of Oppenheimer
Seventy scientists at Chicago endorsed the Szilard Petition. By then, however, their influence on the project had distinctly diminished. Despite their early contributions, notably the achievement of the first self-sustained nuclear chain reaction in December 1942, the project’s center of gravity had shifted to Los Alamos.
Recognizing this, Szilard sought to circulate the petition among his colleagues there, too, hoping to invoke a shared sense of scientific responsibility and awaken their moral conscience in the critical weeks leading up to the first test of the weapon. Why did that effort fail? Why was there so little dissent, debate, or resistance at Los Alamos given the growing scientific opposition, bordering on revolt, that had emerged in Chicago?
One answer lies in Oppenheimer himself. In popular culture and historical scholarship, his legacy is often framed as that of a tragic figure: the reluctant architect of the atomic age, an idealist drawn into the ethically fraught task of creating a weapon of mass destruction compelled by the perceived exigencies of an existential war.
Yet the myth of him as a Promethean figure who suffered for unleashing the fundamental forces of nature onto a society unprepared to bear responsibility for it obscures the extent of his complicity. Far from being a passive participant, in the final months of the Manhattan Project, he emerged as a willing collaborator in the coordination of the coming atomic bombings of Hiroshima and Nagasaki.
When Oppenheimer and physicist Edward Teller (who would come to be known as “the father of the hydrogen bomb”) received Szilard’s petition, neither shared it. While Oppenheimer offered no response, Teller provided a striking explanation: “The things we are working on are so terrible that no amount of protesting or fiddling with politics will save our souls.” He further rejected the idea that he held any authority to influence the bomb’s use. “You may think it is a crime to continue to work,” he conceded, “but I feel that I should do the wrong thing if I tried to say how to tie the little toe of the ghost to the bottle from which we just helped it escape.”
Teller later claimed to be in “absolute agreement” with the petition, but added that “Szilard asked me to collect signatures… I felt I could not do so without first seeking Oppenheimer’s permission more directly. I did so and Oppenheimer talked me out of it, saying that we as scientists have no business meddling in political pressure of that kind… I am ashamed to say that he managed to talk me out of [it].”
Teller’s explanation was likely self-serving given his later acrimonious rift with Oppenheimer over the hydrogen bomb. Yet further evidence indicates that Oppenheimer actively sought to suppress debate and dissent. Physicist Robert Wilson recalled that upon arriving at Los Alamos in 1943, he raised concerns about the broader implications of their work and the “terrible problems” it might create, particularly given the exclusion of the Soviet Union, then an ally. The Los Alamos director, Wilson remembered, “didn’t want to talk about that sort of thing” and would instead redirect the conversation to technical matters. When Wilson helped organize a meeting to discuss the future trajectory of the project in the wake of Germany’s defeat, Oppenheimer cautioned him against it, warning that “he would get into trouble by calling such a meeting.”
The meeting nonetheless proceeded, with Oppenheimer in attendance, though his presence proved stifling. “He participated very much, dominating the meeting,” Wilson remembered. Oppenheimer pointed to the upcoming San Francisco Conference to establish the United Nations and insisted that political questions would be addressed there by those with greater expertise, implying that scientists had no role to play in such matters and ought to abstain from influencing the applications of their work.
Reflecting on his mindset at the time, Oppenheimer explained, “When you see something that is technically sweet, you go ahead and do it and you argue about what to do about it only after you have had your technical success. That is the way it was with the atomic bomb.” In a similar vein, his oft-quoted remark that “the physicists have known sin” was frequently misinterpreted. He was not referring, he insisted, to the “sin” of the destruction of Hiroshima and Nagasaki, but to pride for “intervening explicitly and heavy-handedly in the course of human history.”
When situated within this broader context of a professed commitment to scientific detachment, Oppenheimer’s behavior becomes more intelligible. In practice, however, his stated ideals stood in stark contrast to his conduct. While he claimed to reject political engagement, he ultimately intervened in precisely such a manner, using his position to advocate forcefully for the bomb’s immediate military use against Japan without prior warning. He emerged as a leading opponent of any prospective demonstration, cautioning that it would undermine the psychological impact of the bomb’s use, which could only be realized through a sudden, unannounced detonation on a relatively untouched, non-military target like the city of Hiroshima. This position stood in sharp contrast to that of the Chicago scientists, of whom only 15% supported using the bomb in such a manner.
That climate of deference fostered a culture of complicity, where questions of social responsibility were subordinated to uncritical faith in authority. Reflecting on that dynamic, physicist Rudolf Peierls acknowledged, “I knew that Oppenheimer was on a committee and was briefing with the high-ups. I felt there were two things one could rely on: Oppenheimer to put the reasonable ideas across, and that one could trust people. After all, we are not terrorists at heart or anything… Both these statements might now be somewhat optimistic.”
Ultimately, the only member of Los Alamos to register dissent was Joseph Rotblat, who quietly resigned on ethical grounds after learning in November 1944 that there was no active Nazi atomic bomb program. His departure remained a personal act of conscience, however, rather than an effort to initiate a broader moral reckoning within the scientific community.
“Remember Your Humanity”
The legacy of Oppenheimer, a burden we all now carry, lies in his mistaking proximity to power for power itself. Rather than using his influence to restrain the bomb’s use, he exercised what authority he had to facilitate its most catastrophic outcome, entrusting its consequences to political leaders who soon revealed their recklessness. In doing so, he helped lay the groundwork for what President Dwight D. Eisenhower would, in his farewell address to Congress in 1961, warn against as “the disastrous rise of misplaced power.”
Yet we are not doomed. This history should also remind us that the development and use of nuclear weapons was not inevitable. There were those who spoke out and a different path might well have been possible. While we cannot know exactly how events would have unfolded had dissent been amplified rather than suppressed, we can raise our own voices now to demand a safer, saner future. Our collective survival may well depend on it. How much longer a world armed with nuclear weapons can endure remains uncertain. The only viable path forward lies in renewing a commitment to, as Albert Einstein and Bertrand Russell urged, “remember your humanity, and forget the rest.” With ever more nations developing increasingly powerful arsenals, one thing remains clear: as the Doomsday Clock moves ever closer to midnight, there is no time to waste.
