On February 5, with the expiration of the New Strategic Arms Reduction Treaty, or New START, the only bilateral arms control treaty left between the United States and Russia, we are guaranteed to find ourselves ever closer to the edge of a perilous precipice. The renewed arms race that seems likely to take place could plunge the world, once and for all, into the nuclear abyss. This crisis is neither sudden nor surprising, but the predictable culmination of a truth that has haunted us for nearly 80 years: Humanity has long been living on borrowed time.

In such a context, you might think that our collective survival instinct has proven remarkably poor, which is, at least to a certain extent, understandable. After all, if we had allowed ourselves to feel the full weight of the nuclear threat we’ve faced all these years, we might indeed have collapsed under it. Instead, we continue to drift forward with a sense of muted dread, unwilling (or simply unable) to respond to the nuclear nightmare. In a world already armed with thousands of omnicidal weapons, such fatalism—part suicidal nihilism and part homicidal complacency—becomes a form of violence in its own right.

Given such indifference, we risk not only our own lives but also the lives of all those who would come after us. As Jonathan Schell observed decades ago, both genocide and nuclear war are distinct from other forms of mass atrocity in that they serve as “crimes against the future.” And as Robert Jay Lifton once warned, what makes nuclear war so singularly horrifying is that it would constitute “genocide in its terminal form,” a destruction so absolute as to render the Earth unlivable and irrevocably reverse the very process of creation.

Yet for many, the absence of such a nuclear holocaust, 80 years after the US dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki, is taken as proof that such a catastrophe is, in fact, unthinkable and will never happen. These days, to invoke the specter of annihilation is to be dismissed as alarmist, while to argue for the abolition of such weaponry is considered naïve. As it happens, though, the opposite is true. It’s the height of naïveté to believe that a global system built on the supposed security of nuclear weapons can endure indefinitely.

Nuclear weapons are human creations, and what is made by us can be dismantled by us.

That much should be obvious by now. In truth, we’ve clung to the faith that rational heads will prevail for far too long. Such thinking has sustained a minimalist global nonproliferation regime aimed at preventing the further spread of nuclear weapons to so-called terrorist states like Iraq, Libya, and North Korea (which now indeed has a nuclear arsenal). Yet, today, it should be all too clear that the states with nuclear weapons are, and have long been, the true rogue states.

A nuclear-armed Israel has, after all, been committing genocide in Gaza and has bombed many of its neighbors. Russia continues to devastate Ukraine, which relinquished its nuclear arsenal in 1994, and its leader, Vladimir Putin, has threatened to use nuclear weapons there. And a Washington led by a brazen authoritarian deranged by power, who has declared that he doesn’t “need international law,” has stripped away the fragile façade of a rules-based global order.

Donald Trump, Vladimir Putin, and the leaders of the seven other nuclear-armed states possess the unilateral capacity to destroy the world, a power no country should be allowed to wield. Yet even now, there is still time to avert catastrophe. But to chart a reasonable path forward, it’s necessary to look back eight decades and ask why the world failed to ban the bomb at a moment when the dangerous future we now inhabit was already clearly foreseeable.

With Hiroshima and Nagasaki still smoldering ruins, people everywhere confronted a rupture so profound that it seemed to inaugurate a new historical era, one that might well be the last. As news of the atomic bombings spread, a grim consensus took shape that technological “progress” had outpaced political and moral restraint. Journalist Norman Cousins captured the zeitgeist when he wrote that “modern man is obsolete, a self-made anachronism becoming more incongruous by the minute.” Human beings had clearly fashioned themselves into vengeful gods, and the specter of Armageddon was no longer a matter of theology but a creation of modern civilization.

In the United States, of course, a majority of Americans greeted the initial reports of the atomic bombings of those two Japanese cities in a celebratory fashion, convinced that such unprecedented weapons would bring a swift, victorious end to a brutal war. For many, that relief was inseparable from a lingering desire for retribution. In announcing the first atomic attack, President Harry Truman himself declared that the Japanese “have been repaid many fold” for their strike on Pearl Harbor, which inaugurated the official American entry into World War II. Yet triumph quickly gave way to a more somber reckoning.

As the scale of devastation came into fuller view, the psychological fallout radiated far beyond Japan. The New York Herald Tribune captured a growing unease when it editorialized that “one forgets the effect on Japan or on the course of the war as one senses the foundations of one’s own universe trembling a little… it is as if we had put our hands upon the levers of a power too strange, too terrible, too unpredictable in all its possible consequences for any rejoicing over the immediate consequences of its employment.”

Some critics of the bombings would soon begin to frame their concerns in explicitly moral terms, posing the question: Who had we become? Historian Lewis Mumford, for example, argued that the attacks represented the culmination of a society unmoored from any ethical foundations and nothing short of “the visible insanity of a civilization that has ceased to worship life and obey the laws of life.” Religious leaders voiced similar concern. The Christian Century magazine typically condemned the bombings as “a crime against God and humanity which strikes at the very basis of moral existence.”

As the apocalyptic imagination took hold, others turned to a more self-interested but no less urgent question: What will happen to us? Newspapers across the country began running stories on what a Hiroshima-sized bomb would do to their downtowns. Yet Philip Morrison, one of the few scientists to witness both the initial Trinity Test of the atomic bomb and Hiroshima after the bombing, warned that even such terrifying projections underestimated the danger.

Deaths in the hundreds of thousands were, he insisted, far too optimistic. “The bombs will never again, as in Japan, come in ones or twos. They will come in hundreds, even in thousands.” And given the effect of radiation, those who made “remarkable escapes,” the “lucky” ones, would die all the same. Imagining a prospective strike on New York City, he wrote of the survivors who “died in the hospitals of Philadelphia, Pittsburgh, Rochester, and Saint Louis in the three weeks following the bombing. They died of unstoppable internal hemorrhages… of slow oozing of the blood into the flesh.” Ultimately, he concluded, “If the bomb gets out of hand, if we do not learn to live together… there is only........
