Dawn arrives quietly over the East River, its light catching the glass and steel of a city built on negotiations. Flags outside the United Nations hang almost still, as if listening. In moments like this, history does not arrive with sirens; it settles like a weight in the air, noticed only when people pause long enough to feel it.
The ending of the last major nuclear arms control pact between the United States and Russia has unfolded in this subdued way. There was no single dramatic gesture, only the steady expiration of a framework that for decades placed limits, inspections, and a measure of predictability on the world’s largest nuclear arsenals. In recent remarks, the UN secretary-general described the moment as a grave one, warning that its timing could scarcely be worse.
The agreement, long seen as a stabilizing thread left over from the Cold War, constrained deployed strategic nuclear weapons and allowed each side to verify the other’s compliance. Its erosion did not happen overnight. Years of strained relations, mutual accusations, and suspended inspections thinned it gradually, until the legal architecture simply ran out of time. What remains is an absence—of rules, of shared measurements, of the quiet reassurance that someone is still counting.
That absence is felt against a crowded global backdrop. Wars persist, rivalries harden, and new technologies blur old distinctions between conventional and strategic weapons. At the same time, trust between major powers has grown scarce. The UN chief’s warning points less to nostalgia for past treaties than to concern about the present atmosphere: a world already dense with crises, now asked to carry the additional uncertainty of unconstrained nuclear competition.
Arms control, when it works, is rarely visible. It lives in technical annexes, in inspection schedules, in meetings that end without headlines. Its success is measured in what does not happen. Without it, the risks are harder to quantify but easier to imagine—miscalculations, accelerated arms development, and a gradual normalization of danger.
For smaller nations and non-nuclear states, the end of the pact reverberates differently. Many have long argued that the credibility of global nonproliferation efforts depends on restraint by those with the largest stockpiles. When that restraint weakens, so too does confidence in the broader system designed to prevent the spread of the world’s most destructive weapons.
As evening falls and lights come on across the city, diplomacy continues in quieter rooms. Appeals are made for dialogue, for renewed frameworks, for steps that might rebuild a minimum of predictability. The warning from the UN is not a prediction of catastrophe, but a reflection of timing: that this loss arrives when the world feels least prepared to absorb it.
History, after all, often turns not on explosions, but on silences—on agreements that lapse, on conversations that stop. And in those pauses, the future waits, unsettled, for what comes next.
