New START’s Expiration: A Threat to Humanitarian Disarmament
When major powers abandon restraint in the nuclear field, they send a dangerous message: that international commitments are optional, norms are negotiable, and humanitarian principles can be sidelined.
Feb 05, 2026
In January 2026, I published an article warning that the world was approaching the final hours of the New START Treaty. On February 5, 2026, that warning has become reality. For the first time since the early 1970s, no legally binding limits exist on US-Russian strategic nuclear forces. This moment is not only a failure of arms control; it is a profound threat to human security, humanitarian disarmament, and the credibility of multilateral commitments across all fields.
New START was the last surviving pillar of bilateral nuclear restraint. Its expiration removes the ceilings on deployed strategic warheads and delivery systems, eliminates inspections and data exchanges, and forces both sides to operate in an environment of opacity and worst‑case assumptions. In my earlier article, I argued that this collapse would deepen the crisis of credibility facing the Nuclear Non‑Proliferation Treaty (NPT), especially the long‑neglected obligations under Article VI. That analysis stands even more firmly today. A world without New START is a world where the NPT’s disarmament pillar is no longer eroding slowly—it is cracking openly.
But the consequences extend far beyond the nuclear domain. The end of New START is a blow to humanitarian disarmament as a whole. Treaties such as the Mine Ban Treaty (MBT) and the Convention on Cluster Munitions (CMC) were built on the belief that international law can restrain the most harmful weapons and protect civilians. When major powers abandon restraint in the nuclear field, they send a dangerous message: that international commitments are optional, norms are negotiable, and humanitarian principles can be sidelined when politically inconvenient.
This erosion of respect for international commitments is not isolated. It is part of a wider pattern visible in multiple conflicts, where the use of explosive weapons in populated areas, attacks on medical facilities, and disregard for civilian protection have become disturbingly normalized. The collapse of New START reinforces this trend by weakening the broader culture of compliance that humanitarian disarmament depends on.
Strengthening humanitarian disarmament—from nuclear weapons to landmines, cluster munitions, and all weapons that devastate civilian life—is now an urgent moral responsibility.
The humanitarian and medical consequences of this moment cannot be overstated. Nuclear weapons are not abstract strategic tools; they are instruments of mass suffering. Their use—even once—would overwhelm health systems, destroy infrastructure, contaminate environments, and inflict irreversible harm on generations. The expiration of New START increases the likelihood of miscalculation, escalation, and arms racing at a time when global humanitarian systems are already stretched beyond capacity.
This is why the Treaty on the Prohibition of Nuclear Weapons (TPNW) has gained renewed relevance. Its humanitarian logic—grounded in the lived experiences of survivors and the realities of medical response—offers a principled alternative to the paralysis of traditional arms control. As nuclear‑armed states retreat from their obligations, the TPNW stands as a reminder that disarmament is not only a legal duty but a moral imperative.
Today’s moment demands more than observation. It requires action.
Governments must restore restraint and rebuild trust in multilateral commitments.
Civil society must raise its voice with renewed urgency.
Humanitarian and medical organizations must continue to highlight the human cost of nuclear policies.
And the media must stop treating nuclear risks as distant or technical; they are immediate threats to human life and dignity.
The expiration of New START is not the end of arms control—but it is a warning. A warning that the international system is drifting toward a world where the most destructive weapons are unconstrained, humanitarian norms are weakened, and global commitments lose their meaning.
Strengthening humanitarian disarmament—from nuclear weapons to landmines, cluster munitions, and all weapons that devastate civilian life—is now an urgent moral responsibility, more than ever.

From Nagasaki, a Prescription for Survival
As physicians and health workers, we must educate our communities that there is no adequate medical or humanitarian response to the use of nuclear weapons. Prevention is the only cure.
Oct 07, 2025
80 years following the US atomic bombings of Hiroshima and Nagasaki, the Nobel Peace Prize Group, International Physicians for the Prevention of Nuclear War, or IPPNW, has just completed their 24th World Congress in Nagasaki. This congress brought together 324 intergenerational health professionals, medical students, and activists from the Global South and North from 34 of IPPNW‘s 56 member nations. The theme of this meeting was: "A World Without Nuclear Weapons—Nagasaki as the Last A-bombed City.”
The timing of this year's congress in Nagasaki is significant. Our nuclear world at 80 stands at the brink of nuclear war either by intent, miscalculation, or from disruptive technology. The Bulletin of Atomic Scientists has moved the minute hand of their infamous Doomsday Clock to 89 seconds till midnight, the closest it has been since the atomic bombings. The congress was informed by scientists who included health professionals, radiations experts, climate modelers, members of the disarmament community, elected officials, Hibakusha (survivors of the atomic bombings), and survivors of the over 2,000 global nuclear tests, in addition to academics of various fields and representatives of the Red Cross and World Health Organization (WHO).
The message and significance overall is the urgency and recognition that we are living on borrowed time as a species, ultimately relying on luck for our survival. For when, not if, deterrence fails there can be no survival in any real sense. Indeed, extinction of the human race is a distinct possibility.
As physicians and health workers, we are first responders and health promoters in our communities, and ultimately the planet. In our role as health promoters, we must educate our communities that there is no adequate medical or humanitarian response to the use of nuclear weapons. As such there is no cure to this last epidemic facing humanity. We must prevent what we cannot cure. The only way to prevent this outcome is through the total elimination of nuclear weapons.
We must eliminate nuclear weapons before they eliminate us.
From a peak of roughly 70,000 nuclear weapons in 1987 to our current level of 12,241, we have eliminated over 80% of these weapons. We know how to do this, but lack the political will to do so. As physicians and health workers around the planet, we are charged with returning to our communities to inform them of this imminent risk. Internationally there is a campaign, the International Campaign to Abolish Nuclear Weapons, which brought forth the Treaty on the Prohibition of Nuclear Weapons. This treaty, which entered into force in 2021, makes nuclear weapons illegal to have, store, develop, transfer, or threaten to use and provides a time-bound, verifiable legal agreement among nuclear nations to abolish these weapons. A global majority of 99 countries have taken legal action to join the treaty.
In the United States, there is a campaign called Back from the Brink, which is bringing communities together to abolish nuclear weapons. It is a campaign that can be endorsed by all with the ultimate goal of building political will to educate and advance US federal policy change to take a leading role in abolishing nuclear weapons. Currently endorsed by 487 municipal and state officials and 51 members of Congress endorsing US House Res. 317 and Senate Resolution Res. 323. We must reach out to our elected officials and encourage them to cosponsor these resolutions as well and, if they are unwilling to do so, ask why?
In the words of United Nations Secretary-General António Guterres, “Humanity is just one misunderstanding, one miscalculation away from nuclear annihilation.” While the task before us is daunting and may seem overwhelming, we find hope in the energy, understanding, and commitment of the next generation of health professionals in IPPNW who are joining us in breaking down the silos connecting the twin existential threats of nuclear war and climate change.
Each of us has a role to play with the very real outcome of saving the world and humanity. We must eliminate nuclear weapons before they eliminate us. This is our Rx for Survival.

Defining Our Role in the Wake of the International Day of Peace
At this challenging time, 80 years since the founding of the United Nations and the bombings of Hiroshima and Nagasaki in a world torn apart by war, there is hope for a just, environmentally sustainable, and peaceful world.
Sep 22, 2025
With two significant interconnected anniversaries occurring this week, Sunday marked the 44th anniversary of the United Nations International Day of Peace. This year‘s theme, “Act Now for a Peaceful World,“ is a call to action, identifying individual responsibility and collective power in “cultivating a culture of peace.“
Noting that this year finds a time of global turbulence, tumult, and uncertainty, it is easy to find oneself despairing. Surrendering to this challenge fuels despair. Hope is realized in identifying our individual response and working together to realize collective power. We must discard outmoded “us and them” thinking, realizing that we are one interconnected human family on this fragile planet that will either learn to live together or perish together.
Everyone has a role to play, and each of us must decide what that role is. It is not necessarily a large role or a small role, it is our role. We can no longer assume that “they will take care of it.” They, are us! We must speak up against violence, hate, discrimination, and inequality. We must practice respect and embrace the diversity of our world. The International Day of Peace builds on the Sustainable Development Goals of the United Nations. The theme aligns with the broader UN goals of sustainable development, recognizing that a peaceful world is intrinsically linked to social justice, equality, and environmental sustainability.
This week also marks the 11th anniversary of the “UN International Day for the Total Elimination of Nuclear Weapons” on September 26. With current global nuclear arsenals numbering 12,241 weapons, there is no humanitarian, social, or environmental justice and no sustainability as long as these weapons exist. Everything and everyone we care about is threatened. We must recognize the social and economic costs of the continued existence of these weapons. The United States is spending over $110 billion on all nuclear weapons programs in FY 2025 equating to over $209,000 every minute of every day on these weapons with plans for massive expansion of these expenditures in the years to come under the misguided myths of deterrence and “more is better.“
Ultimately there cannot be peace with the planet until there is peace on the planet.
Fortunately, there is hope in the effort to eliminate these weapons both here at home and around the world. The International Campaign to Abolish Nuclear Weapons was instrumental in the development and adoption of the International Treaty on the Prohibition of Nuclear Weapons, which makes nuclear weapons illegal to have, develop, transfer, use, or threaten to use under international treaty, just as all other weapons of mass destruction are.
At a time when our world is closer to nuclear war than at any time since the bombings of Hiroshima and Nagasaki, 89 seconds till “Doomsday” per the Bulletin of Atomic Scientists, there is a growing movement here in the United States to eliminate these weapons. It is called Back From the Brink. This movement that supports the international effort is bringing communities together to abolish nuclear weapons and making the connection between our future and sustainability goals. Currently there are 502 national organizations, 78 municipalities and counties, eight state legislative bodies, 487 municipal and state officials, and 51 members of Congress endorsing. The people‘s voice is rising and being heard and is the best way to affect federal policy. When the people speak, the leaders will follow. This movement can be endorsed by all, and everyone is encouraged to take the simple action of reaching out to your elected officials, both in the US House, Senate, and local officials to endorse this campaign.
So at this challenging time, 80 years since the founding of the United Nations and the bombings of Hiroshima and Nagasaki in a world torn apart by war, there is hope for a just, environmentally sustainable, and peaceful world. Ultimately there cannot be peace with the planet until there is peace on the planet. The choice is ours. It is in our hands on this week of the International Day of Peace.
