August 6th U.S. Atomic Bombing of Hiroshima Commemoration in Santa Fe

Eighty Years Later, it is Beyond Time to Get Rid of Nuclear Weapons.

Last week on August 6, 2025, the 80th anniversary of the U.S. atomic bombing of Hiroshima, community members gathered at the Center for Progress and Justice on Cerrillos Road in Santa Fe to honor the solemn occasion and demand an end to the ongoing nuclear weapons harm and destruction that first began here in New Mexico.

The event was organized by Nuclear Watch New Mexico in collaboration with the Up in Arms campaign by Ben Cohen, co-founder of Ben & Jerry's, to reduce military and nuclear weapons spending, the International Campaign to Abolish Nuclear Weapons (winners of the 2017 Nobel Peace Prize), the Santa Fe Archdiocese, the Back from the Brink New Mexico Hub, and the Tularosa Basin Downwinders Consortium. It centered around a massive public art installation from Up in Arms of a towering cubic structure framed by messages on top of images of $100 bills. The structure is sized to literally hold $100 billion of those bills, respresenting what the U.S. spends every year on nuclear weapons (the total cost of nuclear weapons "modernization" is up to $2 trillion). Visible to thousands of drivers each day, the large installation pressures viewers to reckon with the scale of this cost and to imagine what else those resources could make possible. A prominent message on one of the four sides quotes the president in saying, "'We don't need to build brand new ones. We already have so many,' — Donald Trump" and below it, "His budget includes a down payment of $2 trillion of nuclear weapons." Another side reads, "The current U.S. nuclear arsenal is the equivalent of 50,00 Hiroshima explosions. One nuclear bomb killed over 100,000 people in Hiroshima."

The installation will remain on display for the foreseeable future, GO SEE IT NOW! 1420 Cerrillos Road, Santa Fe, NM 87505.

During the event, speakers Archbishop John C. Wester (by video from Japan), Tina Cordova of the Tularosa Basin Downwinders, Sophie Stroud from Nuclear Watch New Mexico, Anne Pierce-Jones from Back from the Brink, Ben Cohen representing Up in Arms, and Seth Shelden from ICAN all gave concrete steps and actions that concerned citizens can take to help promote a safer world. The speakers were presented by former Santa Fe County Commissioner Anna Hansen, who stated, “Disarmament is the only answer. I have spent my life working to end the nuclear cycle, as many have, and most of us in this room have never known a world without nuclear weapons.”

Speakers drew connections between the devastation in Hiroshima and the continued production of plutonium pits at LANL. At Los Alamos National Lab alone, five billion dollars will be poured into nuclear weapons programs in Fiscal Year 2026, starting this October. One billion dollars was added to last year’s budget, which includes a 42% increase for nuclear warheads. At the same time, nonproliferation programs are being cut, the science budget sliced in half, and funds for renewable energy zeroed out and gone completely. The push for "modernization" of the US’s nuclear arsenal is directly linked to plutonium pit production at Los Alamos, specifically expanding plutonium pit production. LANL will receive $1.7 billion in direct costs for pit production in 2026. Add in the indirect costs, and it’s roughly double that. All of this future pit production is exorbitantly expensive, yet the National Nuclear Security Administration still has no credible cost estimate for these plans.

WHAT YOU NEED TO KNOW: New plutonium pits are not needed to maintain the existing stockpile - it is all for future, new designs. And these new weapons cannot be tested because of the testing moratorium - or conversely could pressure the US to resume testing. In 2006, independent experts concluded that existing plutonium pits last at least a century. Their average age now is about 43 years. A new pit aging study is expected this year. Expansion plans should stop until then.

The U.S.’s $2 trillion “modernization” program is a plan to keep nuclear weapons forever. It is claimed to be essential for “deterrence.” But deterrence relies upon the flawed assumption that all actors will behave rationally, and that accidents or miscalculations will never occur. History says otherwise. Moreover, the U.S. and Russia have always rejected minimal deterrence in favor of nuclear warfighting capabilities that could end civilization overnight. That is why we have 1,000s of nuclear weapons and are funneling billions of dollars into mass death machines, even though everybody knows that a nuclear war must never be fought and can never be won.

NukeWatch in DC Lobbying for Nuclear Disarmament and Non-Proliferation

Your Nuclear Watch New Mexico team has just returned from a weeklong trip to Washington D.C. (we went so you don’t have to!). The Alliance for Nuclear Accountability (ANA) hosts an annual “DC Days” conference and following Spring Meeting, and we proudly joined as part of a record number of groups this year. Over 60 individuals from 30+ organizations journeyed to DC to lobby congress on nuclear weapons, energy, and waste policy on behalf of the frontline nuclear communities we represent. Members were present from groups representing the entire U.S. nuclear complex, including sites in Georgia, New Mexico, Tennessee, California, Missouri, Colorado, Idaho, Nevada and beyond. NukeWatch NM brought all three staff members—Jay Coghlan, Scott Kovac, and Sophia Stroud (whose participation was made possible by a youth scholarship from ANA)—to participate in DC Days and the subsequent two-day spring meeting. The ANA DC Days schedule included over 70 meetings with senators, representatives, and other relevant agencies, such as the Department of Energy, the Government Accountability Office, and the Defense Nuclear Facilities Safety Board. Our NukeWatch team attended nearly 30 of these meetings. The Alliance for Nuclear Accountability put together a new report to present our “asks” to congress as a coalition, including analysis and recommendations for nuclear weapons, nuclear waste, and nuclear energy policy and funding. Please click HERE for the full report, and HERE for a short summary.

I was glad to see increased representation from Nevada this year, and especially Indigenous representation. In light of the current administration’s attacks on Environmental Justice, it is more important than ever that ANA as a whole, as well as individual member groups, continue to prioritize uplifting Native American voices, not only because of their deep cultural, spiritual, and social connections to the land, including sacred sites and traditional knowledge essential to religious freedom and access, but also because of the violent legacy and ongoing reality of nuclear colonialism, in which Indigenous lands and peoples have been deliberately and disproportionately targeted in the nuclear industry with uranium mining, nuclear weapons testing and production, and the disposal of radioactive waste.

Your NukeWatch NM Team in DC!

Your Nuclear Watch New Mexico team has just returned from a weeklong trip to Washington D.C. (we went so you don’t have to!). We proudly joined the Alliance for Nuclear Accountability (ANA) in their annual “DC Days” conference and following Spring Meeting, where over 60 individuals from 30+ groups journeyed to DC to lobby congress on nuclear weapons, energy, and waste policy on behalf of the frontline nuclear communities we represent. From across the U.S. near nuclear complex sites in Georgia, New Mexico, Tennessee, California, Missouri, Colorado, Idaho, Michigan and beyond, members were present from the following groups: Beyond Nuclear, Georgia Women’s Action for New Directions, Nuclear Age Peace Foundation, Nuclear Watch New Mexico, Oak Ridge Environmental Peace Alliance, Parents Against Santa Susana Field Laboratory, Peaceworks Kansas City, Physicians for Social Responsibility – Los Angeles & Wisconsin, Rocky Mountain Peace & Justice Center, Snake River Alliance, Southwest Research and Information Center, Tri-Valley Communities Against a Radioactive Environment, and Women’s International League for Peace and Freedom. There were also a number of individual attendants participating from groups not currently affiliated with ANA as official members, notably more than previous years, which lends optimism for the potential growth of DC Days and ANA as a whole.

The Second Meeting of States Parties on the Prohibition of Nuclear Weapons

Since the invasion of Ukraine nearly two years ago, to the recent situation in Israel/Gaza, the risk of impending nuclear war has been a reality considered by many for the first time.  As stated at a side event during the weeklong meeting of States Parties on the Prohibition of Nuclear Weapons (TPNW) held last week from November 27 to Decmber 1st, Hirotsugu Terasaki, Director General of Peace and Global Issues, Soka Gakkai International (SGI), warned that the wide-scale violence brought by these two events “continue to heighten the risk that nuclear weapons could actually be used.” This fear is made all the more tangible when considering also that earlier this month, the Putin announced Russia would be revoking its ratification of the Comprehensive Test Ban Treaty (CTBT), which Terasaki pointed out is a “serious setback for the cause of nuclear disarmament.”

As stated in the article, The Voices of Victims of Nuclear Weapons Testing, “these realities make convening the current Second Meeting of States Parties of the TPNW, which concludes December 1, all the more important and a crucial opportunity to revive momentum for nuclear disarmament and abolition.”

Breakthrough Study Bolsters RECA Claims for New Mexicans Exposed to Trinity Test Site Radiation

Plutonium Detections From Trinity Test Discovered 78 years After Test – Confirm RECA Must Be Expanded

Located in the Tularosa Basin in southern New Mexico, the Trinity Test Site marks the location of the first detonation of a nuclear weapon. Christopher Nolan’s “Oppenheimer” would have you believe this area is desolate, inhospitable and uninhabited. Contrary to this narrative and popular opinion, The area where the Trinity test occurred was not  uninhabited. There were more than 13,000 New Mexicans living within a 50-mile radius. Many of those children, women and men were not warned before or after the test. The event marking the dawn of the nuclear age in July 1945 ushered in decades of health issues for residents living downwind due to exposure to radioactive fallout. The long-lasting impact of radiation exposure is a painful legacy that the New Mexican communities have had to bear.


New preliminary information strongly supports Radiation Exposure Compensation Act (RECA) status for New Mexicans downwind of the Trinity Test Site. In the past weeks, Michael E. Ketterer, (Professor Emeritus, Chemistry and Biochemistry, Northern Arizona University, Flagstaff, AZ) has completed a short “proof of principle” study that directly investigates where plutonium in soils originates by analyzing isotopic ratios, in a known portion of the Trinity Test plume.

Dr. Ketterer sampled soils along highways NM 42, US 54, NM 55, US 60, and US 380. The isotopes show that there is definitely plutonium from the Trinity Test in the northeast plume, and distinguishes it from global (stratospheric) background and New Mexico regional background from Nevada Test Site fallout. Soils along all five of these highways contain plutonium that reflects mixtures of Trinity Test debris and global/Nevada regional background fallout; in some cases, nearly 100% of the Pu originates from the Trinity Test.

Does New Mexico Deserve Downwinder Status: Definitely Yes, as Evident Via Plutonium Isotopes in 2023 Soil Samples

Michael E. Ketterer, Professor Emeritus, Department of Chemistry and Biochemistry
Northern Arizona University , Flagstaff AZ

Introduction/objective: to investigate whether plutonium from the July 16, 1945 Trinity Test can be identified in contemporary soils and dusts near the Trinity Site. A proof-of concept study was conducted via a small-scale July 2023 collection of soil samples along five public highways transecting the areas reported to be most affected (refer to 239+240Pu deposition inventory map from Beck et al., 2020). More-distant soil samples were obtained from the Carson National Forest near Truchas, New Mexico.
