The 79th anniversaries of the US atomic bombings of Hiroshima and Nagasaki are coming up in August. Rather than commemorating those somber anniversaries as a grim reminder of the past, this year they serve as a foreboding warning of what may be to come.

The Russian war on Ukraine, with its attendant nuclear threats, and an intensifying array of antagonisms among nuclear-armed governments in Northeast Asia, the South China Sea, South Asia, and the Middle East have brought into sharp focus the increasing risks of nuclear war by accident, miscalculation, or crisis escalation, making new efforts to restart disarmament diplomacy an imperative.

Instead, we are seeing progress toward nuclear disarmament slide into reverse. The last remaining US-Russia arms control treaty is set to expire in 2026. The United States is planning to spend $2 trillion over the next 30 years to maintain and modernize its nuclear warheads and delivery systems, and a new multipolar arms race is underway, as all nuclear-armed states are qualitatively and, in some cases, quantitatively upgrading their nuclear arsenals.

Reflecting the urgency of this moment, at the close of its 92nd annual meeting in Kansas City, Missouri, on June 23, the United States Conference of Mayors (USCM) adopted a new resolution, titled,“The Imperative of Dialogue in a Time of Acute Nuclear Dangers.” This is the 19th consecutive year that the USCM has adopted a resolution submitted on behalf of US members of Mayors for Peace.

By adopting this resolution, the USCM, the official nonpartisan association of more than 1,400 American cities with populations over 30,000, has once again charted a responsible path. It “condemns Russia’s illegal war of aggression on Ukraine and its repeated nuclear threats and calls on the Russian government to withdraw all forces from Ukraine.” Importantly, it also calls on the President and Congress “to maximize diplomatic efforts to end the war in Ukraine as soon as possible.”

The resolution welcomes national security advisor Jake Sullivan’s June 2023 invitation to Russia to manage nuclear risks and develop a post-2026 arms control framework, and his signal of US readiness to engage China to ensure that competition does not veer into conflict. It further “encourages our government to pursue any offer made in good faith to negotiate a treaty among nuclear powers barring any country from being the first to use nuclear weapons against one another.”

In an important provision, the resolution “calls on the government of the United States to make good faith efforts to reduce tensions with the government of the People’s Republic of China, seeking opportunities for cooperation on such global issues as the environment, public health, and equitable development, and new approaches for the control of nuclear arms.”

And the resolution welcomes the September 10, 2023, Declaration of the G20 Leaders meeting in Delhi—including leaders or foreign ministers of China, France, India, Russia, the United Kingdom, and the United States—that the “threat of use or use of nuclear weapons is inadmissible.”

Looking to the future, the USCM “calls on the Administration and Congress to reconsider further investments in nuclear weapons and find ways that our finite federal resources can better meet human needs, support safe and resilient cities, and increase investment in international diplomacy, humanitarian assistance and development, and international cooperation to address the climate crisis.”

As an elected official and original sponsor of this resolution, I understand just how precious human life is. It is our responsibility as leaders to ensure we leave this earth in a better place than we inherited it. It’s imperative that we look at the ways we utilize nuclear weapons and the threat thereof, and that we promote meaningful global dialogue to avoid nuclear war and create a culture of peace. I am proud to stand shoulder to shoulder with mayors across the globe as a member of the Mayors for Peace initiative that has led the way.
